The battery should be selected taking into account several parameters.

There are a lot of models on the market and the most important thing is that the battery capacity matches that required for your car. It is measured in ampere hours, information about which is contained not only in the accompanying documentation, but also on the device itself. You should not overpay for additional features; some of them may not be useful to you or may not be suitable at all.

The dimensions of the battery must correspond to the size of the space intended for it under the hood or in the trunk (if it is a spare battery, for example). If this is not taken into account, then it may not fit, or lead to more unpleasant consequences when the wires touch other metal parts, for example, the hood, and this will lead to a short circuit or fire.

Selecting a battery according to the make of the car is also important because it takes into account other characteristics of the device, for example, polarity. Your car may have “direct” polarity, when the “minus” terminal is on the left, or “reverse” polarity, when the “positive” terminal is on the right. We will offer a model that matches your car.

The cost of a battery depends on the size, capacity and ability to service it. The most reliable and safe are maintenance-free batteries. Their performance characteristics are significantly higher than those of serviced and low-maintenance models. However, their cost is slightly higher than the price of other batteries. Cheap and high-quality batteries include rechargeable batteries.

If you know exactly the dimensions, polarity and other characteristics of the battery that fits your car, you can use our selection by parameters. The result of the selection will be batteries from all popular manufacturers that correspond to each of the selected parameters. This is very convenient when you need to compare prices for similar batteries from different manufacturers.

Being one of the most important parts of your car, choosing a battery for a car is not such a simple procedure. After all, as all car enthusiasts know, most problems with starting in winter are caused by the battery, and in the summer there will be no less problems due to boiling of the electrolyte or complete failure of the car battery. Therefore, the selection and purchase of a car battery should be approached with full responsibility.

Car batteries are distinguished according to the following criteria:

1. electrical (nominal) capacity, Ah;
2. polarity (straight or reverse);
3. starting current (measured in Amperes);
4. Dimensions of the battery case in mm.

One of the main parameters that you should pay attention to when choosing a car battery is the electrical capacity, the amount of electricity that can be stored and, if necessary, transferred to the load of the car battery. It is also worth considering that the remaining energy that remains after starting the engine is high enough, as this guarantees you the ability to restart if the attempt fails. But deep discharge of batteries is not tolerated very well; it significantly reduces their service life. When buying a battery for your car, you should also take into account the power of the engine itself, as well as its type, because for a diesel engine it is worth buying a car battery with some capacity reserve. In our store we offer you batteries of various electrical capacities: 40 a/h, 55 a/h, 60 a/h, 80 a/h, 90 a/h, 100 a/h and others.

Also, do not discount the starting current, which is the most important characteristic responsible specifically for the cranking power. This term starting current usually refers to the maximum current supplied by the battery for several seconds to start the engine. The specified time refers to an interval from 3 to 30 seconds, which varies depending on the battery testing methodology adopted in a particular region. It is easy to determine the starting current; for this purpose there is a special marking applied to the battery cover.

If you purchase a battery with a large reserve of starting current, you should not expect that you will forget about the problems forever. Any battery requires careful and regular care, even if it is considered maintenance-free. In this case, care will consist of periodic recharging after the car has been running for a long time in the urban cycle - with low mileage, speeds and standing in traffic jams. And diagnosing and timely eliminating electrical equipment problems will help extend the life of your battery and avoid many unpleasant moments.

Among other things, it is worth paying attention to such an equally important characteristic as overall dimensions. Despite the fact that the size of the battery is not directly related to its characteristics, it may simply not fit in the place intended for installation. Before purchasing a battery, you should check its overall dimensions. For example, an excessively “high” size will cause a short circuit and fire if the battery terminals touch the metal hood.

You should also take into account the location of the “positive” and “negative” terminals on the top panel of the battery; they come in “straight” and “reverse” polarity.

When choosing a car battery, you should know what the markings on its label mean:

55, 60.80 Ah - the nominal capacity of the battery, this is the amount of electricity that a fully charged battery is capable of delivering when discharged to the minimum permissible value.

12V - nominal voltage

520A, 580A - starting current, indicated on all batteries and is a very important characteristic.

Having learned about the main criteria that you should pay attention to when buying a car battery, but if you still have questions, our specialists will help you make the right choice. On our website you will find car batteries from various manufacturers - BOSCH, VARTA, MOLL, DELKOR, MUTLU, TITAN and many other well-known brands.

