Top C320 Car Battery Questions

Firestone Complete Auto Care has answers to your top car battery questions. If you have battery questions that are Mercedes-Benz C320-specific, pay us a visit. Our technicians have the answers.

  • Why won’t my C320 battery hold a charge? A battery that won't hold a charge is almost as good as dead. The battery might be old. Or, you may have a habit of leaving your car doors open and the lights on overnight. Stop in for a free battery check at your local Firestone Complete Auto Care and get a handle on your car battery’s health.
  • What do you do with my old C320 battery? We recycle it! Nearly 100% of all lead-acid batteries are recyclable.

  • 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 C320’s battery post? A chemical reaction between battery acid and the air can cause a white, crusty buildup to form on the terminals of your C320 car battery. This buildup — known as corrosion — can impede the flow of electricity and cause a range of issues, from poor performance to premature battery failure.
  • How do I remove corrosion from my C320 car battery? To help extend the life of your battery, you should routinely inspect and clean the terminals using a baking soda and water mix, wire brush, and rag. Be sure to disconnect the battery cables before cleaning and check your C320 owner’s manual for instructions on how to do so.
