How to Change the Battery on a BMW R1200C
1. Unscrew the three bolts holding your BMW's gas tank in place. The bolts are located on both sides and at the front of the gas tank. Use an Allen key wrench to remove the bolts.
2. Prop the gas tank up to give you access to the battery compartment or have an assistant hold the gas tank as you work with the battery.
3. Pull the battery from the compartment underneath the gas tank to access the battery's terminal access points. The terminals point towards the ground.
4. Remove the wires connected to the terminal access points by hand, starting with the negative (black) terminal wire.
5. Attach the wires to the terminal access points of the new battery by hand, starting with the positive (red) terminal wire.
6. Install the new battery into the battery compartment with the terminals facing towards the ground.
7. Reattach your BMW's gas tank by first installing the front screw and then the side screws.
