Q: Dead battery

asked by on

My battery is dead.

Once the battery is replaced, have a trained technician, like one from YourMechanic perform a charging system test to make sure the alternator is charging the battery. If the alternator is not charging the battery the battery will run down again. These tests will let you know if you need to replace the alternator or the battery.
