The car calmly moved along the highway, but suddenly the battery starts to fail. It is difficult to continue operating the vehicle in such a situation, professional intervention is required complex mechanism. If you need to charge the battery, you can call an auto electrician directly to the place where the car stops. The specialist reacts instantly: he leaves in 5-15 minutes and gets to the customer of the service by the shortest route.
BENEFITS OF WORKING WITH PROFESSIONALS
Why is it more profitable to turn to the master, rather than trying to find a breakdown on your own? Everything is elementary: an experienced electrician will quickly find the cause of the battery malfunction, offer the best scenario for the development of events and carry out repairs himself. It may be necessary to replace the battery if the device has exhausted its entire working life and the restoration of its functionality is in doubt.
WHY DISCHARGE THE BATTERY?
Any vehicle may need to charge the battery. The reasons for the discharge are different:
1) Long work optics (headlights);
2) the perimeter was on alarm for a long time;
3) breakdown of the generator, etc.
A field auto electrician comes to the site with his tool kit to identify the cause of the battery inactivity. In particularly difficult cases, the master explains the situation in detail to the owner so that he can make a decision. If changing the battery allows the car to continue on its way, the auto electrician can perform the procedure right at the exit point.
Battery: replacement or charge
No matter how much you turn the key, the car will not start, only the starter is buzzing, turning the parts. The reason is a discharged battery (battery). True, they do not fully believe: the car drives regularly, the electrical system is working. So the battery needs to be charged.
Should only at first glance. Car batteries in the cold rapidly lose capacity, and when the electrolyte is strongly cooled, they do not accept a charge.
For the urban motorist, the situation turns into difficulties. When driving on the streets, with frequent starts and stops, the load on the battery increases dramatically. The intervals of engine operation are insignificant, the battery does not have time to warm up and charge.
Of course, you can bring the battery home for the night. But the car is in the parking lot even during the working day, and there is no desire to carry the battery to the office and back, and colleagues will not understand.
So the driver gets two decisions, either charge the battery or replace it.
You need to charge the battery if:
The battery is operated at low or high temperatures;
the battery was bought recently, but there is not enough current to start the starter / engine;
the car is used in urban driving by 80% or more;
the car is often and/or left out of the garage for a long time;
after parking for a day or more.
If the battery fails to “revive” by charging, there is only one way out: replacement. Strictly speaking, there are a number of parameters that indicate the imminent failure of the battery. Several characteristics and features are of practical importance.
The battery needs to be replaced if:
stains, streaks were found on the battery case;
The battery is slowly charging;
the battery is quickly discharged, even at rest;
part or all of the battery is heated at rest;
when charging, the battery case is hot in one or more places;
a specific acid smell is heard under the hood and / or in the cabin.
Let's explain a little. Typically, car batteries are charged with a current of 5% of the nominal capacity. The process lasts about several hours, depending on the capacity and device of the battery. In this mode, a long battery charge is considered to be more than 20 hours. Modern batteries can be charged at higher currents and with less time. The procedure for charging unattended batteries is usually very different even between the batteries within the same model. The procedure time is indicated in the instructions.
Rapid discharge, even at rest, prevents the use of the vehicle's electrical appliances while stationary. If after an hour of listening to the radio the car does not start, but the battery was charged a few days ago, you need to change the battery. It is advisable to check the electrical circuits
One of the main parameters of battery service is age. During the operation of the battery, sulfates are deposited on the plates, some of the compounds precipitate. The battery plates are destroyed, the supply of current is out of the question.
Premium series batteries from leading manufacturers, such as Bosh or Varta, are designed for 8 to 10 years of operation at regular maintenance. Regular series batteries famous brands designed for 3 - 5 years of operation, but with constant maintenance and good conditions maintenance of the machine are used up to eight years. Batteries from unknown manufacturers are truly a pig in a poke. Assembled in China, they can last for years, but usually work time is limited to a couple of months. The only plus is low price comparable to the cost of several gas stations.
You should not expect the impossible: batteries that work stably for decades are not produced for cars. In the process of using the battery, chemical processes lead to a loss of capacity and voltage. Processes are irreversible. On average, the battery loses about 5% - 7% of capacity per year; during battery operation fixed-route taxi capacitance loss increases. Sometimes up to 15% - 17% per year.
