How Do I Remove a Battery from a BMW R1100RT?

by Chris Gilliland

BMW's R1100RT touring motorcycles are well suited to the sometimes extreme environments encountered during a long road trip. However, the battery that powers the R1100RT's electrical system can lose its charge over time, rendering the motorcycle completely useless. Removing a dead battery can be a task that many R1100RT owners dread, as the battery is hidden within the heart of the machine. While some disassembly is required, accessing and removing the battery is a task that can be accomplished within 15 minutes.

Step 1

Locate the seat-release lock under the tail light. Unlock the seat with the ignition key and pull it off the motorcycle's frame.

Step 2

Remove the bolts from the left-middle fairing with an Allen wrench. Remove the left-middle fairing from the motorcycle to reveal the battery tray on the left side of the fuel tank.

Step 3

Pull the rubber retaining strap off the battery tray. Remove the negative wire lead bolt from the battery with a Phillips screwdriver. Pull the negative wire lead away from the battery and the motorcycle's frame. Pull the battery out of the tray until the positive wire lead is accessible. Remove the positive wire lead bolt from the battery with a Phillips screwdriver. Pull the positive wire lead away from the battery.

Pull the battery out of the battery tray.
