Review: worked well - very good
Review: Outstanding product - I have a 1992 GMC Sierra 1500 pickup that I use for hunting, so i don't run it a lot. In order to keep the battery charged, i use a battery tender. But instead of clipping the tender to the battery I decided to use ring terminals and permanently attach the tender. Problem, the GM side terminals were not long enough. So i bought a pair of these extenders so i'd be able to easily attach the rinmg terminals of the tender.. The only 'hard" part of swapping over was getting the old studs out of the truck's cables. But after I used a 7/8 socket and channel-lock pliers they came right out (saw it on YouTube). The new extenders worked great, screwed right in my AAA-brand battery.. My battery tender is hooked up like i wanted.
