In this video, we will show you how to replace the 12V battery in your BMW i3. One of the first signs that your BMW i3 has to be replaced comes through through the instrument cluster which will display a "Battery discharging while stopped" message. Of course, you can always head over to your local BMW dealership to have the battery replaced, but some of us enjoy the DYI process. As always, this is just a guide and in no form or shape a recommendation to replace your own 12V battery. 

If you're still interested in doing the work yourself, our own Chuck put together a comprehensive video taking us through the entire process. We used the Remy 12V Battery AUX18L which costs around $140 and the iCar Pro OBD2 Diagnostic Interface. You'd also need the Bimmerlink App from the App store for iPhone/Android.