To make it easier to choose the right car battery, a convenient calculator has been developed that will help you choose the model you need. If you know your car well enough and have no doubt that you will be able to choose the right battery, then you need to go to the battery selection tab by parameters. You can also make your choice easier and use the selection of batteries by car brand. Here you can find batteries for absolutely all brands of cars - Toyota, Honda, Subaru, Audi, Mercedes, etc.

The battery selection service allows you to select a battery for your car according to the following parameters: capacity, polarity, terminals (standard, non-standard), dimensions (length, height, width), cold load current.

Knowing these parameters, you can easily select the right brand of battery for your car brand.

The database contains about 100 brands and more than 1000 car models. The total number is 23,000 models.

BATTERY SELECTION CRITERIA

The importance of the battery cannot be overestimated. The stability of engine starting and the serviceability of the electrical equipment of the machine depend on its serviceability.

Choosing the wrong power source can lead to a number of operational problems and additional costs in the future. But it’s easy to avoid problems - just understand the battery parameters and use the knowledge in the purchasing process.

Capacity

The stability and operating life of a battery largely depends on capacity - an indicator characterizing the amount of electrical energy supplied by the power source over a certain period of time.

Thus, a capacity of 40 Ah is evidence of the battery’s ability to supply a load with a current of 1 A for forty hours or a current of 2 A, but for 20 hours.

There are two types of container:

• Nominal - a parameter characteristic of a 20-hour discharge. This indicator is written on the label of the power source. For the Russian market, this requirement corresponds to GOST 959-91. To calculate the nominal capacity, the device is discharged for 20 hours with a current of 5% of the nominal capacity parameter. For example, for a 20 A*h battery, the discharge current is 1 A. The discharge process stops when the voltage reaches 10.5 Volts (for a 12-volt power source).
• Reserve - capacity typical for batteries sold on the American market. The reserve capacity reflects how long the battery produces a current of 25 A. Measurements are made at a temperature of 27 degrees Celsius. So, for a power source with a capacity of 55 A*h, this parameter reaches one and a half hours. If the generator fails, the car will be able to move for the mentioned period of time.

Power

An equally important criterion for choosing a battery is the output power provided by the power source. The parameter is measured under two conditions:

1. Ambient temperature - 18 degrees Celsius;
2. The measurement time is half a minute.

Using this parameter, experts judge the battery’s ability to start a cold engine.

The calculation is made using the formula: P=I*U, where U is the discharge voltage parameter, calculated as the arithmetic mean value, and I is the starter discharge current.

If we consider the power parameter for lead batteries, then the speed at which the starter cranks the engine crankshaft depends on it.

It turns out that the greater the power of the power source, the higher the inrush current supplied.

The starter discharge with a certain current (determined by the manufacturer) shows how long the battery can supply the starter to start the power unit.

The optimal power of the battery is determined by the developers of the starting system, taking into account the tests performed.

The final parameter is recorded in the technical passport of the machine. It is for this reason that it is recommended to select a new power source.

Polarity

When purchasing a battery, pay attention to such a criterion as polarity. If you make the wrong choice, the wires may simply not reach the terminals.

There are two types of polarity - forward and reverse. In the first case, the “minus” is on the right side, and the “plus”, respectively, on the left.

Otherwise, we are talking about reverse polarity.

The first type of polarity is typical for batteries produced in the CIS countries, and the second - for the countries of the European continent and the USA.

Terminals

A mistake made by novice car enthusiasts is insufficient attention to the type of terminals, which may differ in thickness and type of fastening.

Thus, in European batteries the thickness of the “plus” is 19.5 mm, and the “minus” is 17.9 mm.

In the Asian version (Japan and Korea) - 12.7 and 11.1, respectively. It turns out that an Asian battery can be installed on any car, but a power source from Europe cannot be installed on an Asian car - you will have to change the terminals.

In addition, some older cars use a “bolt-on” type of fastening.

Remember one more important thing - in batteries up to 110 Ah, the terminals are on the long side.

Dimensions (length, height, width)

An equally important criterion is the overall dimensions. To be on the safe side, measure the height, length and width of the old power supply before purchasing a new device.

It is important that the width corresponds to the factory setting, but the height and length may vary within a small range.

This is due to the fact that in most models the battery is mounted using the lower protrusions on the sides of the device. Do not overdo it with the height, because if the parameter is too high, the hood may not close.

Starting current (cold cranking current)

The magnitude of the starting current depends on many parameters. It happens that batteries of the same capacity and dimensions have different cold cranking currents.

