How to determine the type of car battery

Types of car batteries

Different types of car batteries include elements that allow for higher voltages. Batteries differ in connection method; for some devices it is serial, for others it is parallel. Electrode materials have liquid or gel electrolyte.

What is a battery and why is it needed in a car?

A car battery, like a generator, serves as a source of electricity and performs the following functions:

supplies current to the starter when the engine starts;
supplies power to the switched-on consumer when the generator is operating;
participates in transient processes that require high voltage;
helps smooth out the pulsating current.

Lead-acid batteries in passenger cars differ in type. Over time, devices are improved. One battery includes 6 separate batteries connected in series. The body of such elements is made of polypropylene, it is resistant to acids.

One of these mini-batteries includes several positive and negative electrodes. The purpose of the separator is to insulate electrodes of opposite polarity. Each individual electron is made of lead or a lead-calcium alloy.

This type of battery has a low charge level. Hybrid batteries have a simpler design. To ensure that the electrodes have increased resistance to corrosion, a small amount of tin is added to the lead. The structure of the electrodes resembles a lattice. Each is in an electrolyte - a sulfuric acid solution (or gel).

Main types of car batteries - brief description, marking

Different types of car batteries have different power, cost and performance characteristics. Researchers are trying to increase the energy consumption of devices. Frost-resistant batteries are being developed. Existing batteries contain hazardous substances: lead and sulfuric acid. The developers plan to create more environmentally friendly units.

Antimony

The lead plate of such batteries contains from 4.8 to 5% antimony, which makes the lead denser and enhances electrolysis. When gases are released, the water seems to boil. As a result of such processes, the concentration of electrolytes increases.

To compensate for the loss of moisture, purified water is poured into the battery. Batteries containing less antimony are popular. The devices are easy to maintain. Modern car batteries contain virtually no antimony.

Low antimony batteries

The plates of such batteries have a minimal amount of antimony (less than 4.8%). Devices may not be monitored. In this case, some water boils away. A low-antimony battery does not place high demands on electrical equipment. It is available in Russian passenger cars. The main advantage of the device is its affordability.

This type of battery contains alkali. They are divided into 2 types: nickel-cadmium and metal hydride.

The positive plates are made using nickel hydroxide, the negative plates contain a small amount of cadmium and iron.

Nickel-cadmium alkaline batteries are easy to use. The peculiarity is that during chemical reactions the electrolyte remains and does not boil away.

Alkaline batteries have many advantages over “classic” ones:

They can handle overcharging normally. You can store them unloaded.
Alkaline batteries are convenient to use if the temperature is low. In winter, the engine will start quickly.
Acid batteries emit harmful substances, while alkaline batteries do not.

The main disadvantage is the high cost. The devices weigh a lot and are often used in trucks.

Calcium

To make less water boil away, calcium was used instead of antimony. Calcium batteries are marked “Ca/Ca”. It indicates that the device parts contain calcium. And if a small amount of silver is added, the battery resistance decreases, resulting in an increase in energy capacity.

When calcium began to be used, gas emission decreased and water consumption decreased. Low antimony batteries are inferior to ring batteries. A battery that contains calcium is often called “maintenance free.” This device has a long service life and water boils away slowly.

Car batteries whose plates contain calcium are stored for a long time and do not lose their performance properties.

But calcium batteries have several weaknesses:

places high demands on recharging;
is sensitive to on-board network voltage;
reacts poorly to temperature changes.

A calcium battery is more expensive than a low-antimony battery, but the price justifies the quality. Batteries of this type are installed in foreign cars. The disadvantage of a calcium battery is that it requires excessive recharging. But with proper care, it becomes a reliable, long-lasting power source.

AGM and gel batteries

The above types of batteries contain a sulfuric acid solution, and AGM contains a gel. The devices are installed in expensive foreign cars; they are more reliable and safer than “classic” ones.

Sulfuric acid diluted with water flows out immediately if the housing is damaged. The gel-like electrolyte has an increased density; it is not as fluid as a liquid. There is a material between the plates that holds the gel inside. The function of this material is to protect the electrodes.

The designation “AGM” (Absorbent Glass Mat) translates as “material with absorbent properties.” The gel is fixed in the aggregate. Such a battery can be tilted without fear that the liquid will leak out if damaged.

One of the advantages of the battery is its excellent vibration resistance. It has a low charge level, so it can be stored for a long time. It is recommended to keep the gel battery charged. Another plus is its resistance to overcharging.

