A battery is a reusable current source that is designed to accumulate and store energy. Its work is based on reversible redox reactions, which makes it possible to use the battery repeatedly. To create a battery, several batteries are connected in one circuit.
Types of batteries
For household appliances and tools, several types are used batteries which differ in the materials used for their manufacture.
Nickel Cadmium (NiCd)
This battery withstand a large number of discharges and charges, resistant to low temperatures and it has a large allowable discharge current. One of its main advantages is low price and long service life. The disadvantages of this type are that it quickly self-discharges and has a low energy density.
The main disadvantage of such equipment is the “memory effect”, which leads to a decrease in usable capacity when the battery is not completely discharged. To restore the nominal power, it is necessary to completely discharge and then charge this device again. To increase the service life of such equipment, it is necessary to completely discharge it and only then put it on charge. For charging, you must use only the device that came with the kit, or one that meets the requirements of the battery manufacturer.
Nickel Metal Hydride (NiMh)
Such batteries appeared later, and they are more promising. Now they are massively used for various household appliances, but even more progressive types are used for phones and laptops.
Lithium-ion (LiIon)
Such a battery is most often used to power laptops, cameras and other equipment, but it is rarely used in modern phones, as it is being replaced by a more advanced type of battery. Their main drawback is their high sensitivity to overcharging, therefore, in devices where such batteries are used, a controller must be installed that limits the charge.
Lithium Polymer (LiPol)
Most modern devices, their main difference is that the electrolyte is gel-like, so such batteries can be very thin. They are most often used in mobile phones, players and other equipment that is small in size. Since such batteries are also sensitive to overcharging, they cannot be used in devices with a faulty charge controller. If the tightness is also broken, such a battery cannot be operated.
Device
In the past, batteries for household appliances and phones were exactly the same as those used in cars. Modern technologies allowed the development of lithium-ion batteries, in which the cathode is covered with aluminum and the anode with copper foil. Lithium polymer models use soft bags as cans, which are filled with a gel-like solution of lithium in polymer.
To control the charge, such a battery must have a device that is made in the form of an electronic board. Instead of the usual two contacts, such batteries are connected to the telephone board using a convector - a multi-pole connection.
Principle of operation
Regardless of the type, any battery works due to the presence of a voltage difference between metal plates immersed in an electrolyte.
The chemical processes occurring in the battery are reversible, therefore, after it is discharged, it is possible to restore working capacity with the help of a charge. During charging, the current is passed in the opposite direction, which will be when the battery is discharged.
The main characteristic is capacity, that is, the amount of charge that a fully charged battery can give when discharged to the smallest allowable value. Ah is usually used to measure it.
Areas of use
The battery is used in various industries and has wide application. Rechargeable batteries are used to illuminate cars, power various apertures on cars, in mobile phones, in household appliances and electronics.
In order to protect the computer and the available information in the event of a sudden power failure, are used. Its main element is the battery. The initial start of any car is not possible without a charged battery.
How to choose a battery
Consider the features of choosing a battery for mobile phone. First you need to figure out which battery is installed in your phone, as it can be removable or non-removable.
If it can be removed, then open the back cover of the phone and carefully study the characteristics of the battery:
- Capacity.
- Model.
- Voltage.
If there is also a non-removable battery, its data can be found in the phone's passport or on the manufacturer's website. Modern market offers original batteries, similar and "noname". It is better not to pay attention to the last option at all, since such a battery can not only disable the phone, but even explode.
Between themselves, the original and analog products practically do not differ in their characteristics, but the original batteries will be much more expensive. Please note that some manufacturers do not original spare parts, so in this case you will have to purchase a similar power supply.
car battery
In this case, it is necessary to pay attention to such characteristics as capacitance, starting current and dimensions of the product. It is important that the capacity and starting current are not very different from the battery that was installed at the factory, since the generator and other equipment are designed for their specific values.
In addition to the described characteristics, pay attention to the presence additional elements Features: handle for easy transportation, terminal protection, built-in charge indicator.
