How do you replace a batter on a Harley Davidson Ultra Classic?

On models similar to the 2007 Electra Glides, the battery is under the seat. You'll need a Philips screw driver for the seat screw, and a torx driver (preferably a wrench cuz you can get more torque on it) to remove the battery retaining clamp. Also a small wrench (size???) to remove the battery cables. It's pretty straightforward once you get the seat off and can see it. Just be careful to get everything back in it's proper place and put the insulator back on the positive cable so nothing rubs or shorts out when you put the seat back on and are riding down the road.