The reason is that this parameter increases with increasing porosity of the lead plates used, increasing their number, or in the case of using orthophosphoric acid in the paste.

Increased starting current is usually typical for cars with diesel engines. Thus, a battery with a capacity of 55 Ah for a gasoline engine has a starting current of 255 A, and a battery for a diesel engine with the same capacity has a starting current of 300 Ah.

If upon purchase you find that the cold cranking current is higher than the recommended parameter (if other indicators are consistent), then this is only a plus. Such a battery will crank the engine better in cold weather. Use this knowledge when...

Do not be afraid that this parameter will negatively affect the condition of the electrical elements of the car. All that the starting current affects is the quality and reliability of starting the power unit.

Regardless of this parameter, the voltage on the battery remains unchanged.

Flooded or dry-charged battery

A big plus for car enthusiasts is that when purchasing a battery, the device is ready for use and does not require additional preparation.

Now there is no need to take the power source to the garage and fill it with electrolyte. Everything you need is already included in the device.

The manufacturer, as a rule, uses only high-quality electrolyte with a minimum content of impurities. But still, when buying a flooded battery, its quality is worth checking.

In addition, problems with choosing a high-quality electrolyte are also possible.

As for a dry-charged battery, the characteristics can only be determined after installation and start of operation.

Such batteries are worth buying if you do not plan to put them into operation immediately.

The main advantage of dry-charged power sources is their long shelf life, which is 3-5 years with a guarantee of maintaining their original qualities. The only exception is the loss of dry charge during the first year of operation after removal from storage.

The disadvantage of a dry-charged battery is that it cannot be used without prior preparation. Before installation on the machine, the device cans are filled with electrolyte, after which it is worth waiting for impregnation for 30-60 minutes.

To avoid problems, additionally pay attention to the following criteria:

• Integrity of the battery case;
• Availability of a label with all parameters (power, capacity, etc.).

Serviced or not serviced

All batteries are divided into two categories:

Serviced batteries.

Devices in which you can physically unscrew the cap from the cans, evaluate the contents and add technical fluid (if necessary).

The following actions are also available to the car owner:

• Visual inspection of lead plates;
• Checking the condition of the electrolyte;
• Density measurement;
• Assess the electrolyte level in each can.

The main advantage of such a battery is the ability to monitor its condition and the availability of repairs (if necessary).

But serviced power supplies have a number of disadvantages:

• Due to the lack of tightness, the technical fluid may boil away or evaporate (especially in hot weather).
• If the level of electrochemical fluid decreases, the car will no longer be able to start.
• On the open part of the plates, the sulfation process quickly occurs.
• The owner has to constantly monitor the electrolyte level (especially in the summer).
• The evaporation of acid leads to the appearance of a white coating on the surface of the battery. This increases the risk of shorting the terminals.
• In summer, water evaporates first, which leads to an increase in acid density. As a result, the plates break down faster.

Thus, a serviced battery is somewhat of a headache for car enthusiasts, because you have to check the electrolyte level at least once every 2-3 weeks, and the shelf life of such devices does not exceed 2-3 years (if used incorrectly, the total is less).

Maintenance-free battery.

Power supply with six plate packs and electrolyte in a sealed plastic casing. This device has no traffic jams.

If an electrochemical liquid boils, it rises in the form of steam, condenses, and then drains. For beginners, such a device is the best option, because there are no problems with maintenance.

On the other hand, there are also disadvantages:

• There is no way to control the state of the electrochemical fluid;
• If the electrolyte level decreases, it is not possible to top it up;
• If any of the cans fails, you will have to throw away the entire battery.

The inability to top up electrolyte and maintain the battery reduces its service life. In the event of a defect in the electrical equipment of the machine, a maintenance-free battery may fail and will no longer be recoverable.

An article about how to choose a battery according to the car brand - important parameters and aspects when buying a battery. At the end of the article there is an interesting video about choosing a battery.

The content of the article:

Any motorist may face the problem of replacing a battery, whether he has a new car or one that already has a certain mileage. It is rare that the owner operates the equipment correctly, protects it from sudden temperature changes and overloads, and regularly monitors the condition of the battery. Therefore, not every battery reaches the end of its service life, and begins to show failures after 3-4 years.

Those owners who service their vehicles at a certified car service center are spared the need to look for a battery on their own. The service station specialists will install exactly the battery recommended in the instructions.