Advantages and disadvantages
Consider what are the advantages and disadvantages of different types of batteries.
Advantages of NiCd devices:
- Fast charging, you can use a current that is equal to or even exceeds the battery capacity, it is often impossible to abuse a large charging current, and if necessary fast charge, then use devices that determine the full charge of the battery, after which they should turn off.
- They can deliver high current to the load.
- If the operating rules are followed, then the service life will be long.
- Possibility of recovery in case of capacity decrease.
- Affordable cost.
The disadvantages will be:
- The presence of a "memory effect".
- High level of self-discharge.
- Great weight and size.
- Special disposal required due to presence of cadmium.
Features of NiMh batteries:
- More power density, so they have less weight and dimensions.
- The service life depends on the depth of discharge, so that the battery lasts longer, it is better to operate it not with a full, but with a surface discharge.
- Charging cannot be carried out as quickly as in the previous version.
- The "memory effect" is much less pronounced.
- They have a small number of work cycles.
- High self-discharge, which reaches 30% per month.
LiIon batteries have the following advantages:
- Small weight and dimensions, this is achieved due to the high density of electricity.
- Slight self-discharge.
- They do not require any maintenance during their entire service life.
The disadvantages of such batteries are as follows:
- High price.
- These batteries should only be stored charged.
- Even if they are not used, the aging process takes place, after two years, if they are not used, they usually fail.
LiPol devices are the most modern, but so far they are not widely used, so it is not yet possible to objectively assess their advantages and disadvantages.
When compared with other types, such devices have fewer duty cycles, and they are designed for not high current loads. The technology of their manufacture allows you to create thin and plastic geometric shapes, which is not typical for other types of batteries. As with everything new, the cost of such batteries is still high.
Now in electronic devices NiMh and LiIon batteries are mainly used. The first will have longer term service at moderate loads and lower cost, the latter have simple maintenance and a long service life under heavy loads. Nickel-cadmium devices are practically no longer used, and lithium-polymer devices are only gaining market share.
One of the most important components of electrical equipment and equipment of any type is a battery, or, more simply, a battery. There are different types of batteries, and in this article we will talk about all types of such devices.
The very first battery was created more than a century and a half ago in France by the scientist Gaston Plante. With each subsequent attempt to improve the devices, they got better, but the principle of their functioning and structure remained unchanged. Now there are a wide variety of types of batteries: Li-Ion, Ni-MH, Ni-Cd and many others. They are about the same, but each has its own characteristics. It is worth talking about all these varieties in order.
Antimony-reduced devices
Perhaps it is worth starting the description with one of the most commonly used types of batteries. Batteries containing less than 5% antimony eliminated the need for frequent additions of distilled water. Although this does not make batteries of this type maintenance-free due to the existing fluid flow.
They also have an extremely low degree of battery self-discharge and tolerance of the electrical characteristics of an automotive onboard network, unlike their newer counterparts.
antimony batteries
This type of battery is considered obsolete. He was replaced by more modern and improved types of batteries with a low antimony content. However, until now, batteries of this type serve their intended purpose in stationary current sources with unpretentious batteries.
Calcium Alternatives
Calcium batteries are good in that they reduce the intensity of electrolysis and lower the electrolyte level. In addition, calcium, which replaced antimony, increased the voltage needed to start electrolysis, which reduced the criticality of the effects of overcharging.
But do not forget that, like all existing types batteries, calcium batteries have their own weaknesses. The main disadvantage is that increased sensitivity to a powerful discharge leads to sharp drop containers.
Alkaline batteries
They call such devices in which alkali acts as an electrolyte, and not acid. Devices of this kind are found in cars far from common, but they can act as batteries, for example, for screwdrivers.
One of these devices is Ni-cd battery- in fact, it was recognized as obsolete, however, it can still stand on a par with its newer competitors due to its cheapness. However, the so-called "memory effect" and increased self-discharge make the use of Ni-Cd devices very problematic.
