How do you replace the battery for a heritage softail?

To replace the battery on a Harley-Davidson Heritage Softail, first, ensure the motorcycle is turned off and the keys are removed. Remove the seat by unscrewing the bolts or fasteners, then disconnect the negative (-) terminal followed by the positive (+) terminal from the old battery. Take out the old battery and install the new one by connecting the positive (+) terminal first, then the negative (-) terminal. Finally, reattach the seat and ensure everything is secure before starting the bike.
