I get mine at Wally World. They are well priced, have a good warranty, and you can find a Walmart almost anywhere you are in the country if one goes bad. Other than that I hate Walmart though.
I agree Slimey. I had one go bad Sunday and the guy with the earring at Columbus Walmart hooked me up on a warranty on 3 year old battries. Only ketch was, I had to give em DD's phone number. Cheap price to pay to save bout $50. Thanks dd.