Choosing a replacement battery
Owners Soviet cars accustomed to the unpretentiousness of steel horses. But even “omnivorous” in terms of batteries, relics are important for capacity, service life and backup current. Due to the structure of batteries, capacity is directly related to weight and charge speed. If possible, choose a battery with the largest available capacity. Full charge takes a lot of time, but when used on cars high-capacity batteries last longer and cause less trouble for owners, they tolerate frost and heat better.
The battery life is indicated in the instructions, the average parameters are indicated above.
Reserve current is usually indicated on batteries made in the USA. The indicator tells how long the battery will last if the generator fails.
Modern batteries with alloy plates are less prone to plate failure, charge faster and weigh less. But only products of well-known companies meet the declared characteristics.
Modern smartphones perform a lot of functions. They became for us indispensable assistants. With a conventional device, you can easily navigate the terrain using GPS module, use high-speed internet, take photos High Quality, play productivity games and more. Of course, all this has a bad effect on the battery: it starts to discharge faster, the battery lasts less and less.
So it turns out that after a few years you have to change the battery. Now we will look at how the battery is replaced on the iPhone 5 and how to understand when to carry it out.
Decrease smartphone battery life
If you notice that your iPhone 5 phone has begun to discharge faster, then this is the first signal that the battery will soon need to be changed. Remember that your smartphone should not lose more than 1% of its charge at one time. Of course, if you do not play "heavy" games. You can monitor this in the settings by going to the battery statistics.
Also, your device should not spontaneously turn off when the battery is 20-30%. This behavior of the phone clearly indicates a battery failure. In this case, the battery must be replaced on the iPhone 5.
Viewing Battery Status Programmatically
The iPhone 5 is a fairly high-tech smartphone equipped with special programs, which are able to count battery charge cycles. This feature allows you to monitor the battery capacity. Unfortunately, this data cannot be viewed in the settings - they are available only to Apple employees.
An ordinary user can control the battery using the iBackupBot program. All you need to do is connect your iPhone to your computer, run the program, and ask for all the battery data. The utility will establish a connection between the computer and the device and show the number of charge cycles, the current state of the battery, its initial volume. If the original battery capacity is noticeably different from the current one, the battery should be replaced. In general, the phone can work well until it exceeds 500 battery cycles.
Replacing the battery on the "iPhone 5"
If you decide to replace the battery yourself, you will need a TS1 screwdriver, a suction cup, a plastic case removal tool, and a PH000 screwdriver. Before starting work, you must turn off your smartphone.
It should be noted that the Chinese "iPhone 5" outwardly does not differ from the original. Therefore, the replacement of the battery will be carried out almost identically.
Battery for iPhone 5
If you plan to replace the battery yourself, then you must first buy a battery. The original battery can be purchased online for only 1000 rubles. Of course, you will first need to make sure that it will fit, and only then make a purchase.
Service centers
If you do not dare to replace the battery yourself, you can contact service center. Everyone knows how much the iPhone 5 costs - it's quite an expensive phone. Therefore, battery replacement and repairs in general will be quite expensive. On average, they ask for 1600 rubles for a battery replacement. This price includes the battery itself and the services of the master.
Conclusion
There is nothing complicated in replacing the battery. You only need to carefully and consistently perform all the steps. Beginners can spend quite a lot of time on a replacement, but this is necessary in order to qualitatively fix the problem. If you do not want to risk, then you should contact the service center. What is the price? "iPhone 5" masters can repair quickly enough, but it will take about 1600 rubles.
Very soon after the release of the “five”, the request “How to replace the battery on the iPhone 5 yourself” became incredibly popular. The reason for this "panic" quickly became clear, it turns out that Apple supplied one of the batches of the new smartphone with defective batteries. However, the "apple" giant did not pretend that he did not notice the problem and got out of the situation very beautifully, quickly organizing a program for the free replacement of buggy batteries around the world.
Today, this defective batch has long been forgotten, but the request is how to replace iPhone battery 5 with your own hands, if it has become less popular, then not by much. No, it’s not that the battery of the five is so unsuccessful, it’s just that the batteries of powerful modern smartphones wear out very quickly, because they are exploited, as they say, in full. At the same time, most flagship phones are now equipped with non-removable batteries, and replacing them is expensive - the iPhone 5, of course, is no exception. That is why, a modern advanced user really wants to learn how to change the battery on his device on his own.
Well, in this article we will tell you how the replacement is performed iPhone battery 5, and you, having assessed the degree of complexity of the procedure, will be able to decide whether to take up the matter yourself or better turn to the pros.