Do not subject the battery to rapid charging. Less current should be used. Gel batteries have a special charging device. In addition to their advantages, such batteries have weaknesses. They do not work well if the air temperature drops sharply. If the battery is stored in favorable conditions, the service life will be up to 11 years. Another drawback of the battery is its high price.

Hybrid batteries

These batteries are marked “Ca+”. The device plates have electrodes that differ in production technology. Positive ones are low in antimony, and negative ones are calcium. Hybrid batteries consume little water, this is their advantage. The devices are reliable and resistant to overcharging.

Lithium-ion batteries

In terms of quality, they are compared to gel ones. The chemical elements of such batteries have lithium ions. Negative electrodes contain graphite, positive electrodes contain lithium phosphate material, which is non-toxic. It is environmentally friendly, safe and easy to recycle.

Lithium-ion batteries produce relatively high voltage and have a low self-charging level. They are used infrequently because they are sensitive to temperature changes.

Lead batteries are being replaced by other types. AGM battery devices are becoming increasingly popular, but their cost is higher than other types. In the future, it is planned to create batteries that will not contain liquid.

Vital: how to choose a battery for a car and not make a mistake

What about the old one?

the product is simply discharged (charged battery voltage is 12.6-12.7 V) and should be charged with a special device;
the density of the electrolyte has decreased: it must be measured with a hydrometer - it should be at least 1.25-1.27 g/cm3;
sulfation of the plates has occurred (the plates are covered with a large layer of lead sulfate and stop passing current) - can be cured using a special charger with a desulfation mode;
The electrolyte level in the jar has dropped - you need to add distilled water.

You should also check whether the car's alternator is working properly. To do this, it is necessary to measure the voltage at the battery terminals with the engine running - it should be in the range of 13.8-14.5 V. It would not be superfluous to check whether there are current leaks to any sources when the car is parked, whether the starter is working and not oxidized power wiring terminals.

We classify car batteries and find out which one is better to choose in certain conditions

Traditional lead-acid batteries with liquid electrolyte.
EFB (Enhanced Flooded Battery).
AGM (Absorbed Glass Material).

Traditional wet batteries consist of six cells containing lead plates and liquid electrolyte. To prevent lead from falling off the plates, they are further strengthened. Depending on the reinforcing material, energy sources of this class are usually divided into several subtypes:

low antimony (lead-antimony electrodes);
calcium (lead-calcium electrodes);
hybrid (electrodes “+” – lead-antimony, “-” – lead-calcium).

Low antimony current sources

When deciding how to choose a battery for a car, you should keep in mind that low-antimony batteries are marked Sb on the label. These products have excellent resistance to deep discharges. The models belong to the serviceable class because they have removable lids for access to the electrolyte jars. At the same time, low-antimony specimens require frequent maintenance and have the following disadvantages:

intense evaporation of electrolyte;
low resistance to self-discharge;
low starting current;
small capacity.

Calcium Energy Sources

Calcium batteries are classified as maintenance-free, since their design does not provide access to containers with electrolyte. The lids of such models, on the contrary, have special labyrinth channels for collecting electrolyte condensate. This is by no means a disadvantage of the product, since batteries of this type are prone to minimal evaporation of the conductive liquid. The positive characteristics of calcium batteries include:

large capacity;
high starting currents;
adding silver to the electrode structure;
low self-discharge during storage.

Products of this class are not without their disadvantages. In particular, they do not tolerate deep discharges. And 3-4 discharges lead to a loss of battery capacity by 80%. KIA Rio car owners will not be pleased with the price of Ca/Ca batteries.

Hybrid batteries

Products that are labeled with a phrase like “Hybrid battery” or an inscription in the form of Sb/Ca belong to the class of hybrids, which have average electrical characteristics. The batteries are low maintenance and resistant to deep discharges. When choosing traditional batteries for a car and figuring out which one is best to choose, experts recommend giving preference to hybrid sources.

AGM batteries

In Absorbed Glass Material products, the electrolyte is held in a microporous glass fiber material sandwiched between the plates.
The free volume of micropores serves for the process of closed gas recombination, due to which hydrogen and oxygen are retained inside the structure. On such models you can often see the Start-Stop inscription. And for good reason, because the AGM battery family is often found on Jaguar F-Pace with a start-stop system and regenerative braking. In the set of advantages:

high starting current;
resistance to deep cyclic discharges;
durability;
ability to work in any position.

EFB batteries

Enhanced Flooded Battery – models with wet electrode technology.
The electrodes here are covered with a film of special microfiber. This prevents the possibility of material shedding from the plates, which, as in the case of AGM, allows it to withstand deep cyclic discharges. Unlike Absorbed Glass Material, the electrolyte here is liquid. It should be noted that AGM and EFB batteries will in the near future replace traditional products with liquid “electrolyte”. For now, the limiting factor is the too high price of progressive class models: they are 2-2.5 times higher than the cost of “traditional” ones.

Who to give preference to: how to choose a modern battery for a car on your own

The automaker has allocated a special place for the battery - be it in the engine compartment or in the trunk. The dimensions of the niche are strictly fixed, which means you can’t make a mistake with the dimensions of the “box”. For most European cars, the required overall dimensions are 242x175x190 mm.

Terminal Configuration

On most European cars, the terminals are standardized and easily fit into designated recesses on the battery. This cannot be said about other cars, for example Asian ones. The terminals of the latter often do not fit into the molded square of the “European box”, but the Asian standard size comes in handy.

Polarity

Before choosing a battery for your car, you must make sure the location of the negative and positive poles. If this is not done, the wires may not be long enough to connect the terminals to a power source with a different polarity.

Country of origin

Russian and European methods for monitoring the performance of electric batteries differ significantly. European requirements are much stricter, which means the quality of the guaranteed characteristics is obviously a little better.

date of manufacture

You should buy the “box” that has been on the store shelf for no more than 6 months.

Nominal capacity

Starting current

The rated starting current can also be found on the old battery. The higher this indicator, the easier it is for the product to light the starter.

In terms of warranty service, preference should be given to those devices with a warranty period of at least two years.
During the selection process, do not forget about the following tips:

if an AGM was installed, then it must be replaced with a battery with adsorbed electrolyte;
Having chosen a certain model, you should ask the seller to check it with a load plug: the voltage does not fall below 9 V and begins to increase over time - you can safely take such a product;
Once you purchase the product, be sure to fully charge it.

Brands: which company to choose a modern car battery from a variety of manufacturers

The domestic motorist has the opportunity to choose products from a large number of models from the CIS countries, Europe and Asia. A huge number of models, a huge gap in price ratio - even an experienced car enthusiast can get confused here.

When analyzing the topic of which company to choose a battery for a car, it would be appropriate to refer to the battery rating . Here experts recommend not to give preference to newcomers and outsiders. In general, the situation with brands looks like this:

The market favorite is considered to be models of German origin - Bosch. They are reliable at any temperature, high quality and durable;
a high-quality analogue to Bosch models are products from the Varta concern. These products have been awarded more than once for best value for money;
The batteries of the Tyumen Battery Plant can give foreign leaders a head start. Tyumen Battery have excellent electrical characteristics, are serviceable and have a very reasonable price tag;
Batteries from the companies Zver, Topla, Exide, Medalist, AKOM, Mutlu are considered to be strong middling ones.

AGM and EFB technologies are within the capabilities of market favorites – Bosch and Varta. Banner and Exide make good AGMs.

Marking and classification of car batteries

A car battery is a backup power source that no car can do without. The principle of its operation is quite simple. While driving, part of the energy generated by the engine is stored in batteries. As soon as the engine is turned off, the on-board network begins to operate from the battery.

Like any other part, the battery deteriorates over time. This usually manifests itself in the fact that its capacity decreases. If you use the battery extremely carelessly, it can be completely discharged.

Of course, there are special techniques that allow you to charge the battery, but you must keep in mind that some batteries simply cannot be restored. In this situation, you will need to purchase a new device, and for this you need to know which device with which marking is suitable for you.

Battery classification

There are a huge number of different batteries on the market. Automobile companies go to all sorts of tricks to achieve greater efficiency, increase the volume and life of their devices. Therefore, before moving on to a more detailed classification, we will divide all devices into serviceable and unserviceable.

Maintenance-free batteries include those that exclude the possibility of pouring water inside. One of the advantages of such devices is that almost all of them have an indicator that is responsible for the battery status.

Serviced batteries require constant care. The driver must periodically pour distilled water inside. It will compensate for the electrolyte that has evaporated during operation.

A more detailed classification of batteries consists of division by plate type:

lead-antimony,
lead-calcium,
hybrid.

Each type has its own advantages and disadvantages.

General labeling requirements

Car batteries are produced by many engineering companies; it is not surprising that this market segment cannot be avoided without common labeling.

However, different car companies put different labels on their batteries. Moreover, the batteries themselves differ in a number of parameters and classes.

In addition, each country has its own requirements for battery labeling. Taking into account the fact that in the modern globalized world, cars are assembled through the cooperation of companies from different countries and continents, there are a number of international standards that manufacturers are guided by.

According to current international standards, battery labeling must include the following data:

manufacturer's mark,
Company name,
rated voltage value,
capacity value,
polarity near the terminals,
Battery Type,
production date,
number of cans.

Also, the battery labeling should include signs limiting operation and warning about transportation standards. In general, four types of marking can be distinguished depending on the region:

Types of marking depending on region

In Russia, battery labeling is regulated by GOST 959-91. It is also called “A B C D”. These letters represent the following concepts:

“A” - this letter in the marking indicates how many cans are in the battery. One element - two volts
"B" - battery type. The “ST” marking indicates that this is a starter-type battery.
“C” is the capacity of the device. The unit of measurement is ampere hours.
“D” - indicates the material from which the unit is made.

These are the main parameters that largely determine whether a given battery is suitable for you. Variations of execution are described in detail in the figure above.

European marking

It is worth recognizing that in Europe the requirements for batteries, especially their environmental friendliness, are much higher. It is not surprising that European labeling also has significant differences.

In Europe, car battery manufacturers focus primarily on the DIN standard when creating their products. It includes the use of five basic numbers in markings.

Five-digit marking is determined by the following parameters:

The first three digits indicate the battery capacity. To accurately determine this parameter, you need to subtract 500 from the written number.
The two numbers at the end indicate the battery type.

One important clarification needs to be made here. Despite the simplicity of the official standard, each manufacturer tries to indicate as much useful information as possible on the batteries. Therefore, by studying the labeling of a European battery, you can find out the following data:

execution,
terminal specification,
features of gas removal,
vibration strength indicator.

ETN battery marking consists of the following indicators:

The first number indicates the capacity.
The second and third are the power range. The number six in this marking means that when calculating you need to add 100 Ah, seven - 200 Ah.
The next three numbers are the design solution and the materials used.
At the end there are three numbers indicating the value of one tenth of the cold scroll.

When you study the markings of a European battery, you should understand that it may have many additional markings that the manufacturer applies at its own discretion.

Asian labeling

In the Asian market, JIS standard battery markings are used. It is worth recognizing that it is very confusing, and it will take time to understand it. Of course, you can’t do without special tables.

Asian battery markings consist of six characters:

The first two digits traditionally indicate capacity. But you must take into account that the nominal parameter is multiplied by the correction factor.
The third character is a letter. It indicates the shape of the battery and its size ratio.
The next two characters are the size in centimeters (length).
The last symbol has only two meanings - R b L. It indicates the location of the negative terminal.

The capacity of the Asian battery, which is indicated in the labeling, is significantly lower than the European one.

American numbering system

In America, the SAE standard is used to designate batteries, but other options are possible. In this context, US legislation provides quite a wide scope for the activities of entrepreneurs.

American marking of batteries is carried out in accordance with the SAE standard. However, other types of markings may be used. Traditionally, the number of characters in the nomenclature is six (one letter and five numbers). These symbols have the following meanings:

The first letter indicates the type of battery.
The first two digits determine the size of the device.
The last numbers in the nomenclature are the current value during cold cranking.

Very often, manufacturers mark the reserve capacity indicator on their devices. You can also find on the case how long it takes to reduce the voltage to 10 V. A fixed current indicator of 25 amperes is taken as a constant.

Basically, batteries are classified into serviceable and maintenance-free. They can also be divided into types due to the design features of the plates. Labeling of devices depends on the region in which the product was manufactured and the manufacturer's factory standards.

Decoding the labeling of batteries from different manufacturers

When purchasing a battery, it is very important to know its characteristics, year of manufacture, capacity and other indicators. As a rule, all this information is shown by the battery labeling. Russian, American, European and Asian manufacturers have their own recording standards. In the article we will look at the features of labeling of various types of batteries and its decoding.

Labeling options

The marking code will depend not only on the country of manufacture, but also on the type of battery. Different batteries are used for different purposes. There are starter batteries that are designed for use in cars. There are more powerful ones, dry charged ones and others. All these parameters must be specified for the buyer.

Battery marking

As a rule, the labeling should contain the following information:

name and country of manufacturer;
battery capacity;
rated voltage, cold cranking current;
battery type;
date and year of issue;
number of elements (cans) located in the battery case;
polarity of contacts;
alphabetic symbols that show parameters such as charge or service.

Each standard has its own common features, but also its own characteristics. For example, it is very important to be able to read the manufacturing date. After all, the battery must be stored under special conditions and at a certain temperature. Improper storage can affect the quality of the battery. Therefore, it is better to choose fresh batteries that are fully charged.

Russian-made batteries

Marking of Russian-made batteries is carried out in accordance with GOST 959-91. The meaning is conventionally divided into four categories that convey specific information.

The number of cells (cans) in the battery case is indicated. The standard number is six. Each produces a voltage of just over 2V, for a total of 12V.
The second letter indicates the battery type. For automobiles, these are the letters “ST”, which means “starter”.
The following numbers show the battery capacity in amp hours.
Further, the letters may indicate the case material and the condition of the battery.

Marking of Russian-made batteries

Example. 6ST-75AZ. The number "6" indicates the number of cans. "ST" indicates that the battery is a starter battery. Battery capacity – 75 Ah. “A” means that the case has a common cover for all elements. “Z” means the battery is filled with electrolyte and charged.

The last letters can mean the following:

A – general battery cover.
B – the battery is filled with electrolyte and fully charged.
T – the body is made of thermoplastic.
M – the body is made of mineral plastic.
E – ebonite body.
P – separators made of polyethylene or microfiber.

The inrush current value is not indicated on the label, but can be found on other labels on the housing. Each type of battery of different power has its own starting current strength, housing dimensions and discharge duration. The values are shown in the following table:

Rechargeable batteries: types and applications, which one is better to choose for a car

For autonomous power supply, chemical current sources (CHS) – galvanic elements (cells) – are most often used. The principle of their operation is that the energy of the redox reaction is converted into electrical energy.

One cell produces voltage up to 4 V, so to obtain a powerful source, several cells are connected into a battery. After the complete consumption of the supply of reagents, the HIT is discharged and loses its functionality. This problem is solved by rechargeable batteries (accumulators, accumulators) - rechargeable, reusable devices.

What is a battery and what is it for?

Batteries differ from simple batteries in the reversibility of the chemical process. After discharge, they are connected to the electrical network. The current passing through the battery restores the charge.

This type of HIT is used in everyday life and in production to store electricity and provide it to cars, portable tools, mobile devices, as well as in uninterruptible power supplies (UPS) for stationary devices.

Various types of rechargeable batteries are included in autonomous power supply systems, including those powered by alternative sources (solar, wind power plants). That is, they are needed in all cases where a current reserve independent of the centralized power supply is required.

Main types of rechargeable batteries and their areas of application

The basic characteristics of all batteries depend on the material the electrodes are made of, as well as on the physical state and chemical composition of the electrolyte.

Types of batteries.

Car batteries have one more parameter - polarity:

Straight. The positive terminal is on the left, the negative terminal is on the right. This type of battery is most often found on Russian cars.
Reverse. The positive terminal is on the right, the negative terminal is on the left. This is an option for most European cars. It is impossible to replace a battery with direct polarity with a battery with reverse polarity.

Classification of currently existing batteries according to the chemical composition of the electrolyte:

lead-acid;
alkaline;
lithium (lithium ion);
nickel-salt.

Lead acid batteries

Lead-acid batteries are most often used in cars and UPSs.

They consist of several small cells (cans) located in a single housing. Inside each there are lead plates and electrolyte. 1 cell gives a voltage of 2.1 V. To start the engine, a current of 12.6 V is needed. Therefore, 6 battery cans are combined in the battery.

Types of lead-acid batteries used in cars and UPSs, according to the chemical composition of the electrodes:

antimony and low antimony;
hybrid;
calcium and silver-calcium.

Classification of lead-acid batteries for cars and UPSs according to the state of the electrolyte:

with liquid electrolyte - first generation, now almost never used;
gel – second generation;
AGM - third generation.

Antimony

These are lead-acid batteries with an antimony content of more than 5%. During their operation, it is necessary to periodically add water, which is why they are called serviceable. Another drawback is their high self-discharge. Antimony batteries are not currently used in cars; they are used only as stationary power sources where there are no high requirements, but low cost is important.

