Commonly Asked Sigma Battery Questions

Firestone Complete Auto Care has answers to your top car battery questions. If you have battery questions that are Mitsubishi Sigma-specific, visit your nearest store. Our technicians have the answers.

  • Why doesn’t my Sigma battery stay charged? A car battery that needs to be jump-started every time is as good as dead. The battery may be too old. Or, you’ve been leaving the doors slightly open and the dome lights on during the night. Stop by for a complimentary battery check at your favorite Firestone Complete Auto Care to learn more about the state of your battery.
  • What do you do with my old Sigma battery? We recycle it, taking care of both your car and the Earth.
  • How much will replacing my Mitsubishi Sigma’s battery cost if I get a DieHard battery? Mitsubishi Sigma batteries can be affordable, especially when there's an available battery coupon. The best part is every DieHard battery comes with a free replacement warranty and extra coverage with DieHard Assurance.
  • 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 substance accumulating on my Sigma’s battery post? The white, flaky stuff that can build up around your Sigma’s battery terminals is known as corrosion. Acid leaking from your vehicle’s battery post can have a chemical reaction with the air, leading to an accumulation of the white, powdery substance over time. Corrosion can affect the flow of electricity between your battery and the electrical system in your Sigma, possibly causing issues with electrical performance and starting. If left unaddressed for long enough, it may even cause your battery to prematurely fail.
  • What do I do about corrosion on my Sigma car battery? You can help prevent or get rid of corrosion by regularly inspecting and cleaning your battery terminals. Before cleaning your battery, see your Sigma owner's manual to learn how to disconnect the battery cables. After disconnecting the cables, use a mixture of water and baking soda, a wire brush, and a rag to carefully clean the terminals.