Its nickel-metal hydride competitor is, of course, higher in price, but at the same time it is much better in quality. Compared to Ni-Cd analogues, the "memory effect" is expressed to a lesser extent, although it is still present. Also, the increased capacity and reduced self-discharge fully explain the high price.
Li-ion alternative
Perhaps of all existing species batteries for cars and not only the best can be called Li-ion. It costs significantly more than its Ni-MH and Ni-Cd counterparts. This can be explained by the fact that batteries with lithium ions do not have the disadvantages that the models considered earlier have. Although devices of this kind, as well as all existing devices, are still not without their weaknesses and indeed significant.
The main vulnerabilities include:
- excessive sensitivity to low temperatures, which reduces the current sent by the li-ion battery;
- decreasing capacity every year;
- lithium-ion devices do not withstand total discharge and charge to the end - otherwise it ends in the destruction and even explosion of the device.
Models of this type are widely applicable as a charger for mobile devices. In the event that technological progress reaches a sufficient level so that Li-Ion devices lose their vulnerabilities, they will be able to replace acid batteries.
It is also worth noting that in older models a variety of lithium oxides were used, which also contained manganese or cobalt. However, these elements were no longer added to newer models, replacing them with lithium-ferro-phosphate alloys due to their low cost, reduced toxicity, and easier processing.
Lithium polymer batteries
Lithium-ion polymer battery, also known as Li-Pol, LiPo, Li-polymer, is an improved version of the standard lithium battery and is used in many types of technology. The electrolyte here is a polymer material.
Such types of lithium batteries are good in that they have a significant energy density per unit volume and mass, reduced self-discharge, extremely thin cells (from only 1 mm), the possibility of flexibility, an extremely insignificant voltage drop during the discharge process, a wide range of temperatures at which the device will continue your full-time job. And, on top of everything else, LiPo has no memory effect.
Although you should not blindly believe that batteries of this kind can actually be called completely ideal. Even Li-Pol has its flaws. One of the most significant is the risk of fire in case of overcharging and excessive heat consumption. The disadvantage is also a relatively small number of operating cycles - 800-900, as well as the aging of batteries, even if they lie aside unnecessarily.
Finally, even the charging itself has a very detrimental effect on the device: if the charging process reduces the capacity, then with a deep charge, the device can be safely sent to scrap metal.
AGM and GEL batteries
As they are often called, they acted as Alternative option safe to use. The safety problem was solved by moving the electrolyte into bound state to provide a reduction in fluidity.
Other advantages of GEL batteries are:
- reduced shedding of the active mass of the plates;
- reduced self-discharge;
- vibration tolerance.
They can also be tilted at almost any convenient angle, they can be stored for quite a long time due to slow self-discharge, and over-discharge is not "fatal" and does not cause any damage to the technology in the process.
But recharging a device of this type, on the contrary, can have an extremely negative effect on it. Therefore, GEL batteries still require very careful and careful handling.
Eg:
- despite the fact that they can be placed almost anywhere, they cannot be kept upside down;
- operation at low temperatures can drastically reduce the functionality of devices;
- Special precautions are required due to the special sensitivity of charging devices.
With reliable storage of the device, it can last up to ten years.
hybrids
The name speaks for itself: those batteries are considered hybrid, the structure of which includes unequal plates, that is, made of various materials. It is worth considering that positively charged plates include antimony components (its content in them does not exceed 5%), while negatively charged plates contain calcium components.
A new, almost revolutionary method of manufacturing batteries could lead to the following:
- First, if we compare antimony-reduced batteries, the fluid consumption is obviously reduced.
- Secondly, the battery has become more stable and resistant to voltage drops, even in cases of intensive charging and total discharge.
Of course, this does not mean at all that these batteries can be considered completely ideal "without a single flaw." They do not have any special advantages over all the above devices. But at the same time, in terms of the quality of their characteristics, they can be put right in the middle of this row.
