A car battery is a standard energy supply that can’t be looked over. The modern technological achievements have led to the creation of more durable and dependable batteries that may be applied for longer periods of time. This is not to say that every brand has achieved a similar level of success in designing their products. Car owners simply don’t have the time to look into advantages and disadvantages of every brand and they seek only a more affordable product.
Some car batteries come with exclusive features and it would be a disappointing if a customer would have read about them after he had bought a model with lesser capabilities.
A comprehensive analysis of technical specs, pros and cons and general overview from customers will help you understand which product is more suitable for your car.

Types of Car Batteries
First of all, it is necessary to explore the properties of different kinds of batteries. The most often used one is the lead-acid type. The battery itself consists of 6 cans, each with a rated voltage of about 2.2 volts, connected in series. A common electrolyte is a combination of distilled water and sulfuric acid. The resistance to low temperature grows with the density of the electrolyte.
AGM technology makes use of a porous fiberglass body compartment filled with a liquid electrolyte. The micropores of this material are not completely filled with electrolyte. The free volume is used for the recombination of gases.
Batteries, manufactured using AGM technology, are manufactured in a spiral or flat configuration. A series of products with a spiral construction of blocks is produced mainly in North America, and with a flat configuration of electrodes – in North America and in Europe. Spiral elements have a larger surface contact area, which makes it possible to quickly produce higher currents and charge faster. However, the flip side is the reduction of the specific capacity of the battery (the ratio of electrical capacity and size) compared with a flat configuration. Both technologies are quite promising. Currently, AGM with a flat block configuration are the most widespread car power sources.
Advantages
The battery manufactured by AGM technology has a number of advantages over classic batteries, derived from this technology. In particular, resistance to vibration, less maintenance work, installation in almost any position (installation upside down is not recommended for safety reasons due to the location of the valves). Some manufacturers claim increased performance of such batteries or high starting current.
- Sealed design prevents acid leakage and corrosion.
- Risk-free functioning: with proper charging of the batteries, the possibility of gas emissions and the risk of explosion are eliminated.
- Works well at any conditions, withstanding the temperatures of –30 °С (lower than that crystallization of the electrolyte of a discharged battery is possible and, as a consequence, this reduces the battery life due to damage to the active surface).
Lead-acid battery is popular due to its reasonable price, decent durability (from 500 cycles and more) and high power density. The main areas of application are: starter batteries in vehicles, emergency sources of electricity, back-up sources of energy.
The element of a lead-acid battery is made of electrodes and separating porous plates consisting of a material that does not interact with the acid and prevent the electrodes (separators) from closing, which are absorbed in the electrolyte. Electrodes are flat gratings made of metallic lead. Lead dioxide (PbO2) powders in the anode plates and metallic lead in the cathode plates are pressed into the cells of these grids. The use of powders increases the electrolyte-solid interface, thereby increasing the electrical capacity of the battery. Distilled water is used for the production of the acid solution.

As the ambient temperature decreases, battery parameters get worse, however, unlike other types of batteries, this decrease is relatively small in lead-acid batteries, which causes their widespread use in transport.
A discharged battery in temperatures below zero can swell due to the freezing of a low-density electrolyte and the formation of ice crystals, which leads to irreversible damage to lead plates inside the battery.
- at temperatures from 0 ° C to –10 ° C, a decrease in charging and discharge characteristics does not significantly affect the performance of the battery;
- at temperatures from –10 ° C to –20 ° C, the current in the starter mode decreases and the charge diminishes.
- at temperatures below −20 ° C, rechargeable batteries do not provide a reliable start of the engine and are not capable of receiving charge from the generator.
Because of the greater internal resistance inherent in modern closed-type batteries (the so-called “maintenance-free”) at low temperatures compared with conventional batteries (open type), these questions are even more relevant for them.
How to Choose the Right Battery for Your Vehicle ?
Every car owner has to be aware of battery parameters and choose it in accordance with the particular vehicle requirements. We will take a look at basic parameters.
The Size
Every battery produced by different manufacturers has its size and weight, you need to be aware of what exactly you need.
Power Requirements
- 6V batteries were used until the end of the 40s of the 20th century. Almost all cars had six-volt electrical equipment. Currently, batteries with a voltage of 6 V are used only on lightweight motorcycles.
- 12V batteries are used on the vast majority of cars, trucks
and buses with gasoline engines, as well as on most motorcycles. - 24V
are used on heavy trucks and buses with diesel engines, trolley buses, trams, and military equipment with diesel engines.
On light-duty trucks, minibuses and passenger cars with diesel engines, batteries with an electrical voltage of 12 volts are used.
Freshness
Car owners do not need to acquire a battery that is older than 6 months from the date it was produced. This is written on the battery through the use of a letter and a number. For example, C/3 stands for March 2003. It can be identified in the case of the battery.

Car Battery Maintenance
Lead-acid batteries should only be stored in a charged state. At temperatures below −20 °C, the batteries must be recharged with a constant voltage of 2.45 V/cell once a year for 48 hours. At room temperature – 1 time in 8 months with a constant voltage of 2.35 V/cell for 6-12 hours. Storage of batteries at temperatures above 30 °C is not recommended. When batteries are stored for a long time and are discharged by large currents (in starter mode), or when the capacity of batteries is reduced, it is necessary to conduct control and training cycles.
- Correctly and fully charge the battery.
- Apply plastic grease (
lithol , grease, etc.) to the positive terminal of the battery, as the electrolyte film is capable of absorbing moisture from the atmosphere, which can lead to increased self-discharge. - Store batteries in the cold, as at low temperatures self-discharge is much lower. The electrolyte of a fully charged battery begins to freeze at temperatures below −55 C.
If it is necessary to travel in cold weather, the battery should be transferred to a heated room and within 7–9 hours (for example, overnight) it will come to a condition suitable for starting the engine.
Car Battery Warranty
The price and quality are factors that usually suggest the approximate active period of a car battery. They come with 1, 2 or 3-year guarantee. It would not be surprising for a 1-year warranty battery to stop functioning much sooner than those with longer period of warranty.
