Buy the Right Battery for Your Buick LeSabre

Sadly, your Buick LeSabre won't last forever. Neither will its battery. On average, auto batteries last anywhere from three to five years. Check your battery regularly and replace it as needed so it doesn’t leave you and your Buick LeSabre stranded. Watch for signs that your current battery is getting too old or too weak. A slow engine crank, an illuminated battery or check engine light, swollen battery case, corroded battery posts, or dim headlights can all be signs that your battery is on its last leg.

  • Why doesn’t my LeSabre battery stay charged? A battery is in its final hour when it will no longer hold a charge. The battery might be old. Or, you may have been leaving your car doors ajar and the cabin light at night. Stop in for a free battery check at your nearest Firestone Complete Auto Care and learn more about your battery's charge.
  • What happens to my old LeSabre battery? We recycle it! Nearly 100% of all lead-acid batteries are recyclable.

  • What is the average lifespan of a car battery? 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.
  • Why is there white, flaky stuff around my LeSabre’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 LeSabre 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 LeSabre 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 LeSabre 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.
