217.0. "Battery storage on concrete floors" by BTO::JPETERS (John Peters, DTN 266-4391) Mon Dec 12 1988 08:51

    This is the closest I have ever seen to a rational reason not to
    store your battery on a concrete floor...

Note 481.12  What kills a storage battery stored on the basement floor  12 of 15

--------------------------------------------------------------------------------

    The reason a battery shouldn't be kept on a cement floor is because
    of the temperature differential between the floor and the surrounding
    air. The voltage of a battery changes with temperature. When a battery
    sits on a cold floor, the bottom is colder than the top. This causes
    the top to try to maintain a higher voltage than the bottom and
    the resulting current flow will discharge the battery. A similar
    problem may arise when batteries are connected in parallel, although
    GM got away with it on their diesel cars.
    
    The recommended way to store batteries is off the floor with a
    cardboard box placed over them upside down. The insulation helps
    to minimize the temperature fluctuations.

	re: .0 Thanks John.... I guess I never really gave much thought about whether there was another reason for the cardboard box other than just packaging.. BTW: A battery sitting on the cement floor will certainly die in much less time than the entire winter..... Rick

	Another good reason for a box over the battery is to protect whatever MIGHT get stacked on top of it from getting vaporized if it happens to short out the terminals. Like, lotsa stored energy in that little plastic box of acid and lead. R {whose battery is still in the boat}

	I agree with note -.1 Ever seen what happens when a wrnch is dropped across battery terminals? A few years ago, I got a nice big hole in my hood that way. Never did find the wrench. Tally-ho, Ray
217.4	What about storing below sea level.	PILOU::ZEE	Multi-Processing pure Schizophrenia	`Wed Dec 14 1988 04:11`	10
	I have a almost brand new battery with went a while ago just a little bit below sea level, it got filled up with salt water and complete discharged. I tried to charge it again but am not sure about the results. Does anybody has a clu , throw it away straight away or can I fixed it ? Harrie from the south of France..
217.5	Can't stor'em there	GENRAL::NORVELL		`Wed Dec 14 1988 14:07`	16
	You can have them checked to see if they are any good, but like the two I tried to store below, sea level, the only thing I could do is drag out the bucks and buy new ones. The old one's make great paper weights, not a total loss. Mike
217.6	stay well upwind!	HAL900::STEWART		`Tue Dec 27 1988 09:16`	8
	Getting salt water in a battery is a bad idea. First, the sodium chloride mixing with the sulphuric acid will produce Chlorine gas, extremely extremely extremely poisonous. The other byproduct would be sodium sulphate, which is useless for producing electricity. Even if you could wash the sodium sulphate out, I suspect that the lead compounds that the battery requires for operation would have been destroyed also. I would get a new one.
