The size of the battery for a car is of great importance when buying. In a modern car, a limited space is allocated for the battery, and if you choose it incorrectly, you will either not be able to install it in a regular socket, or you will not be able to connect the terminals, or simply will not close the hood.
When choosing a battery, in addition to technical criteria, you should pay attention to four important characteristics - the dimensions of the battery itself, the location and size of the terminals, and the polarity of the battery.
Battery dimensions
It is believed that all batteries are standardized in size, which simplifies their installation in a regular socket on a car, but there are several of these standards - European, Asian and American.
- American- Suitable for US vehicles only. In the "American" battery, the terminals for the terminals are located on the side surface of the top cover and have an "internal" thread. These batteries are not compatible with European and Asian type terminals.
- European standard(175-242 x 175 x 175-190 mm or 278-518 x 175-240 x 175-242 mm) - designed for any cars of European and domestic production. The terminals are flush with the top cover of the battery case.
- Asian (JIS)- used in cars of Japanese and Korean stamps(187-261 x 127-175 x 190-227 mm or 306 x 173 x 225 mm). The "Asian" battery is narrower and shorter than the European one, but higher. In addition, the terminals here are located on top cover, which should be taken into account: if for "Japanese" and "Koreans" this is an acceptable format, then for European cars it is unacceptable - it is possible that the terminals cannot be connected.
Battery mount type
When choosing, be sure to pay attention to the type of battery mounting in a regular socket: the battery can be mounted from below or from above. In batteries for the bottom mount, there is a small protrusion on the bottom of the case, and the top mount is carried out using a special mounting frame that surrounds the battery.
This important characteristic, since the battery in the socket must be firmly fixed - the battery does not like vibrations and quickly fails for "amateurs" to ride with loose battery(on impact, the case can crack and the electrolyte can leak out).
Terminal size and shape
Electrical outputs for terminals different batteries it may also differ what you need to pay attention to so as not to have problems later with connecting the battery to the power supply.
- All domestic and many foreign batteries have cone-type terminals (the positive contact has a larger diameter than the "mass"). On some batteries, the conclusions are made “for a bolt” (trucks) or a screw (American type of battery).
- The diameter of the conical contacts can be standard ( domestic cars) or small (for Japanese cars).
- If the shape of the terminals and the output contacts of the battery do not match, you must either replace the contacts or purchase a suitable set of adapters.
- In some models of Asian cars, the "+" terminal has a massive design, and connect it to the terminal European battery impossible
Polarity, i.e. the location of the current-carrying contacts, the battery is of great importance for connecting the battery to the terminals. When not right choice and connection, you risk getting short circuit or burn all the electrical wiring of the car.
Polarity batteries can be direct ("+" is on the left) or reverse ("+" is on the right). The first option is typical for connecting batteries in cars Russian production, the second - "European standard" for foreign cars.
For normal operation of the car's electrical system, it is necessary to ensure its reliable connection with the battery - this is provided by special terminals. All about battery terminals ah, their types, design, features and applicability, as well as their correct selection and installation, read the article.
What is a battery terminal?
(accumulator battery, starter battery) - an electrical product for automotive and tractor purposes; large cross-section terminal for connection onboard network vehicle (TC) to the battery (starter) battery terminals.
Battery terminals perform several functions:
- Electrical connection of the battery with a starter, generator and other current consumers, as well as with the "mass" of the vehicle;
- Possibility of quick assembly and dismantling of standard and suitable this car rechargeable batteries;
- Ensuring reliable electrical contact during active operation of the vehicle in various conditions;
- Protection against incorrect connection of the battery and (sometimes) short circuit.
It is from the battery terminals that the on-board electrical system of a car, tractor and other equipment begins, therefore their quality, reliability and reliability play an important role. electrical characteristics. In the event of a malfunction, the terminals must be replaced, and in order to make right choice of these details, it is necessary to understand in detail their types, design, features and applicability.
Types and design of battery terminals
Battery terminals differ in applicability, design, material of manufacture and some features.
First of all, products can be divided into four classes according to the method of installation and, accordingly, applicability:
- Knife type "mother" - for connection with batteries equipped with knife terminals;
- Screw - for connecting to batteries that have various types of flat terminals with a hole for a screw / bolt;
- Cap - for connection with batteries that have cylindrical or conical terminals;
- Universal screw and cap - for connecting to batteries equipped with cylindrical or conical terminals with a transverse hole.
