Car Battery Replacement

Replacement Batteries and Electrical Help from AutoZone

What is a car battery?

A car battery is the heart of the vehicle's electrical system. It supplies electric energy to a vehicle and is rechargeable. It powers the ignition system of the vehicle, as well as the lights and other peripherals.

How do I know it's the car battery that's bad?

In addition to the battery warning light staying on for an extended period, the battery may need to be replaced if the motor turns over slowly or in an interrupted manner when the ignition is turned on, or if the vehicle doesn't start at all. Losing power quickly in cold weather or dim headlights when the vehicle is idling are also signs that the battery is dying. A voltmeter or hydrometer can be used to test the battery.
