Commonly Asked RX350L Battery Questions

Firestone Complete Auto Care has answers to your top car battery questions. If you have a RX350L-specific battery question, stop by your nearest store. Our expert techs have the answers you need.

  • Why won’t my RX350L battery hold a charge? A battery that won't hold a charge is almost as good as dead. The battery may be too old. Or, you may have been leaving your car doors ajar and the lights on overnight. Stop in for a free battery check at your favorite Firestone Complete Auto Care and get a handle on your car battery’s health.
  • What do you do with my old RX350L battery? We recycle it! Nearly 100% of all lead-acid batteries are recyclable.

  • 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 RX350L’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 RX350L 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 clean a corroded RX350L battery terminal? You can help prevent or get rid of corrosion by regularly inspecting and cleaning your battery terminals. Before cleaning your battery, see your RX350L 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.
