I'm not sure what battery came from the factory on that bike but all here use a few different choices for a battery. You will need a minimum of 310cca.

I use an HD battery:
65989-97C
This battery is 315cca. I've used this one on all my Big Dog's with no issues.

You can also check out some great choices in batteries at Wild Steed Worx .com

I want to share my recent experience with cheap Chinese Lithium battery.(H.D. battery was still cheaper by about 70 dollars)
So I put the battery in and started the bike three or four times - it cranked the motor better than
my old battery - all good I thought but when I took the bike for a very short spin (lucky it was short)
it has fried my voltage regulator and burned my headlight globe. When I parked the bike in my garage the volt meter was showing over 17 volts on the battery while motor was idling.
Now I have a new regulator and a H.D. battery in there and that is what I will be putting in my bike from now on!

What ever you do, if you buy a new battery. I always suggest you put it on a charge for several hours before using it. By charge, I mean charger not tender! Don't just slap it in the bike and start cranking.

I went with the Duracell this time 310ca never on the charger this summer. It has set for a week or so with no problems starting. This winter it will be on the charger. First of spring it will be a year old. We shall see.

If its a battery that you add the juice to it, you know it wasn't sitting on a shelve for a year before you get it. The ones you add the juice to, tell you to let it stand for an hour or 2 so the fluid can absorb into the matting, then charge it but don't use a charger with more than 2.0 AMPS the 1st time you charge it.