Although this service will be quite expensive for the driver, he will be confident in the reliability of the unit and the compliance of its technical parameters.

If the owner prefers to choose the battery himself, he should carefully read the recommendations of the manufacturer of his car, so as not to subsequently freeze in the cold while trying to start the engine.

Key parameters of batteries

Each car brand gives its own recommendations for servicing the models it produces, which can be read in the operating instructions.

The basic principles for choosing a battery based on body type and engine size are as follows:

• for hatchback and sedan cars with a 1.6-liter engine, batteries with a capacity of 45-55 Ampere/hour are suitable;
• for station wagons, with a volume of 1.3 to 1.9 liters, there are 60 Ampere/hour batteries;
• for SUVs and crossovers with 1.5-2.3 liter engines, at least 66 Ampere/hour is required;
• Trucks use batteries from 77 Ampere/hour or more.

Other indicators that you should pay attention to when purchasing a battery are as follows:

Rated voltage

If freight transport requires a powerful battery of at least 24 Volts, then 12-volt batteries are traditionally developed for passenger cars.

Battery capacity

One of the most important parameters when choosing a battery, as it shows the amount of energy that will be accumulated when charging. Its maximum volume is indicated on the body in the form of markings like “6ST-55”, where:

• the first digit indicates the number of batteries in the battery;
• the letters indicate the purpose, in this case, the starter battery;
• the second digit is precisely the capacity size in Amp-hours.

It is recommended not to chase a large volume, but to purchase a battery with the amount of energy that the car requires according to its technical parameters. Such a battery will not harm the car, but will not justify the investment in it.

Starting current

The amount of current supplied to the starter when starting the engine should be selected carefully and carefully. If it exceeds the level for which the starter is designed, its winding may burn out. If the power is insufficient, the starter will not start.

The starting current is not a stable value, as it depends on many related indicators: battery capacity, its charge level, quality of contact with the terminals, even air temperature. The starting current size is indicated on the battery label and is calculated at a temperature of +18 degrees.

Since in winter the current strength can decrease and the engine starts more slowly, it is allowed in particularly cold regions to purchase a battery a couple of tens of amperes higher than necessary in order to have a reserve in case of frost.

Some drivers have doubts about different current measurement standards. The fact is that its value can be indicated in the European equivalent EN, German DIN, American SAE or Russian GOST. To avoid confusion, you can ask the seller of a specialized store for a table of standards and select the required parameter.

Polarity

This indicator is important because if you select a battery with the wrong polarity, there may not be enough wires to fit onto the terminals.

Polarity - the position of the negative and positive electrodes - can be different:

• straight, when the positive terminal is located on the left;
• reverse, when, respectively, on the right.

This looks visually, for example, like this: 60 (1) Ah – left plus.
The terminals may also vary in thickness, since European ones have a standard thickness, but Asian ones will be significantly thinner. To ensure that the battery is securely attached and fits in size, it is important to take into account similar features of different manufacturers.

Manufacturer

• Exide- a world-famous company, a leader in this industry. The batteries he produces are very expensive, but they deserve it. Even under conditions of active use in any weather, for example, in a taxi service, such batteries will last at least 5-7 years;
• two German manufacturers - Varta and Bosch- ideally suited for their own automotive industry, where they serve for a long time without complaints;
• Medalist is a joint venture between the United States and South Korea, whose products are developed for Korean cars;
• Mutlu and InciAku- these are Turkish companies whose quality is at the highest level and is suitable for different car brands;
• Westa– Dnepropetrovsk plant producing mid-price batteries (Vortex, Forse);
• A-Mega is a Ukrainian manufacturer whose products are purchased by FIAT factories.

It is also worth mentioning such companies as the Slovenian Topla, the American American, the Belarusian Zubr, and the Russian Current Source Kursk.

For the domestic automobile industry, Russian batteries will be sufficient, whose performance is not much worse than imported analogues, but the cost is much lower.

Although in the context of rechargeable batteries, price really matters, since cheap batteries very often do not only last the required period, but do not even reach the end of the warranty. Since the battery is not the equipment on which you should save, it is better to give preference to reputable manufacturers.

Year of issue

The date of manufacture is printed on the battery case or on the label in the form of a simple numeric code or supplemented with letter and even color values. Each manufacturer labels products differently, but you only need to pay attention to the first group of numbers. Thus, the designation “0317 2 28674” will encrypt the date – March 2017.