Nickel metal hydride
Nickel metal hydrides, or Ni-MH as they are abbreviated, are types of batteries where the negative ion is a hydrogen metal hydride electrode, potassium hydroxide is the electrolyte, and nickel is the positive ion.
There is a considerable number various types Ni-MH batteries. For example, there are batteries long storage LSD NiMH, which is not afraid of frost and long term storage. They also function with increased discharge currents, without breaking or becoming unusable due to excessive load.
Therefore, for example, AA size nickel-metal hydrides can be used in various types small technology. So, AA with a large capacity of 1500-3000 mAh can be placed in a music player, radio-controlled toys, a camera and many other devices, where charging will be done in a relatively short time.
AA batteries with a reduced capacity are also very good - such AA batteries, where the capacity is only 300-1000 mAh. AA of this type are applicable as a power supply for non-automatic flashlights, toys controlled by the remote control, walkie-talkies and electronic devices with balanced power consumption.
It became the first invented battery that saw the light and found wide application in cars and a number of other technical devices.
The device got its name due to the lead plates lowered into water and sulfuric acid, which act as electrodes, although over time hydrogen in the device begins to be lost.
Such devices gained popularity not by chance, but due to obvious advantages:
- no memory effect;
- the presence of unattended instances;
- low price;
- simple design;
- reliable technology;
- reduced auto-discharge;
- potential for increased current output.
Although, despite a considerable number of advantages, even these models have their weaknesses:
- impossibility of storage discharged;
- excessive sensitivity to temperature changes, affecting the duration of functionality and life;
- limited transports and permitted whole discharge cycles;
- and, of course, the most obvious flaw - the detrimental effect of lead on the environment.
Nickel-iron analogues
Cheap and low maintenance Ni-Fe, aka nickel-iron batteries, have nickel oxide-hydroxides used as positive plates. Ferrum oxides-hydroxides act as negative plates. The liquid electrolyte appears as corrosive potassium.
It is worth recognizing that given type battery is very reliable due to its endurance to total discharges, frequent recharging. Unlike the same lead-acid alternative, such batteries will not fail when undercharged.
Good afternoon to all newbies. Today we will talk about voltage batteries. Batteries are chemical current sources in which, as a result of reversible chemical reactions, internal energy is converted into electrical energy. It is because of the reversibility of this reaction that batteries can be charged and discharged. Batteries are designed to accumulate electric current and are widely used in various fields. Without them it is difficult to imagine our life, they surround us everywhere. designed for repeated use and have a sufficiently long service life. The simplest battery- These are two electrodes that are made of different metals and are absorbed into an electrolyte (acid) solution. One of the electrodes is called the cathode and the other the anode.
In practice, lead and lithium batteries. The lead accumulator is made of two lead plates which are absorbed in sulfuric acid. Batteries have different voltages, for example, one block (bank) of a lead battery gives a voltage of 2 volts, one block of a lithium-ion battery - 3.7 volts, - 1.2 volts. Alessandro Volta is considered the creator of the first battery (from his name the value of voltage was formed - volts). Voltaic pillar had simple design- copper and zinc mugs, and between them a piece of watt soaked in a solution of water and sodium chloride. Today there are a huge number of varieties of current batteries, a complete list of them is given at the end of the article.
Batteries are made different capacities and voltage, depending on the consumption of the device for which they are intended. Battery voltage is measured in volts, current in amps, and power in watts. For example, if it is known that the battery current is 10 amperes / hour, and the voltage is 6 volts, and you need to find out its power, then according to Ohm's law we get 6 volts * 10 amperes = 60 watts. Thus, knowing two parameters, you can easily find out the third one. There comes a time when the battery runs out. As the chemical energy is depleted, the battery voltage and current drop, and the battery stops working. You can charge the battery from any source of constant or impulse current. It is considered standard charging current in 1/10 of the nominal capacity of the battery (in ampere / hour).
