Top Ascent Car Battery Questions

Firestone Complete Auto Care has answers to your top car battery questions. If you have a Ascent-specific battery question, pay us a visit. Our technicians have the answers.

  • Why won’t my Ascent battery hold a charge? 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 free battery test at your local Firestone Complete Auto Care to learn more about the state of your battery.
  • What do you do with my dead Ascent battery? We’ll recycle your car battery for you!
  •  How much do DieHard batteries cost for your Subaru Ascent? You can find affordable Ascent batteries by using one of our car battery coupons, when available. Plus, every DieHard battery comes with extra coverage thanks to DieHard Assurance and a free replacement warranty.
  • How long can I expect my car battery to last? The typical 12-volt car battery may last three to five years, depending on the type of battery, the driving conditions, and how well the battery is maintained.
  • What is the white, crusty substance accumulating on my Ascent’s battery post? The white, crusty stuff that can accumulate around Ascent car battery terminals is called corrosion. It is caused by a chemical reaction between the battery acid and the air, which creates a white, powdery substance that can build up on the terminals over time. Corrosion can interfere with the flow of electricity between the battery post and the car's electrical system, sometimes leading to poor electrical performance, difficulty starting, and even premature battery failure.
  • How do I remove corrosion from my Ascent 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 Ascent 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.
