Where is the battery located in a Smart Fortwo?
The video above shows you how to replace the battery in your 2008 Smart Fortwo. We recommend changing the battery in Smarts 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 Fortwo that you need to replace.
The battery location in a Smart Fortwo 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 Fortwo. See exactly where the battery is located in your 2008 Smart Fortwo.
Replacing the battery in your Fortwo involves removing the terminals. When you reconnect the terminals, your radio presets are likely to be cleared out. In some Fortwos, 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 Smart and they will give you the code for free. In many Smarts, 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.