On a good note, the battery replacement on the iPhone 5 smartphone should be done once a year, in which case it will give out the autonomy promised by the manufacturer. However, if you are ready to measure with some of its decrease, you can carry out the procedure less frequently. However:
- if the smartphone began to be discharged at the same time by 2-3% or more
- if the device turns off at a charge level of more than 20-30%, and when you try to turn it on, it displays a screen indicating that the battery is low
- if the display began to move away from the case a little or cracks appeared on the device
It's definitely time to change the battery!
It is worth noting, however, that the last sign may indicate other malfunctions, but if you have not dropped your smartphone, then most likely the case is bursting the battery. How so? The fact is that in the course of its work, the battery emits gas - it accumulates under the shell and slowly inflates it.
When the "life" of the battery comes to an end, there is already a lot of gas, and the shell swells so much that it can easily damage the case or the display of the smartphone.
Required Tools
Getting ahead of the curve, changing the battery on an iPhone 5 is not a very difficult procedure, but if you are doing it for the first time, you will need special tools to parse Apple technology. Pros, as a rule, cope with universal tools.
You can buy them in the same place where you will buy a new battery. If you are not in a hurry to replace, the most profitable, of course, is to order a battery through an online store - Aliexpress or Ebay, and, by the way, very often batteries are immediately equipped with everything necessary for replacement - this is very convenient and not much more expensive.
Carefully check that the set should contain:
- two screwdrivers - type Pentalobe + Phillips
- sucker
- plastic spatula
However, if you need to change the battery urgently, and there is no time to wait for delivery, go shopping at the nearest store selling electronic parts.
How to replace ABA on iPhone 5: instructions
Well now it's time to bring you detailed guide on replacing the battery in the iPhone 5. By the way, the instructions below are also relevant if you need to replace the iPhone 5S battery and replace the iPhone 5C battery, because all fives have a very similar design.
So, how to change the battery on iPhone 5/on iPhone 5C/on iPhone 5S:
1 Turn off your iPhone first. 2 We take a Pentalobe screwdriver and unscrew the two screws - to the left and to the right of the power connector.
4 As soon as all the latches are unfastened, we raise the display and fix it with some improvised means. 
7 Raise the gasket, and then, one by one, unfasten the three loops. 
11 The deed is almost done! It remains to put your new battery and follow all the steps in the reverse order - we arrange all the cables as they should and fix them metal gaskets, connect the screen and the case with latches, tighten the screws at the connector. Ready! Now let's turn on the iPhone and see if everything is in order. We hope everything worked out for you and the device will work fine with the replaced battery.
Let's summarize
This is how the battery is replaced on the iPhone 5 smartphone (remember, the iPhone 5C battery is replaced and the iPhone 5S battery is replaced in the same way). Now you can draw conclusions - is it worth turning the procedure on your own or is it better to contact the service.
The resource declared by manufacturers car batteries averages four to seven years. To avoid possible problems When a battery fails, it needs to be changed in time. The replacement process consists of two stages: the preparation stage and the operation itself.Before replacement
The first step is to find the battery. Depending on the design of the vehicle, the battery may be different places: under the hood, in luggage compartment or under the seat in the cabin. Exact location indicated in the vehicle's owner's manual.
Next, you need to find the exact markings on the battery case. This information will be needed in the future to purchase a new battery.
The third point of preparation is the selection of devices with which the dismantling will be carried out. Add to list the right tools includes:
- wrenches and socket wrenches for 10 and 13 for removing terminals and battery holders, respectively;
- fine-grained sandpaper and a metal brush for cleaning oxidized contact points between the terminals and the battery;
- acid-resistant gloves;
- rags to clean the shelf on which the battery is installed.
Procedure for replacing a car battery
For the safe dismantling of the old battery First you need to remove the key from the ignition system.
Next, the terminals are disconnected. To avoid short circuit from an unintentional touch of the positive wire with the car body, the negative terminal is removed first, and only then the positive terminal. Polarity is determined by color. A black wire always goes to the negative terminal, and a red wire to the positive terminal.
After that, the nuts of the retaining fastening are loosened, and the battery that has become unusable is pulled out of the seat.
Before installing a new battery, the contacts must be cleaned of possible oxide and rust, and the place where the battery will fit is thoroughly cleaned with a rag.
Installing a new battery is done in reverse order. It must be put in the same place, secured with retaining nuts. Twisting them, you can not apply excessive force, so as not to violate the integrity of the battery.
