Where is a good place to buy a new battery?

... cheap?

I think mine is the original and it is Ka-PuT

Batteries plus, Iron pony, dealer, online.......etc.

I got a good buy on Shorai at MotoMummy.

If you have an interstate batteries near you call them up. Their econo-series are the cheapest batteries you can get and they usually come with a decent warranty.

If I were home I'd sell you my stocker pretty cheap...

Thanks for the ideas ... I like the Interstate idea.

I just ordered a battery from these guys last week and got it in 2 days.Free shipping
