How to Replace the Battery on a Vulcan Motorcycle

by Chris Gilliland

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.

Step 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.

Step 2

Unplug the electrical connectors on both ends of the battery between the motorcycle's seat rails.

Step 3

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

Step 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.

Step 5

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

Step 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.

Reassemble the motorcycle by doing the steps in reverse.
