Battery Replacement: 2005 Scion tC 2.4L 4 Cyl.

Where is the battery located in a Scion tC?

The video above shows you how to replace the battery in your 2005 Scion tC. We recommend changing the battery in Scions 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 tC that you need to replace.

The battery location in a Scion tC 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 tC. See exactly where the battery is located in your 2005 Scion tC.

Replacing the battery in your tC involves removing the terminals. When you reconnect the terminals, your radio presets are likely to be cleared out. In some tCs, 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 Scion and they will give you the code for free. In many Scions, 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.