Low antimony

They differ from antimony ones by their reduced antimony content (up to 3%). Battery maintenance is easier, self-discharge is less. The advantages of low-antimony batteries are low price and resistance to deep discharge. The scope of application of batteries of this type is Russian passenger cars.

Calcium

Lead-acid batteries, in which calcium is added instead of antimony, differ from low-antimony batteries in two respects:

water consumption is 80% less;
Self-discharge is 30% lower.

The main disadvantage of calcium batteries is that when discharged to a level below 70%, an irreversible loss of capacity occurs.

It is impossible to restore it with direct current. Manufacturers of car batteries solved this problem by producing silver-calcium batteries. They are not afraid of deep discharge and are more resistant to corrosion. Disadvantages of batteries with silver: high price, inability to control the electrolyte level.

This type of battery is an attempt to combine the advantages of calcium and low-antimony batteries. The result is a battery with reduced water consumption and increased resistance to deep discharge and voltage surges.

AGM and gel batteries

In 1st generation batteries, the electrolyte is a solution of sulfuric acid in distilled water. The disadvantages of liquid electrolyte are that it is harmful to human health and there is a risk of leakage and damage to nearby objects.

In a 2nd generation battery, the electrolyte is in the form of a jelly (gel). A solution of sulfuric acid is mixed with a thickener - silicon dioxide. Such batteries are called gel batteries, or made using GEL technology. They can work in any position, leakage is excluded. Areas of application, in addition to automobiles and UPSs, are aviation, military equipment.

Additional advantages of gel batteries:

low self-discharge;
resistance to high temperatures;
complete recovery from deep discharge.

The disadvantage of batteries manufactured using GEL technology is the need for a special charger.

3rd generation batteries contain porous glass fiber impregnated with electrolyte - Absorbent Glass Mat (AGM). They have all the advantages of gel batteries and are resistant to low temperatures. In the cold, gel loses electrical conductivity; fiberglass does not have this disadvantage.

The electrolyte instead of acid in this type of battery is an aqueous solution of potassium or sodium hydroxide. Alkaline batteries differ in the chemical composition of the electrodes.

The areas of use of alkaline batteries are indicated in the table.

Alkaline batteries are not installed on passenger cars, and rarely on trucks.

Advantages of alkaline batteries compared to acid ones:

less weight;
possibility of storage in a discharged state;
higher strength;
short circuit resistance;
no release of harmful substances;
resistance to low temperatures.

The disadvantage of alkaline batteries is their relatively low efficiency.

Lithium-ion

This is the most common type of battery for mobile phones, laptops, tablets and e-readers, video and photo cameras, radio stations, but is also used in cars.

The electrolyte in them is lithium salts in the form of a solution or in a solid state. Electrodes can be made of graphite, aluminum, copper.

Advantages of lithium batteries:

high energy density;
no maintenance required, ready for use at any time;
low self-discharge;
housing tightness;
light weight;
long service life, a large number of discharge-charge cycles;
the ability to create batteries of different shapes;
wide range of operating temperatures – from -20 to +50°C.

The disadvantage of lithium-ion batteries is that when deeply discharged they can lose capacity and fail. In case of prolonged inactivity, periodic charging is required.

Types of lithium batteries: lithium-manganese, lithium-iron-phosphate, lithium-chlorine, etc. An improved version is lithium-polymer batteries.

Nickel salt

The electrodes in these batteries are made of nickel and sodium, the electrolyte is a ceramic separator glass and molten table salt.

complete tightness;
absence of harmful components and release of hazardous gases;
light weight;
long service life;
suitability for operation at extremely low and high temperatures;
Possibility of storage for up to 20 years without deterioration of characteristics.

Areas of application: telecommunications, alternative energy supply, railway transport, oil and gas industry, high-power energy storage systems, etc.

How to Determine Your Best Battery Type

Devices and equipment that require autonomous power supply are most often sold together with a battery. If it fails or is lost, you will need a spare battery, and it is better to buy a battery of the same manufacturer and type as the original one. If this is not possible, then select a battery of the same shape with exactly the same or superior characteristics. To make the right choice, it’s easier to take with you to the store an old battery or documents from a device or machine that requires a new power source.

If a battery is required for an autonomous power supply system, then the choice is made based on the conditions in which the battery will operate: air temperature, probability of deep discharge, required capacity, etc.
