Why doesn’t my Cutlass Supreme battery stay charged?

A battery that won't hold a charge is almost as good as dead. It may be getting old. Or, you’ve been leaving the doors slightly open and the dome lights on during the night.

How long can I expect my car battery to last?

You can usually get three to five years out of your car battery. However, battery type, how well you maintain your battery, and your driving habits can all affect your battery’s lifespan.

What is the white, crusty stuff around my Cutlass Supreme’s battery post?

How do I clean a corroded Cutlass Supreme battery terminal?

Regularly inspect the terminals and clean them with a mixture of baking soda and water, a wire brush, and a rag.
