Where is the battery located in a Jeep Wrangler?
The video above shows you how to replace the battery in your 2012 Jeep Wrangler. We recommend changing the battery in Jeeps every 4 years. Although some batteries last much longer, most batteries begin breaking down chemically after four years, so you could experience dimmer headlights and other negative effects before you have a dead battery in your Wrangler that you need to replace.
The battery location in a Jeep Wrangler can typically be found in the engine bay, but may be in the trunk, fender or inside of the vehicle. You may need to remove the air filter housing, a plastic engine cover or parts of the cowl to find the battery in your Wrangler. See exactly where the battery is located in your 2012 Jeep Wrangler.
Replacing the battery in your Wrangler involves removing the terminals. When you reconnect the terminals, your radio presets are likely to be cleared out. In some Wranglers, you may need to re-enter a security code to get your radio to work again. Check for this code in your owners manual - it will usually be either a sticker or small card in the booklet. If you can't find it, call Jeep and they will give you the code for free. In many Jeeps, the transmission "learns" how you drive over time and makes adjustments, so you may experience altered driving dynamics as your car re-learns your driving style after changing the battery.
