How do car batteries work?

Batteries in general consist of cells. These cells are the place where chemical energy is stored. Then, these cells transform the energy into electricity that is used to power the electronic device.

In case of car batteries, they belong to a category called “SLI”, it stands for starting, lighting, and ignition. SLI batteries are responsible for running car engines in addition to powering lights and other accessories.

An SLI battery contains 6 cells, each of them has 2 grids, a grid made from lead and another one made from lead dioxide. Every cell provides 2 volts of energy. So, the battery totally provides 12 volts of energy.

A sulphuric acid is used as a trigger for the reaction between the 2 grids, this reaction produces ions and lead sulphate.Ions react to the adjacent grid to provide hydrogen with lead sulphate. This chemical reaction produces electrons that finally generate electricity.

The generated electricity passes through terminals of the battery to run the engine, power the lights, and run other accessories.


How long do car batteries last?

In ideal conditions while there is no high temperature or excess humidity, you can expect the life of your car battery to last up to 6 years. But, the average life of car batteries in the existence of affecting factors is from 2 years to 5 years.
