How to choose a battery for a car?

Before answering the question: " How to choose a battery for a car?" - you should discuss the characteristics and parameters of the battery. Among them, the polarity, dimensions, battery capacity, the way it is fixed in the boot or luggage compartment, the type of terminal placement.

The battery for the car is one of the most important units. Let us consider in more detail its main elements.

Housing. It holds the content by combining all the elements. The casing should be strong and acid resistant, and also withstand high and low temperatures. The most popular material from which such devices are made is polypropylene. In the body cells are installed packets of plates, which consist of many plates with alternating polarity. They are made of lead and have a cellular structure for applying the active mass to it. This mass is the main reagent in battery operation. It is applied by smears, and therefore similar batteries are called batteries with plates of namaznogo type. Between the plates are separators, which prevent them from closing. Separators made of plastic that conducts the electrolyte are made. This design is in the assembled state in the bag and is tightened by a bandage. Thanks to the bandage, the plates can not be separated and their mutual displacement.

Capacity. Before choosing a battery for a car, you need to find out what kind of electric capacity it has. This parameter is measured in ampere hours (a / h). At the expense of energy for starting the engine, it increases in parallel with the increase in the battery voltage, as it takes longer to turn the starter. However, the acquisition of a larger capacity battery will not solve the problem with starting the engine in the cold season.

How to choose a battery for a car? First you need to pay attention to its polarity. He has two: reverse and direct. They are designated as plus and minus on the case.

If you choose a battery for the car by its brand, then you need to pay special attention to the location. In cars of American and Korean manufacture, the batteries are located as standard: in the engine compartment, to the right of the engine. The terminal wires are positioned so that the plus is on the left. In another case, the battery for the car will have to choose from Polish, Ukrainian and Belarusian.

How to choose a battery for a car in size, if they are unknown? You need to ask the sales consultant to tape measure and measure the dimensions, and then be guided by the sizes obtained. Attention should also be given to the battery holder.

It is important not only how to choose the battery for the car, but also how to extend the life of this unit. After all, the longer it lasts, the better. The basic condition for good performance of this device is the air temperature. And the lower it is, the worse it will be to penetrate the electrolyte between the pores of the plates. Because of this, the reaction speed is reduced, and the starting time of the engine is increased.
