Automotive Battery Replacement

Batteries

An automotive battery is a type of rechargeable battery that supplies electric energy to an automobile. Usually this refers to an SLI battery (starting, lighting, ignition ) to power the starter motor, the lights, and the ignition system of a vehicle’s engine. Automotive SLI batteries are usually lead-acid type, and are made of six galvanic cells in series to provide a 12 volt system. Each cell provides 2.1 volts for a total of 12.6 volt at full charge.

Lead-acid batteries are made up of plates of lead and separate plates of lead dioxide, which are submerged into an electrolyte solution of about 35% sulfuric acid and 65% water. This causes a chemical reaction that releases electrons, allowing them to flow through conductors to produce electricity.

As the battery discharges, the acid of the electrolyte reacts with the materials of the plates, changing their surface to lead sulfate. When the battery is recharged, the chemical reaction is reversed: the lead sulfate reforms into lead oxide and lead. With the plates restored to their original condition, the process may now be repeated.

The average life of a car battery is between two and five years. Life expectancy varies by where you live. It ranges from fifty-one months in extremely cold areas to just thirty months in extremely hot climates.  Another consideration is how frequently you drive short distances and how often you keep your gadgets plugged in.  The battery will drain faster if you regularly drive for 20 minutes or less. This does not allow your battery to fully charge. Try your best to keep these short trips to a minimum.
