Can an alternator drain my battery?

My battery keeps dying and I am struggling to find the culprit. Can my alternator drain my battery?

Nick Kunze · Updated on Mar 30, 2022

Reviewed by Shannon Martin, Licensed Insurance Agent.

A dying battery can be a really frustrating. A bad alternator can definitely drain your car’s battery.

The alternator charges your battery while the car runs, converting mechanical energy into electrical supply. A bad alternator may not charge your battery, leaving it with less power.

Even worse, a bad alternator can even drain your battery, even when the car is not running.

If you’re dealing with a bad alternator, it’s probably time to head to a mechanic.

While you’re waiting for your alternator to get fixed, why not take a few minutes to lower your

bill?
