Hey! That is a MYTH about putting the battery on the concrete and loosing the charge. The battery case is plastic and plastic does NOT transfer any current at all. Even the "Mythbusters" tested and busted this myth! Looks like back to science class for some...
Rusty is 110% correct,urban legend,myth or ignorance,call it what you want,storing batteries on concrete has 0 effect,my brother works for Interstate and they store 1000's of batteries on the ground,it's plastic,basic electricity 101,plastics does not transfer electricity.
A neighbor came over to look at my RoadKing and said I should put a piece of rubber under the stand when it is parked in the garage.He said that the jiffy stand will slowly drain the battery acting as a ground. Sounds kind of strange to me, but ?????
I was told that same thing when I picked up my RoadKing that is why I changed my jiffy stand from the metal one to a wooden one. If this is not truethen should I change it back.
