Setting a car battery on concrete?

From searching on the intraweb, it appears the argument is supposedly it would ground the battery and cause it to lose a charge, but of course that is false.

Actually the reason the idea came about is when batteries were encased in rubber many years ago, the rubber would start to crack and the electricity could jump through to the ground. Course nowadays they are made with plastic, so that won't happen.
 
It doesn't. From having worked in an autoparts department, I think the reason that myth still persists is because of people who store batteries over the winter on concrete in garages and don't maintain them, or allow them to freeze or experience rapid changes in temperature, etc. Then when they come back to them in the spring, the battery is dead and unable to maintain a charge.


...of course, in Florida you don't really have winter...or freezing...
