i dont know where some of yall get batteries for you tracking collars etc but the AA 3.6 volt batteries arent real easy to find around here. Radio Shack is the only place i can find them around here and they been giving me a thumping on them. i went to lookin around online today and found this place. they may have something yall need there.