Excessively large or insufficient battery capacity will one way or another affect the functioning of the battery itself. As mentioned above, there is a possibility of burning out the wiring and starter when the current is too high.

An excessively large battery capacity will lead to regular undercharging, since the generator will not be able to produce the voltage required to charge the battery.

Gradually, the electrolyte will turn white, the battery will discharge, and the engine will start getting worse and worse.

In the opposite situation, when the battery has a lower capacity, it will be overcharged, which will lead to short-circuiting of the batteries and shedding of the plates. In this case, a symptom of an incorrectly selected battery will be the darkening of the electrolyte to brown.

Since the battery is a warranty product, the seller is obliged to check it as much as possible before selling it to the client. Traditionally, the electrolyte level and voltage are measured, which should be at least 12 Volts.

After connecting the battery to the load plug, it should stably hold the load at 9A for 30 seconds, and the electrolyte should not boil or evaporate.

The warranty card itself must be filled out as much as possible with information about the product being purchased: brand, model, battery serial number, warranty period, signature of the seller and seal of the company that made the sale.

It is not recommended to purchase Chinese products, since according to practice and consumer reviews, they break down too quickly. If the battery appears too light in weight when you examine it, there is a good chance that the manufacturer has installed insufficient plates and lead.

Nowadays, the automobile market has too many low-quality products and outright fakes, so you will have to be very careful when choosing a battery.

Video about choosing a battery:

Greetings to blog readers! If you are planning to change your battery, our material will help you. On the one hand, in the open spaces of a boarding school you can easily select a battery based on the make of the car. On the other hand, not everything is so simple. Online selection will allow you to narrow down the range of models - the final choice still depends on the motorist. How to do it correctly - read our article.

Battery categories

All car batteries can be divided into three large groups:

• Maintenance free.
• Low maintenance.
• Serviced.

Serviced batteries, no matter how trivial it may sound, need to be serviced. If you do not add electrolyte to them, the battery will quickly fail. These are the cheapest batteries, with an average service life of about a year.

Low-maintenance batteries are essentially an improved version of maintenance-free batteries - you need to take care of them, but not so often. They work for 2-3 years.

Maintenance-free batteries have a sealed case that does not require periodic topping up of electrolyte. They can last up to 5-6 years, but cost 2-3 times more than conventional batteries.

The correct selection of batteries must take into account the method of maintenance.

Manufacturing technologies

The correct selection of batteries must take into account the manufacturing technology. All devices are divided into three groups:

1. Low antimony (Sb)- inexpensive, battery serviced. The disadvantages are low starting current and capacity. They break out quickly and require periodic topping up with distilled water. On the plus side, these devices are the cheapest and tolerate deep discharge well. There is no point in choosing them.
2. Calcium batteries (Ca\Ca)- more expensive than antimony ones, but significantly superior to them in characteristics. These car batteries are maintenance-free, hold a charge well, and have a high starting current and capacity. They can boast of a long service life. The downside is that they cannot withstand a full discharge. For example, 3-4 such discharges will lead to a loss of capacity by 70-80%. Those. The device can be safely thrown away.
3. Hybrid (Ca+, Sb\Ca, Hybrid battery)– devices have average characteristics and moderate cost. They tolerate deep discharges well. They belong to the underserved class.

The optimal choice of battery to purchase is calcium or hybrid batteries.

Ours or imported

The fundamental difference between European and domestic brands lies in standards. There are two of them:

1. ISO – for Europeans, for example Varta.
2. GOST - for Russian batteries, for example Tyumen.

And here, our producers feel much more at ease. According to ISO requirements, the maximum discharge current is applied to the battery for 30 seconds. During this time, the voltage on the battery should not drop below 9 V. And half a minute in extreme mode is a very good indicator.

GOST is less demanding - the test time is only 110-15 seconds. Those. Any battery can handle this. In defense of domestic production, it must be said that many manufacturers are improving product quality and also pass ISO. If this is the case, there will be a corresponding marking on the battery case.

Popular manufacturers:

• Bosch - all car enthusiasts know this brand. Durability, reliability, German quality and high cost. Here are the main characteristics of this company's products.
• Varta is a popular battery brand. The quality is not inferior to Bosch products, but much more affordable. The manufacturer pleases with a wide variety of models in its catalog. By the way, right on the company’s website there is an opportunity to online select batteries by car brand;
• ISTA car batteries- an inexpensive analogue of the Varta brand. Produced in Ukraine;
• car battery Tyumen- inexpensive, battery serviced. Analog – Titan.

