How does a battery work?

A car battery is a type of rechargeable battery that supplies electric energy to an automobile. It can be a SLI battery (Starting - Lighting - Ignition) to power the starter motor, the lights and the ignition system of a vehicle’s engine or a traction battery (used for the main power source of an electric vehicle). They are usually lead-acid batteries that provide a nominal 12-volt (actually 12.6 volts) potential difference by serially connecting six cells that each produces about 2 to 2.1 volts.

As other batteries of its type, it is made up of plates of lead and lead oxide. These plates are submerged into a 35% sulfuric acid and 65% water solution called the electrolyte solution. This process causes a chemical reaction that releases electrons, allowing them to flow through conductors thus producing electricity.

As a lead acid battery discharges, the materials of the lead plates react with the acid of the electrolyte, changing the surface of both plates to lead sulphate. When the battery is recharged, the chemical reaction is reversed. The lead sulphate reforms into lead oxide and lead, restoring the plates to their original condition, allowing the process to be repeated.

How to change a Battery?

In the vast majority of automobiles, the grounding is provided by connecting the body of the car to the negative electrode of the battery, a system called 'negative ground'. In the past this was different, some cars had 'positive ground', but such vehicles were found to suffer worse body corrosion and, sometimes, blocked radiators due to deposition of metal sludge. Care should be taken when changing acid as acid can have a negative effect on human skin.

When removing a car battery, the ground connection should be removed first and the other connection second. This ensures that a short circuit will not occur by a wrench touching grounded engine parts while disconnecting the other terminal. When connecting a battery, connect the live (or positive) connection first and then the grounded one. We are a car parts specialist so you’re in the best place for Car Batteries!
