jimmer Posted May 3, 2010 Report Share Posted May 3, 2010 Can some one clarify whether storing a battery on concrete kills the battery or is this a myth? Link to comment Share on other sites More sharing options...
Jer Posted May 3, 2010 Report Share Posted May 3, 2010 I believe it'a a myth. It's more of an issue that if the battery leaks in any way, it will eat the concrete. Link to comment Share on other sites More sharing options...
Syn Posted May 3, 2010 Report Share Posted May 3, 2010 That was true long long ago with rubber case batteries, not today. Link to comment Share on other sites More sharing options...
Roy Posted May 3, 2010 Report Share Posted May 3, 2010 It's a myth, Jimmer. It was true 100 years ago when batteries were made of porous materials....not today. Link to comment Share on other sites More sharing options...
Nipfisher Posted May 3, 2010 Report Share Posted May 3, 2010 I keep mine on a shelf all winter as I was told it was the COLD concrete that drained the battery. Link to comment Share on other sites More sharing options...

Fisherman Posted May 3, 2010 Report Share Posted May 3, 2010 I keep mine on a shelf all winter as I was told it was the COLD concrete that drained the battery. I have some mountain property for sale in Florida, real cheap. Now you know which battery guy to stay away from, he's full of it. Link to comment Share on other sites More sharing options...

You got a good memory from when you were a teenager. But yes the battery guru's have debunked the concrete issue years ago. Art Link to comment Share on other sites More sharing options...

Art Oh hell yeah art! why, even Woodrow Wilson was a pal of mine just before his death in 1924. He'd regularly write for advice on the German/Mexican alliance in WW1. And it was an easy fix...I told him to put both Germany and Mexico on ModQ and he was forever grateful. Link to comment Share on other sites More sharing options...
John Bacon Posted May 4, 2010 Report Share Posted May 4, 2010 I keep mine on a shelf all winter as I was told it was the COLD concrete that drained the battery. COLD is good for the battery. One of the benefits of storing a battery on a concrete floor is that it will help keep the battery cooler which prolongs the life of the battery. Keeping it charged is the most important thing.

fishhunter Posted May 4, 2010 Report Share Posted May 4, 2010 100% myth Link to comment Share on other sites More sharing options...
POLLIWOGG Posted May 4, 2010 Report Share Posted May 4, 2010 In the days when you could go into a garage and find a cat sleeping in the old oil stove the floor was never above freezing in the winter and if you put a warmer battery on the cold floor it would weaken the battery by cooling it. Check it out they say store your battery cold but not below 32deg. The chemistry of a battery makes more power when warm than cold that's why they are rated in cold cranking amps at 0deg and cranking amps at 32deg and marine cranking amps at 80deg. If say a mechanic in 1950 took the battery out of a car that won't start in the winter and left the weak battery on the cold floor chances are it would weaken more if not freeze. Anyway this is where the myth came from, its not the cement its the extreme cold that weakens a battery. Link to comment Share on other sites More sharing options...
Billy Bob Posted May 4, 2010 Report Share Posted May 4, 2010 I no longer remove my two boat batteries for winter storage but rather just keep my on-board charger plugged in to maintain them. However, if I did remove them and put them in my basement as I use to I would still put them on a wood board as I was taught even in college (Alfred Tech)...what's so hard about putting a battery on top of a board...

Man, how stories are twisted, many years ago battery cases were made of a porous material, not leaky but just porous enough that the acid could react with the cement, Cement is a base substance (alkaline) and when it reacted with battery acid it neutralized the fluid in the battery, therefore no more electrical reaction or "the battery died" because it was sitting on cement.

Fisherman, I'm with you on this one. It is really funny how information gets all twisted about as it passes from one person to another! Link to comment Share on other sites More sharing options...
Fish4Eyes Posted May 4, 2010 Report Share Posted May 4, 2010 When I bought my Interstate deep cycle the guy at the marina said that Interstate specifically told them to leave the batteries in the boats for outdoor winter storage. I did so, and never had an issue. This year will be my 3rd year with the battery. Link to comment Share on other sites More sharing options...
POLLIWOGG Posted May 4, 2010 Report Share Posted May 4, 2010 OK so the battery acid leaks out ,gets neutralized, somehow climbs back into the battery and neutralized the rest of the acid, sounds good to me. Link to comment Share on other sites More sharing options...
solopaddler Posted May 4, 2010 Report Share Posted May 4, 2010 I have some mountain property for sale in Florida, real cheap. Now you know which battery guy to stay away from, he's full of it. Just to clarify you're saying extreme cold won't hurt a battery when exposed to it for an extended period of time? Link to comment Share on other sites More sharing options...
Terry Posted May 4, 2010 Report Share Posted May 4, 2010 OK so the battery acid leaks out ,gets neutralized, somehow climbs back into the battery and neutralized the rest of the acid, sounds good to me. well the cement floors reacted with the battery casing be absorbed and over time would work it's way to the acid and neutralize it Link to comment Share on other sites More sharing options...
lookinforwalleye Posted May 4, 2010 Report Share Posted May 4, 2010 Just to clarify you're saying extreme cold won't hurt a battery when exposed to it for an extended period of time? Don`t know what your definition of extreme cold is but I have always stored my batteries in a unheated garage over the winter without incident. Just keep the battery charged.

Fisherman Posted May 4, 2010 Report Share Posted May 4, 2010 Just to clarify you're saying extreme cold won't hurt a battery when exposed to it for an extended period of time? When a battery is fully charged, (specific gravity of 1.260 or about 12.7 volts measured after charging and waiting a day, that battery will not freeze until you hit about -60), if it gets that cold where you are, I'd be more worried about long underwear and having other parts get frosted. I store mine on the cement floor in the garage, although it's heated to about +5C, the floor is pretty close to 0C. Link to comment Share on other sites More sharing options...

Rattletrap2 Posted May 4, 2010 Report Share Posted May 4, 2010 If freezing was an issue, we would have to bring our car batteries inside every night! As long as they are charged, batteries will be fine in sub zero weather. Link to comment Share on other sites More sharing options...

Okay let's say for the sake of argument you're storing two batteries, one inside, the other outside. Both aren't topped up. Will both survive?
