  • Why doesn’t my Wrangler JK battery stay charged? A battery is in its final hour when it will no longer hold a charge. The battery may be too old.

  • What do you do with my old Wrangler JK battery? We recycle it! Nearly 100% of all lead-acid batteries are recyclable.
  •  How much do DieHard batteries cost for your Jeep Wrangler JK? Jeep Wrangler JK 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 do car batteries last? A car battery normally lasts three to five years, but this number can vary based on battery type, your driving habits, and battery maintenance.
  • Why is there white, flaky stuff around my Wrangler JK’s battery post? The white, crusty stuff that can accumulate around Wrangler JK 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 clean corrosion off my Wrangler JK vehicle battery? You can help prevent or get rid of corrosion by regularly inspecting and cleaning your battery terminals. Before cleaning your battery, see your Wrangler JK 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.
