Myth or Fact

Posted by Randy Gross on June 12, 2005, 11:38 pm

I was charging my auto battery today outside the apt. on the concrete
stoop. A passer-by told my wife that the battery sitting on the
concrete would drain the battery.

I've charged a lot of batteries over the years, a lot on concrete, with
no problems at all.

Myth or Fact?

Storing batteries for long periods of time on concrete in places where
the air temperature can vary greatly from that of the floor (garages,
basements) can set up thermal (and thus electrical) gradients across
the battery and cause the self-discharge rate to increase
dramatically. Charging on concrete isn't a problem.
