    Frequently Asked Questions

    What is a car battery and what does it do?

    A car battery is a rechargeable battery that powers your vehicle’s electrical systems, including the starter motor, ignition system, and other accessories. It stores energy generated by the alternator while the engine is running and provides a temporary source of power when the engine is off. A car battery is typically made up of lead plates and acid, and it can be replaced if it becomes damaged or worn out.

    How does a car battery work?

    A car battery works by converting chemical energy into electrical energy. When the engine is running, the alternator charges the battery, replenishing the energy that is used to start the engine. The battery also provides a temporary source of power to the vehicle’s electrical systems when the engine is off. The battery’s voltage is typically around 12 volts, and it has a capacity measured in ampere-hours (Ah) or cold cranking amps (CCA).

    Why should I replace my car battery?

    You should replace your car battery if it is no longer holding a charge, is leaking acid, or is more than three to five years old. A failing battery can leave you stranded or cause other electrical problems in your vehicle. Replacing your battery with a new one can improve your vehicle’s performance, reliability, and overall safety. Additionally, a new battery can provide better starting power and a longer lifespan.

    How do I know if my car battery needs to be replaced?

    You can check if your car battery needs to be replaced by looking for signs of wear and tear, such as cracks, corrosion, or swelling. You can also test the battery’s voltage and capacity using a multimeter or a battery tester. If the battery is not holding a charge or is not providing enough power to start the engine, it may need to be replaced. It’s also a good idea to replace your battery if it is more than three to five years old, even if it seems to be working properly.