Discuss the article TYPES OF BATTERIES
The automotive battery (abbreviated as battery) is one of the most important elements vehicle. battery is a type electric accumulator used on cars or motorcycles. It is used to start the motor, as well as in the on-board network as an auxiliary source of energy during idle engine. In winter, the issue of battery reliability is key. In the cold season, the ease of starting the engine depends on the condition of the battery. And if the battery is old, plus there are severe colds outside, the car owner has stable troubles with starting the engine. Endless home recharging of the battery and, consequently, the shorting and shedding of the plates. All this is too troublesome for any, even the most hardy driver. Therefore, most car owners prefer to take care of a new battery in time. There are several types car batteries. They are all quite different and it is not so easy to choose the one that is most suitable for your car. More on this later in the article.
Unfortunately, when purchasing a new battery, most car owners believe that the more expensive the battery, the more reliable and better it is. To some extent, this statement is correct, but not one hundred percent. The problem is that there are different cars and different types of batteries. Naturally, each of them is designed for certain operating conditions. And if you do not take this into account, it is likely that after buying even the most expensive battery, you will again have to buy a new power source for your car.
The main characteristics of a car battery are rated voltage and rated capacity. Rated voltage - an indicator of the voltage at the terminals of a charged battery after charging is completed. For car batteries, it is six or twelve volts. The second indicator indicates the amount of electrical energy that the battery must have for a certain time. It is measured in ampere-hours, and its value is indicated when the battery is designated.
Each manufacturing plant must carry out the marking of automotive batteries, which gives all the necessary data about the battery. So, the first digit in any case indicates the number of battery cells, which can be three or six. Depending on this, the nominal voltage of the battery will be 6 or 12 volts. Then come the letters ST, which stand for starter. The next number indicates the rated capacity of the vehicle.
In addition, the marking of the battery contains additional data. "A" indicates the presence of a common cover. "Z" says that the battery is flooded, if such a letter is not in the designation, then this is a dry-charged battery. The following letters give data on the material from which the case is made: "T" - thermoplastic, "E" - ebonite. If you see "M", then the separator is made of PVC, and the letter "P" indicates the presence given element from polyethylene.
battery types
Automotive batteries can be divided into three main categories: maintenance-free, partial service and serviced.
The latter are extremely rare. The case of such batteries is made of ebonite, and the outside is sealed, for example, with mastic. In serviced batteries, you can replace any elements.
Low maintenance batteries are the most common. They do not need special maintenance and care. It is only necessary to maintain the desired electrolyte level and control its density. It all depends on what materials the battery electrodes are made from. Usually they are made from lead with a minimum admixture of antimony.
Maintenance-free batteries do not require any human intervention during the entire period of operation. They use a special design of the condensing system and plates. To date, these batteries are considered the highest quality, so the prices for them are quite high.
Maintenance-free batteries can be divided into two types - calcium and hybrid.
Calcium batteries are the most expensive, the electrodes are made from a lead and calcium alloy with an admixture of tin, aluminum, and, in some cases, even silver.
Hybrid batteries are more primitive - the negative electrodes contain potassium, and the positive plates are made from lead with a small part of antimony.
The use of calcium significantly reduced electrolyte evaporation, and also increased the service life of batteries - hybrid up to five years, calcium up to seven years. Self-discharge in comparison with low-maintenance batteries slowed down by one and a half times.
However, calcium durable battery poorly withstands absolute discharge. If it is completely discharged several times, calcium sulfate forms on the positive plates, causing the car battery to lose capacity.
Therefore, in hybrid batteries, calcium is used only in negative electrodes who are not afraid of discharge. The hybrid battery features a long service life, low starting current and high capacity.
In addition, batteries differ in technologies that are used in production:
Battery device
A battery with a nominal voltage of 12 volts, as a rule, consists of six cells that are autonomous from each other, which have a lower voltage (two volts). They are assembled in one housing and connected in series.
The principle of operation of the battery is quite simple. When a load is connected, charged particles begin to move in the battery, as a result of which a current appears. When charging from a charger or generator, the charge voltage is much higher than the battery voltage, which causes the particles to move in the opposite direction.
Battery Reviews
Most car owners, before purchasing the desired battery model, without fail look at the reviews on the Internet about it. Undoubtedly, this is correct, as it makes it possible to obtain data about the product directly from the consumer. However, there important nuance! IN modern world it is no longer a secret for anyone to buy reviews for money, so such information is not always objective.
Based on consumer data taken from various forums, and on the personal opinion of many experts, the following conclusions can be drawn:
- Batteries of the Varta and Bosch brands have the same and quite high quality. The equipment on which they are made is made in Italy, the USA, Germany. Modern production of batteries takes place without human intervention, as a result of which we can conclude that the quality of charging, assembly, and plates is identical in all factories.
- Premium batteries Varta Silver and Bosch S 5 on average can last from six to eight years. And the average life of models such as Varta Black, Varta Blue, Bosch S3, Bosch S4 is approximately five years.
- A-Mega brand batteries can last up to six to seven years.
- IN this list it is worth highlighting the batteries that belong to premium lines worldwide famous companies- Delkor, Varta Silver, Bosch S5. There is an opinion that they can last more than seven years.
- Average battery life price segment(Mutlu, Westa, Ista) is three to five years.
- Batteries from unknown manufacturers typically last about one to two years. Reviews about them are the most negative, so it is better to protect yourself from such purchases.
Most of modern batteries well-known manufacturers, even cheap ones price categories, serve about four years. Premium batteries last even longer. Naturally, the operating conditions of the battery, as well as caring for it, also affect the battery life.
How to choose a battery, the best batteries
When choosing a battery for your car, there are a few things you need to know. important parameters that the battery should have:
- Small voltage drop.
- Small self-discharge during operation.
- The ability to deliver high current.
- Small dimensions.
- Minimum maintenance.
There are seven main steps before purchasing a battery that will help you make the right choice:
It is impossible to unequivocally answer the question of which battery is the best, since any battery has positive and negative sides.
A few tips for battery maintenance and operation:
Electric battery – special device, accumulating electricity and providing autonomous power to the equipment. During its operation, there is a transition of one type of energy to another, as well as the reversibility of the described process.
In most cases, the electrochemical method is used. Among the names of an electric battery is a secondary chemical source current, as it must be charged before use.
Battery types
By type, batteries are divided depending on their chemical composition, which affects their performance properties.
- nickel-cadmium (Ni-Cd) - the most old type rechargeable batteries, is distinguished by the need to comply with the “full discharge” - “full charge” cycle (they have a memory effect) and are sensitive to cold (they give off energy poorly in cold weather), but they can be stored overwhelmed and have a low self-discharge, are now used mainly in power tools
- nickel-metal hydride (Ni-MH) - a very common type of simple and cheap compact rechargeable batteries, the memory effect and sensitivity to cold are somewhat lower than nickel cadmium batteries, but they need to be stored charged and have a higher self-discharge, they are now used mainly in radio telephones
- lithium-ion (Li-Ion) - more modern type batteries are almost not subject to the memory effect (decrease in capacity), which allows you to charge them at any time and it is not necessary to discharge them to the end, there is sensitivity to cold, but not critical, you need to maintain a charge during storage, they are often used in cameras
- lithium polymer (Li-Pol) - light version lithium-ion batteries, which has the same properties, but with a much lower weight, which has found application in compact mobile devices and drones
- lead-acid (SLA) - large powerful batteries capable of quickly delivering huge energy (amperage), which is used in engine launchers (starters) and uninterruptible power supplies, require periodic recharging during storage
Batteries also differ in voltage in volts (V), capacity in ampere hours (Ah) or milliamp hours (mAh) and physical size (size).
Battery classification
All batteries can be divided according to their purpose into several main groups:
- household (batteries)
- for radiotelephones
- for flashlights
- automotive
- for UPS
- industrial
Now let's look at them in a little more detail, including sizes and the best manufacturers.
To ensure the normal functioning of the equipment, batteries of different sizes are used. Their main area of use is the power supply of small household devices.
Rechargeable batteries are used for the most various devices- radio mice, keyboards, cameras, simple flashlights, watches, other small electronics.
They have different sizes:
- AA (finger) - the most common format of round batteries with a length of 5 cm, a voltage of 1.2 V and a capacity of 1000-3000 mAh
- AAA (mini-finger) - also widespread, have a length of 4.4 cm, the same voltage of 1.2 V, but a smaller capacity of 500-1500 mAh
- crown - a rarer rectangular battery with a voltage of 9 V, used in some electrical appliances (for example, multimeters)
There are other, rarer formats of rechargeable batteries:
- CS (Sub C) - short round battery
- C (R14) - medium round battery
- D (R20) - large round battery
They are not common and are used in some specific devices and old cameras.
The best popular manufacturers of rechargeable batteries include Panasonic, Varta, Ansmann, Sanyo. There are also many others famous brands but they are often counterfeited.
It can be a monolithic battery or individual elements. Such devices are small in size and light in weight. Cordless phone batteries are often convenient prefabricated Ni-MH rechargeable batteries.
Also, some phones use non-standard branded batteries. Of the manufacturers, Panasonic and Robiton can be recommended.
Flashlight batteries are available on the market in a wide range and the choice depends on the specific model.
The most popular are:
- AA (14500)– batteries for large flashlights (length 5 cm, diameter 1.4 cm)
- AAA– ordinary Ni-MH cells with a nominal voltage of 1.2 V and a capacity of 500-1100 mAh
- CR123A 16340– designed for compact flashlights (length 3.4 cm)
There are also special batteries for powerful flashlights and stun guns.
They have their own unique sizes that need to be selected depending on the flashlight model:
- 10440
- 18650
- 26650
These batteries differ in physical size and capacity. They are mostly lithium polymer, which makes them very light. Of the manufacturers, Panasonic, Robiton, Fenix have proven themselves well.
We will not talk much about car batteries, we will only touch on the differences from all the others that you need to know.
These are large serviced lead acid batteries with liquid electrolyte. They are able to quickly deliver a huge current, but it is necessary to monitor their charge and electrolyte level (top up if necessary). Keep lead battery discharged is impossible, because somewhere in six months it will fail.
Batteries for computer UPS are designed to provide non-durable power to equipment in the event of a temporary power outage. They are also lead-acid, but unlike automobiles, they are maintenance-free, and the electrolyte in them is thickened in the form of a gel, which prevents leakage.
Otherwise, these batteries are similar to car batteries, they can quickly deliver a large current and require periodic recharging. Different UPSs use batteries with different voltages (12 or 24 V), different capacities (7, 9, 12 Ah) and different physical sizes. There are also models in which several batteries connected together are installed.
Choose a battery of the same voltage and size as in your UPS, the capacity can be slightly larger if desired (for example, 9 Ah instead of 7 Ah) - this will extend the operation of the PC from the UPS. Of the manufacturers, SCB, Yuasa and Delta can be recommended.
Batteries in the UPS for a gas boiler and other critical equipment differ larger capacity compared to models used in the operation of computer equipment. After all, they are designed to maintain the functioning of heating devices for a day or more.
Such batteries are often external and are connected to the UPS using special terminals, and the UPS themselves must provide voltage in the form of a pure sine wave, which is important for electric pumps used in heating systems and other voltage-sensitive equipment.
Industrial batteries
Usually huge batteries large capacity. They can be of different voltages, including high voltage ones. We will not say anything more about them, since this is not the subject of our site.
Conclusion
In order for the battery to hold a charge well and last long enough, it must be from a reliable, trusted manufacturer and, of course, original, and not a cheap fake. It is also important in what conditions and how long the batteries are stored.
Therefore, it is best to purchase batteries in specialized stores that pay Special attention their quality. High-quality batteries for a variety of purposes from the best manufacturers can be purchased at https://voltacom.ru/catalog/power/akkum.