The most widely used in autotractor technology find captive terminals - in the future we will talk about them. Although a lot of what has been said about the terminals is true for screw and universal terminals (this applies to the material of manufacture, the method of connection to the wire, etc.). We also point out here that knife terminals are used to connect low-power batteries (including those on motor vehicles), and screw terminals are used on some foreign-made cars, small boats, etc.
Slip-on terminals, regardless of type and applicability, have a fundamentally the same device. This is a one-piece or composite part that has a loop or clip on one side for mounting on a terminal, and on reverse side- a tip for connecting to a wire.
Terminals can have a cap various types:
- Ω-shaped bracket - made in the form of a clamp, on the back of which there are screw holes for fixing the terminal and mounting the wire;
- Bracket with transverse screw clamp - a bracket with a bolt / screw with a nut located in the front, which fixes it on the battery terminal;
- Bracket with longitudinal screw clamp - a bracket with a screw located on the side.
According to the design of the tip, the terminals are divided into two groups:
- With clamping (screw) tip;
- With compression (crimp) tip.
Tips of the first type are various options screws with nuts, screws with clamping bars and screws located in channels. The end of the wire is fixed in the lug by pressing one or two screws / bolts - this is the simplest solution in design, which allows you to remove and replace the wire without the use of a special tool.
Tips of the second type are made in the form of a deaf short tube into which the end of the wire is inserted and crimped. Such a tip has its own difficulties and features of installation (it is quite difficult to evenly and efficiently crimp the wire without having the skill), but it provides the most complete contact with the wire.
In this case, the tips are of two types according to the number of connected wires:
- One or two wires - one starter and one generator, one to ground;
- Three or more wires - additional wires for connecting individual current consumers.
Usually the extra wires are small, so they are connected to the reduced size lugs.
Battery terminals are made from various materials: lead, brass and bronze, brass with tin-bismuth coating, copper, aluminum, copper-plated zinc and others.
Lead terminals. They are made of lead, have steel clamping screws/bolts and other parts. They are most compatible with lead terminals on the battery, but they have increased electrical resistance and, when the battery is discharged, can degrade the operation of the electrical system. In addition, lead terminals have low mechanical strength and are intensively destroyed under the influence of negative factors. environment.
Brass and bronze terminals. They are made of brass and bronze of certain grades, have high mechanical strength and low electrical resistance. However, they have significant disadvantage- upon contact with a lead terminal, they form a galvanic couple, chemical reactions occur between dissimilar metals, leading to the formation of oxides on the surface of the terminals. As a result, over time, the contact between the terminals deteriorates, and they themselves are destroyed.
Brass terminals with tin-bismuth half. They are made of brass and have a continuous coating of tin-bismuth or other solder, which reduces the intensity of chemical reactions when installed on a battery and extends the life of the product.
Copper terminals. Best Solution in terms of electrical characteristics, since copper has a high electrical conductivity and practically does not affect the resistance of the circuit at any current. However, they are characterized by all the disadvantages described above, so they are more often used copper terminals with coatings, including gold. These terminals are widely used today for car tuning - when installing powerful audio systems high class and other equipment.
Aluminum, zinc and other terminals with protective coating. This is not a very common group of terminals, they are light in weight, but due to the presence of a coating they are quite expensive and their installation is not always justified.
Battery terminals with plastic protection
For all battery terminals, various environmental factors pose a serious danger, therefore, for additional protection plastic or rubber covers, protective boxes and other devices can be used.
Battery terminals are divided into two types according to their purpose: positive (positive) and negative (negative). They are also divided into groups for Vehicle with voltage in the on-board network 6, 12 and 24 volts.
In conclusion, we point out that today there is a wide variety of terminals with additional functionality: with a built-in voltage indicator, special corrosion protection, screws for quick installation / dismantling, and others. However, in general, their design does not differ from that described above, so we will not consider them separately.
Dimensions and applicability of battery terminals
There are terminals on the market for various types of batteries, the most common are two standards:
- Euro (Type 1) - terminal "+" with a diameter of 19.5 mm, terminal "-" with a diameter of 17.9 mm;
- Asia (Type 3) - terminal "+" with a diameter of 12.7 mm, terminal "-" with a diameter of 11.1 mm.
The dimensions of the connecting tips of the terminals are calculated for wires with a cross section of 8-12 square meters. mm, but there are options for larger wires.
