Re:Was discharge rate for stored battery- Now Battery Care

[turbodmc@xxxx]

Never store on concrete-put it on a 
piece of wood. (I don't know why but it will discharge faster if left 
directly on concrete.)

This is not an urban legend; it is true even though it seams to defy 
basic laws of electric/chemistry.

Most batteries are in the engine compartment thus they get dirty. The 
dirt on the battery forms a conductive path (it is a very high 
resistance thus it is small but a conductive path all the same). The 
concrete is also somewhat conductive so by putting the battery on a 
conductor you are exacerbating this problem. If the battery is clean 
(as David recommends) then putting it on a piece of wood (and 
insulator) is really not critical. For those of you who enjoy useless 
and trivial information I hope that helps.

One of the best things I have found for car / battery storage is a 
float charger. They run from $10 to $50 and they keep the battery 
toped off at all times (without cooking it) which will give you the 
longest battery life. It also will cover the ma amp draw that the 
batter has from clocks, alarm systems etc and has the added advantage 
of keeping the memory on your radio, clock and computer.
