Jeep Wrangler JK Car Battery

Each Jeep Wrangler JK depends on a 12-volt battery to operate accessories and to start the vehicle. When the battery goes bad, the Jeep won't start any longer. If you notice your Jeep struggling to start, or your radio or lights aren't working properly, you likely have a worn battery that needs replacing. AutoZone has Jeep Wrangler JK batteries that are easy to select and install from top brands like Duralast and Optima.

Symptoms of a Bad Battery

As batteries go bad in a Jeep Wrangler JK, the vehicle won't start easily. Cranking takes longer, and you may hear a clicking noise on startup. You may also notice the battery has a bulging case and looks swollen. AutoZone offers the right size battery based on the year, make, model, and engine size of your vehicle.