How to choose and replace the battery terminal
The choice of terminals should be made based on the type of battery installed, the operating conditions of the vehicle and the features of its electrical system.
First you need to determine the type of battery - "Euro" or "Asia", and select the terminals of the appropriate size. You can then select a terminal based on the number of wires connected to the ferrule—in most cases, the standard one-wire and two-wire terminals will suffice. If the car has optional equipment, you may need parts with the ability to connect three wires or more.
As for the metal for making the terminals, there are a lot of options here. The standard solution is inexpensive lead parts. However, to extend their service life, it is recommended to periodically check the strength of the installation and clean it from contamination. With a slightly larger budget, you can choose brass or bronze terminals, plain or with a tin-bismuth half. And when it is important to provide a high-quality connection, it makes sense to buy copper terminals, including those with a protective coating. Products of this group have a high cost, but their purchase will be justified.
The terminals must be installed in accordance with the manufacturer's recommendations. First of all, you need to clean the contact terminals on the battery and sand the inner surfaces of the terminals (especially if they are painted), during installation it is necessary to firmly tighten the screws and ensure secure fastening wires. After fulfilling all the conditions, you will receive a reliable electrical contact And normal work vehicle electrical systems.
Any part of the car requires control. The role of the battery in the operation of the car is one of the most important - if it fails, not only the auxiliary source of electricity disappears, but also the ability to start the engine. The car owner needs to regularly monitor the electrolyte level, its density, charge level, and recharge the battery when necessary. Contact terminals play an important role in the operation of the battery - electrical conductivity depends on them. We can safely say that they are subjected to the strongest destructive effect of the current, and therefore deteriorate more often than many.
Selection of terminals for the battery.
Basic information about battery terminals
A car battery stores energy in order to use it later to start the engine, operate headlights, wipers, and transmit current to all car electronics when the engine is not running. The vast majority of models use lead acid batteries. To choose the right battery, the material does not matter as much as other characteristics. Batteries are also selected according to the purpose of the application, the method of charging, and the possible additional functions. Naturally, when choosing a car, they do not attach special importance to a suitable battery, because there are more important and interesting characteristics. With all the variety of manufacturers, there are only a few criteria when choosing a battery.
Two types of devices can be distinguished: batteries that need to be serviced and those that do not need to be serviced. The fact is that in the first case, the car owner has the opportunity to replace failed parts during the operation of the device, but in the second case, the battery is sealed - it does not need to be regularly inspected or filled with additional water. The method of charging also plays a decisive role. There are charged and dry-charged batteries. The only difference between them is that for dry-charged ones, it is necessary to mix special components in complex proportions in order to obtain a liquid that is poured inside. So, if you don’t want to bother with difficulties, choose charged batteries. There are also special covers with a separation system. They protect the electrolyte from spilling out, and the water from excessive evaporation.
What are the terminals
most big problem in battery operation is the oxidation or destruction of the terminal. In this case, the terminals must be replaced. In the car market you can find devices made of lead, copper and brass.
lead
Most car owners prefer a lead terminal. This material has good electrical conductivity, it is softer than other metals, which is very good for crimping, in addition, it is resistant to electrolyte, does not create a galvanic couple with it, and therefore does not corrode. In addition, lead is cheaper than others, but it has low temperature melting, which can lead to backfire especially in hot weather.
brass
There is also a brass terminal. It is much heavier, but also stronger than others. It is easily deformed with pliers, which plays in its favor, because for effective work it should fit very tightly to the current terminal. Also quickly removed, has good electrical conductivity and high temperature melting up to 950 degrees.

Copper
Copper terminals for the battery at first glance - the most the best choice. The best possible electrical conductivity, does not oxidize as much, has a larger contact patch. Melts at temperatures above 1050 degrees.
Which terminals to choose
Given all the above information, it will not be difficult to find out which battery terminals are better. Much depends on the conditions in which the product will stay (, type of battery, constant pressure passing through the terminals, or otherwise), as well as from the material from which it is made. Car owners agree that lead terminals are the most versatile - they are quite heavy, soft enough, do not react chemically with acid, and are much cheaper than products made from other metals. At the same time, lead has a low melting point, sufficient, but not the highest conductivity of electricity.
ON this moment there is an unspoken division of batteries into "Europe" and "Asia". If earlier only the European part was engaged in production, now Asian manufacturers are very firmly entrenched in the market and this is not only Japan, but also China, the leader in industrial production. Russian manufacturers, often produce two types at once - both "European" and "Asian". So what are the differences between these batteries, how to identify them ...
