Tips to Check Your Car's Battery

Car batteries last an average of three to four years, although, in harsh conditions, they can lose power before that time. Sometimes batteries are defective and fail while still in their warranty period. The only way to know whether your battery will hold a proper charge is to test it.

To test your battery, wear a pair of rubber gloves and safety eyewear to protect yourself from acid. Make sure the vehicle is off before connecting a voltmeter. Connect the red lead to the battery's positive terminal and the black lead to the negative terminal and take a reading. If the voltage is 12.2+ or 50 percent or a figure that is even lower, your battery is going bad and needs replacement.

Batteries can go bad for many different reasons. Bring your vehicle to the service department at Audi Birmingham for a full diagnostic evaluation of your battery.
