Ernest,

Also, in my experience with telco batteries, they are never placed on a cold
concrete floor. They have always been in some kind of rack, maybe only 4 or
5 inches off the floor, but always off it. I think that has been very
effective in keeping the battery at room temp.

Gang,

I think here is the key. My house has a concrete floor right below that
carpet. Now, in Houston I don't especially worry about things like freeze
line but if your floor gets significantly colder than room ambient temp you
should probably make yourself a rack to keep them elevated. If you put your
batteries in a garage, maybe even an enclosure (properly vented so they don't
blow up on you!).

The specific gravity layering effect starts to explain a lot. Of course, if
you can explain all the things that happen in Ni-Cads, we'll all become very
reverent while you speak.