Actually, there are not very many differences in these two standards, but they are. The Asian standard is now also quite popular among motorists, because there are a lot of Japanese, Korean (namely from Korea) and Chinese machines in our market. But these batteries are slightly different from the usual European standards. However, there are not so many differences, and in principle, "Asia" can be made to work on a machine with the "Europe" standard, as well as vice versa. There are only three differences, let's take a closer look.
Dimensions
Oddly enough, Asian batteries are often smaller and taller or lower than their European counterparts. Not much plastic is used in their cases, especially there may be no plastic stiffeners. That is, almost always a regular box. It is difficult to put such a battery into the European standard, because it will simply dangle in the mount, and the upper bar (which holds the battery) will simply not effectively fasten to the body, which is also not desirable.
Opposite the “European” battery, you may not put the “Asian” standard into the mount, it will simply turn out to be larger, ALTHOUGH SOMETIMES THE SIZES CAN MATCH!
I myself am still wondering - how Asians manage to shove such Ampere * hours into such compact cases.
Terminals
Here lies perhaps the biggest difference that cannot be passed by. It was by the terminals that Europe and Asia were originally determined. The thing is that the differences here are global:
- - here we have two round terminals, their dimensions are as follows - positive - 19.5 mm, negative - 17.9 mm.
- Asia battery – and there are a lot of differences here. Even the batteries themselves can vary, for flat terminals and for round ones. flat - often they have a thread in themselves, where the terminal is actually screwed, although in fairness, it is worth noting that there are also without threaded connection. Round ones are similar to Europe, that is, oval terminals are put on them, but their sizes are smaller, plus - 12.7 mm, minus - 11.1 mm.
Of course, "Asia" with narrow round terminals can be put on a regular car, but you will have to use special adapters, or tighten the terminals tightly, which can lead to their breakage.
Frame
Another difference is the difference in case type. In Asian batteries, the terminals seem to stick out from above, that is, they rise above it.
In the European version, on the contrary, they are recessed and are, as it were, in niches.
If there is enough space under the hood of the car, then this is not a problem, but if the protruding contacts can reach the hood cover, then this is corny dangerous, and it’s not far from a fire.
These are all the differences between batteries, some may argue that there is more. Guys, this is not entirely true, and Europe and Asia can have different polarities, it all depends on the location of the engine for a particular model. Characteristics of current, voltage, durability can be exactly the same.
This concludes, sincerely your AUTOBLOGGER.
The main thing in the selection of a battery is that it should physically "sit" in its designated place on your car, be connected to the mains and securely fastened.
The next step is to select the electrical characteristics of the battery, capacity and starting current, at this stage, for a more confident start of the engine, we are guided by the principle "the more the better".
Your personal preferences in choosing the battery brand, manufacturer and country of production are also important.
- You can choose a battery yourself, but for maximum confidence, we advise you to contact professional consultants of the Automotive network:
- they will select the battery you need and answer all your questions;
- often the space reserved for the battery allows you to install the battery large dimensions(which means more high performance), which can always be determined by a professional. Upgrading to a larger size not only allows you to install a more powerful battery and increase confidence in starting the engine, but often saves on purchase.
- if necessary, they will carry out express diagnostics of the electrical equipment of your car;
- during the entire service life they will service and charge the battery free of charge;
- Ultimately, they will save you time, nerves and money.
1. Dimensions and standard size
At self-selection The battery should be measured first. dimensions - length, width and height (cases and together with terminals). These parameters define the so-called battery size. Manufacturers produce batteries according to specified and agreed sizes, these are battery sizes. Batteries of the same size are interchangeable. In this case, we are not talking about observing the given dimensions with an accuracy of a millimeter, actual dimensions batteries may differ from the specified standards by +/- 7-9 mm., Such tolerances are usually not a hindrance to replacing the battery. For cars in the bulk, there are three types of batteries: Asian JIS (“horned” batteries), European DIN / EN (terminals flush with the cover) and much less American SAE. In our catalog, we also present the classification of truck batteries - TRUCK.
