That's right, walmart did carry them. Long before the ".com" shopping. I keep wanting to think rayovac made them??
U r correct on the brand. My dad n i each had 1 in case we needed to split up n flush the game towards 1 another. Our burned up in a house fire 5-6yrs ago and hadnt even givin them a sec thought till this post. We would take 2 6vdc square top batts n connect them for high amp output, but stayin at 6vdc.
