How Can I Take Care of My Battery?

Extend the life of your car battery with these simple battery care tips from America's #1 replacement battery, Interstate Batteries:

  • When you clean your car, clean your battery. Corrosion and debris can accumulate around the battery terminals and prevent your car from getting the charge it needs. When you run your car through the wash, remember to clean your battery terminals too. This can be done with baking soda or a corrosion remover.
  • Get your battery tested early and often. Save yourself from an expensive tow or repair bill down the road by getting your battery tested every six months. You can also conveniently check your battery life online using our Virtual Battery Tester below!