The JIS standard for passenger cars specifies the following basic sizes: B19, B24, D23, D26, D31, D33, E41. They are deciphered quite simply, the first letter indicates the width of the battery: B - 127 mm, D and E -172 mm, the numbers are the length rounded to centimeters, i.e., for example, the most common size B24 sets the battery length to about 24 cm. ( usually 233-235 mm.). Height of all Asian batteries for cars- about 200 when measured without taking into account the height of the terminals and 220 mm with them. The European standard for passenger batteries includes the following sizes: L1 and LB1, L2 and LB2, ... , L6 and LB6. The letters show the height of the battery, "regular" L -190 and "low" LB - 175 mm. The width of all passenger batteries of the DIN / EN standard is the same, 175 mm. The number after the letters indicates the length of the battery, rounded from 20 to 41 cm. The American BCI standard is little represented in our market and for the most part corresponds to the Asian JIS sizes. An exotic exception is the presence of side terminals, i.e. pole leads on the side face. In our catalog, we include American-standard batteries in terms of dimensions in the JIS classification, indicating the features of the presence of side terminals. We designate cargo batteries in our catalog as TRUCK 19/22/27, where the numbers are the rounded width of the batteries in centimeters, the length of these cargo batteries is 510-520 mm. A separate place is occupied by the size 31T / S - the so-called "stud", batteries with threaded terminals, which are placed mainly on american tractors.
2. Battery polarity
Next important parameter- battery polarity, i.e. location of positive and negative terminals. To determine the polarity, you need to turn the battery towards you with the terminals and determine which side the negative terminal is on (the markings “+” and “-” are usually placed on the battery case near the terminals).
For passenger batteries, "minus" on the left is reverse polarity, left, L (Left) according to the JIS standard, "0" - according to the European standard.
"Minus" on the right - polarity is straight, right, R (Right) - JIS, "1" - DIN / EN. For cargo batteries, the following designations are accepted, "minus" on the left - Russian polarity (gr), L according to the JIS standard, "4" - according to the European standard. On the right - European (euro), R (JIS) and "3" (DIN / EN).
On older vehicles, the length of wires with terminal mounts often allows you to "reach" the battery terminals with either polarity, but in modern machines this is extremely rare.
3. Terminal type
A slightly less important parameter is the type of terminals. Most passenger batteries are produced with standard terminals, positive 19.5 mm, negative 17.9 mm. But on Asian sizes B19 and B24, the so-called "narrow terminals" of 12.7 and 11.1 mm are used. The issue of matching the terminals to the mounts on the car can be solved by using adapters both from standard to narrow, and vice versa. Therefore, for our network, in which such adapters are always available, this moment of selecting a battery is a little less important.
It is quite rare to use batteries with side terminals, when the connectors are under bolted connection located on the side of the battery. Typically, these batteries are installed on american cars.
For trucks domestic cars fastening “for a bolt” is characteristic, for imported ones - standard terminals (under a cone). For this sector, manufacturers are increasingly offering conical batteries with bolt-on adapters. For only conical cargo batteries in our stores there are always such adapters separately.
Cargo size 31T/S is distinguished by threaded terminals - “studs”.
4. Attachment type
The top mount is typical for Asian batteries, it involves fixing a strap on top of the battery, which is then bolted to the car body.
The lower mount is common in European cars. In this case, the battery is attached to the lower ledge, the so-called "skirt", "tide", "shoulder".
Recently, Korean car manufacturers often adopt Asian-style bottom battery mounts. Those. it turns out a mixed situation when the presence of a lower protrusion is required for Asian "horned" batteries. In our portfolio, AlphaLINE brand batteries meet these requirements.
5. Battery capacity
Very often selection starter batteries is carried out according to this parameter. This is the wrong approach, we will explain why.Firstly, the capacity does not determine the physical characteristics of the battery, batteries of completely different sizes (dimensions) can be of the same capacity. Having picked up a battery that is suitable for its capacity, you are not immune from the fact that it does not fit into the space allotted to it.
Secondly, there is an erroneous opinion that if a car has a battery of a certain capacity, then a battery of exactly this capacity should be installed. As an argument, the argument is given that “the generator will not be able to charge the battery larger capacity". The statement is absolutely not true and, moreover, we always recommend installing a battery with a larger capacity. Even looking at the "manual" of almost any car, you can see that a fairly wide range of capacities is recommended.
Whether a battery of any capacity will be charged depends on the balance of charging and power consumption. If your vehicle's power consumption exceeds the capacity of the systems to charge, then a battery of any capacity will not be charged. But at the same time, a battery of a smaller capacity will be discharged faster! Conversely, even with problems with battery power, with a larger capacity, you will be able to drive longer and further. It is a proven fact that at -30 C, the battery capacity decreases up to 2 times. In the conditions of Siberia, in the presence of additional energy consumers (alarm, preheaters, powerful audio systems, heated seats, etc.) after determining the standard size and other parameters described above, for more confident operation of your car, we recommend installing a battery maximum capacity.
6. Starting current
Cold cranking current is the most important parameter for starting your car, especially in cold winters. Simply put, this is the power of your battery, this indicator determines how powerfully the battery can crank the starter and start the car. As well as the capacitance at -30 C, the starting current is almost halved.
The values of current measurements differ according to different standards. The European EN is roughly similar to the domestic GOST. American SAE - Asian JIS. Between themselves, they correlate approximately as I (SAE) \u003d 1.067 * I (EN).
For a confident start of your car engine, we strongly recommend choosing a battery with a maximum starting current within your budget.
7. Trademark, manufacturer, country, city of production
Important factors for many consumers are brand, manufacturer and country of origin. Indeed, even until recently, this was one of the determining factors when choosing a battery. But times are changing domestic producers behind last years greatly increased in manufacturability and quality of products. And in the new economic conditions, the prices for batteries of traditional giants make us more critically evaluate their real consumer qualities.
Over the years, we have studied almost all major manufacturers both foreign and domestic ones. In every price segment from economy to premium, we form the best offer in terms of price / quality ratio. In the current realities, we recommend paying attention to the products of Russian and Korean manufacturers.
In particular, we advise you to consider the battery trademarks X-treme NORD (Alkor, Tyumen) and AlphaLINE (Atlas, South Korea). Both ranges feature state-of-the-art Punch Frame grating technology and calcium-silver alloys. Battery performance is superior to established brands at a lower price.
8. Battery maintenance
By battery serviceability, we mean the ability to access battery banks, the presence of so-called plugs in one form or another. On modern cars the battery charge voltage range is set to 13.8-14.5 A. If this mode is followed, most batteries require virtually no maintenance, and therefore many manufacturers completely remove access to battery banks.
But there are a number of cars on which the operating ranges of the on-board network are set above 14.5 V: GAZ cars up to 2002, some american models release before 2000, etc.
For such cars, according to the instructions, the use of serviced batteries and a monthly check of the electrolyte level in the banks are prescribed. Batteries in such vehicles lose water as a result of the hydrolysis reaction, which leads to a decrease in the electrolyte level, and ultimately to a rapid failure of the battery. If you have access to the instruction manual for your car, check the declared range of the on-board network. Better yet, have a specialist diagnose the operation of the electrical network. You can also get this service at any Automotive store, for customers - absolutely free.
For serviceable VAZ vehicles, the operating range of the electrical network is 13.5-14.5 V, therefore, it is possible to install maintenance-free batteries.
9. AGM technology
In traditional batteries, the electrolyte is in a liquid state, if you shake such a battery, you will hear a splash.
AGM Technology(Absorbent Glass Mat) implies that between the plates of the battery is special material fiberglass, which is then impregnated with electrolyte. Those. the electrolyte is bound.
This design provides complete impermeability of the battery, it can be installed at least “upside down”. The dense arrangement of the components of the AGM batteries provides them with the highest resistance to vibrations, the active mass does not crumble, the battery life is up to 2 times longer than traditional ones.
The starting currents of AGM batteries, as a rule, are significantly higher than those of classic ones. They are stable in deep discharges and withstand a significantly greater number of charge-discharge cycles.
In almost all respects AGM batteries significantly superior to liquid acid, but also higher in cost.
During operation, it is important to monitor compliance with the upper value of the battery charge, AGM batteries are sensitive to overcharging. When the charge voltage exceeds 15.0-15.2 V, active boiling of the electrolyte begins, and due to the tightness of the design of these batteries, restoration of the electrolyte volume is impossible.
10. Punch Frame Technology
Punch Frame - the most advanced technology production of grids (down conductors) of batteries by stamping. The world leader in the production of batteries Johnson Controls (ТМ Varta, Bosch) was the first to widely use this technology.
Stamped grids allow you to increase the electrical characteristics of batteries by 20-30%, the service life - up to 2 times.
In the post-Soviet space, the only manufacturer producing down conductors using the Punc Frame method is the Alcor plant, Tyumen (see X-treme NORD and Buran batteries in our catalog).
This technology is also implemented in AlphaLINE and CENE batteries from South Korean manufacturers.