Connecting the battery starts with a red wire going to the positive terminal. The black wire, respectively, is attached to the negative. The correct connection of the wires is also facilitated by the fact that the terminals of different polarity differ in diameter. The wires must be connected to the terminals securely, creating a strong contact.
It is not clear why the unforgettable Alexander Sergeevich Pushkin loved autumn: it's a rather nasty time. And winter would soon come with sparkling and crunchy snow underfoot and a light frost. It’s just that during this period we will have to operate not a horse harnessed to firewood, but stuffed with electronics and very capricious to voltage drops in onboard network automobile. And how joyful the morning will be, largely depends on the condition of the battery.
by the most important indicators battery are its electrical capacity and cold scrolling current (or starter discharge current). The battery capacity is designed for the conditions of ensuring a positive energy balance for a given cycle of operation of electrical equipment specific car. If the capacity of the selected battery is insufficient, the depth of its discharge when starting the engine can be 40–60% or more, and systematic deep discharges of the battery will inevitably lead to a reduction in its resource. But with the battery larger capacity than you used before, the story is reversed: the depth of its discharge will be less than that of a standard battery, and the generator can easily cope with the charge of your new battery about 3-4 minutes when the car is moving from average speed 50–60 km/h.
But even here one should not overdo it: using a battery with a capacity significantly higher than recommended can lead to accelerated wear of the brushes and the contact surface. slip rings starter due to higher voltage discharge. Based on the design of your vehicle, when purchasing a new battery, you must consider dimensions, the shape of the conclusions, their location. Now about the choice of brands.
Modern technical level manufacturers of batteries of leading brands is approximately at the same height: the same equipment, raw materials and components are used in production. And if technological process is observed according to all the rules, then the efficiency of the batteries produced here is maximum. Are you tempted by the low price of the battery? There may be a catch: to reduce the cost of the battery, the simplest is to reduce the main component in the battery - lead. And this will immediately make itself felt: the starting power is not enough, the battery is quickly discharged and freezes, and thin lead plates crumble quickly. Such a battery will last you no more than a year. It should also be taken into account that battery wear increases many times due to deep discharges in winter and recharge in summer. The service life of such batteries is up to the first cold weather. At correct operation battery life is 4-5 years.
Basic condition uptime is the positive energy balance of electrical equipment on the car during its operation. This means that during the operation of the engine, the amount of energy supplied to the battery is equal to or slightly greater than what was given by the battery to start the engine and power the devices with a low output of the generator. That is, while the car is moving, the battery must always have an optimal charge.
In order to ensure a positive energy balance in modern cars, saturated with a large number of electrical consumers, they are equipped with control systems for the process of distributing generator power. Sometimes in winter, cars with such a system may suddenly refuse to work with seat heating, power windows, etc., which is sometimes perceived as a breakdown. Don't be alarmed: in such cars, the controller switches off the convenience devices in the car in steps, saving energy for starting the engine, operating the lighting system and windshield wipers.
A serviceable and well (75–100%) charged battery does not require constant attention from the owner vehicle and does its job reliably. But if at start-up the starter is in no hurry to turn vigorously crankshaft engine, do not rush to blame the battery for everything. It is possible that the amount of energy given off by the battery to the electrical system was not replenished from the car's generator, due to which the charge level, and therefore the battery's performance, decreased. If the battery raises doubts (the warranty period for which has not yet expired), then there is a reason to contact the brand's service center.
There may be other reasons for the battery level to be low. This is a malfunction of the electrical equipment of the car, and the installation of additional energy-intensive consumers, the power of which exceeds those recommended for this car ...
But sooner or later it's time to replace the battery. The procedure is simple, but its sequence is important. When removing the wire terminals from the battery, you need to remember that you first remove the “minus” and then the “plus”. With this sequence, we exclude the possibility of a short circuit. By the way, if the battery is not provided protective cover, then the positive terminal must be protected with insulating material.
Before installing a new battery, clean the terminals of dirt with an alkaline solution. Unusual deposits must be removed from the terminals, and then washed with distillate. However, you cannot use plain water, as this will lead to the formation of salts. After the terminals are cleaned, they must be thoroughly wiped with a rag and treated with a special anti-corrosion agent. The terminals are attached to the battery in the reverse order of their removal: first, the positive terminal is mounted, then the negative terminal.
And one more important thing to remember when replacing the battery: disconnecting the battery resets all settings on-board computer and other sensor data. This is the problem, because reverse installation battery does not return whole line former electronic settings vehicle functions. For example, if the radio has a code, then for its subsequent launch, this code will need to be entered.
