  • Amp-hour rating: The amp-hour rating (AH) is a measure of how much power the battery can store. The higher the AH rating, the longer the battery will last between charges.
  • Price: Batteries can range in price from a few dollars to a few hundred dollars. You’ll need to decide how much you’re willing to spend on a battery.

How to Install a New Battery

Installing a new battery in your Road King is a relatively simple task. Here are the steps involved:
