Questions & Answers
How long do car batteries last?
A typical car battery lasts 3 to 5 years. Get the most out of your battery by keeping your battery charged, terminals clean, and by properly maintaining your starting and charging system.
How to tell if a car battery is dead?
There are signs you can use to diagnose this issue, most notably a slow start or electronics that work until you try to start the engine. If you want to know for sure, you should bring it to your local AutoZone for a free battery test.
Can I test a battery with a multimeter?
Yes. Ensure the battery hasn't been used for an hour and set the multmeter to DC voltage. Touch the probes to the corresponding terminals. You should see 12.66 volts ideally, and at least 12 if there is any charge.
How to jump start a car battery?
Connect the red clamps to the positive terminals, first on the dead battery, then on the live one. Connect a black clamp to the live battery's negative terminal and the other to ground. Start the working car, then try starting the other car.
Are car batteries universal?
No. Car batteries are different from vehicle to vehicle. Enter your vehicle's info at the top of this page to find the battery that meets your vehicle's specifications.
Does a dead battery always need to be replaced?
Not necessarily. Your battery may be discharged due to a faulty part in the charging system, like an alternator. This is why it is smart to bring yours in for a free battery test at your local AutoZone to determine exactly what needs to be done.
How do I keep my battery charged if I don't drive often?
Not driving frequently can result in a dead battery because it needs to be recharged by the alternator, which happens when you drive. If you spend long periods of time not driving your car, consider using a battery maintainer to keep yours charged.