According to reviews from motorists, they are quite decent options for your money.

Of course, the battery manufacturer is important, but the question of how to choose a battery does not end there.

Date of manufacture

Although the battery is not a sausage, it tends to deteriorate. The ideal option is to select batteries younger than 6-7 months.

If the battery is between 1 and 2 years old, this is a reason to ask the store for a significant discount. Why is that? The fact is that low-maintenance and maintenance-free batteries have a limited lifespan. And they need to be stored according to the rules - it’s not a fact that they are followed.

An interesting point - many people buy “aged” batteries in order to install it on the car they are selling. Those. a person buys a car with a new battery, but in fact it will soon die. Therefore, when buying a car, you should check the date of manufacture - the new appearance can be deceiving.

The selection of a battery for a vehicle should be based on the recommended capacity. This parameter indicates how long the battery will last under full load. Don't think that the larger the capacity, the better. The recommended value can be exceeded by 5-10 Ah. Let's find out why now.

By the way, the capacity is designated as follows:

• Amch;

Did you know that the highest percentage of car battery failures occurs in winter? The fact is that at sub-zero temperatures, the battery capacity can lose up to 40%. In addition, in winter the car starts worse. Those. at minus 20, the battery may give up. It is in such cases that a supply of capacity comes in handy.

So, we have decided on the capacity, but here the generator comes into play. You also need to pay attention to it when selecting a battery for a car based on the make of the car. The main task of this device is to provide energy to the car’s electrics and charge the battery while driving.

Let's look at an example using a VAZ generator. Its power is 80 A. Electrics consume 15-20% of the power, let’s set aside 5% for losses. Those. about 60 A remains for the battery. If you install, for example, 65-70 Ah, then such a battery will always be undercharged, which will shorten its service life. Hence the manufacturers' recommendations. By the way, many brands initially indicate a range of values, for example 55-60 Ah, for the same VAZ.

Inrush current, dimensions and polarity

There are several more parameters that need to be taken into account when choosing a battery:

• starting current – ​​means the maximum power supplied by the battery at a temperature of -18 °C in the interval of 3-30 seconds. The higher this value, the better;
• polarity - can be direct or reverse. To determine it, you need to look at the face of the battery. If the negative terminal is on the left, it is reverse, if on the right, it is direct.
• Dimensions – the greater the capacity of the device, the larger its dimensions. If there is a rigid battery stand under the hood, the device is larger in size and cannot be inserted.

Polarity does not affect the functionality of the device in any way. But if it is not correct, the length of the wires at the terminals may not be enough.

Battery check

There is a good saying - trust, but verify. No matter how good the battery is, no matter how much the seller praises it, the battery needs to be checked before purchasing. Otherwise, it can be excruciatingly painful later.

How to do this correctly? The seller should check it with a load fork in front of you. This procedure lasts 5-10 seconds. In this case, the voltage should not fall below 9 V. On the contrary, after a sag it begins to creep up. If the device shows 8 or 7 V, refuse to purchase.

Guarantee

The warranty period is another parameter that influences the choice of battery. There is no need to buy a battery if the manufacturer cannot guarantee its normal operation for at least 2 years. Some well-known brands have a warranty of up to 4-5 years, for example, for Varta batteries, it is 3-4 years, which is very good.

In fact, the guarantee is the estimated operating time of the battery. If it is 2+ years, this indicates that the manufacturer cares about the quality of the build and components.

Services for online battery selection

It is difficult for a novice car enthusiast to immediately understand all the intricacies of choosing a battery. Services for online selection of batteries by brand can make your life easier. The process itself is very simple; on the selection site you need to specify the following parameters:

• car brand;
• model;
• year of issue;
• engine's type;
• Some services may require a VIN code.

As a result, the system supplies suitable batteries. Because Most of these services belong to car stores - you can immediately select and buy the desired model.

Examples of services for online selection:

• http://akb-varta.ru/searchby— you can select a battery according to the car brand from the manufacturer Varta;
• http://www.koleso-russia.ru/batteries— a convenient service, in addition to the selected models, it issues a plate with the recommended battery characteristics. Among them are dimensions, starting current, capacity and, most importantly, minimum and maximum capacity;
• http://www.amag.ru/accumulator/select- another service where you can choose a battery for your car.

For example, a battery was selected for a 2010 Skoda Octavia with a 1.8 liter turbocharged engine.

Results:
