Changing the battery in a Harley-Davidson Softail is a relatively simple matter of removing the seat and disconnecting the battery terminals. It should take no more than 30 to 45 minutes to complete the process.

Things you need

  • Phillips-tip screwdriver

  • SAE hex wrench set

  • 10-mm open-end wrench

Turn off the ignition. Unscrew the seat fastener located on the top of the rear fender with a Phillips-tip screwdriver.

Loosen and remove the two large bolts located on the lower left and right undersides of the seat with a large SAE hex wrench.

Slide the seat toward the rear of the bike while lifting it up and away.

Unbolt the negative battery cable with a 10-mm open-ended wrench. Do the same with the positive terminal.

Disconnect the rubber battery strap. Lift the battery out of its tray.

Install a new battery in reverse order.

Tips
