How to Replace the Battery on a Kawasaki Vulcan Motorcycle

Motorcycle batteries are fairly reliable and, if treated right, can last for many years. But even the best batteries must be replaced eventually, a process that can be a bit challenging to a Kawasaki Vulcan owner. The battery is housed under a metal lid that contains several of the motorcycle’s electrical connections. Only a few tools are needed to free the old battery and replace it with a new one, making this a job that you can tackle within a short period of time


1) Unscrew the bolt under the sides and at the rear of the seat, using a 10 mm socket. Pull the seat toward the rear fender to slide the tab on the front of the seat out of the motorcycle’s frame. Set the seat aside.

2) Unplug the electrical connectors on both ends of the battery between the motorcycle’s seat rails.

3) Unscrew the bolts from the center of the battery cover, using a 10 mm socket. Lift the cover off the battery.

4) Unscrew the terminal bolt from the battery’s negative terminal with a Phillips screwdriver. Pull the black cable off the battery. Unscrew the battery’s positive terminal bolt with a Phillips screwdriver and pull the cable away.

5) Lift the battery out of the battery tray and replace it with a new battery.

6) Connect the battery cables to the battery, connecting the positive cable followed by the negative cable. Screw the terminal bolts into place with a Phillips screwdriver.

7) Reassemble the motorcycle by doing the steps in reverse.
