Not a fully controlled one.  However, I store most of my lead batteries on 
the garage floor.  I have a LOT of them -- flooded, gel, and AGM.  I have 
NEVER had significant self-discharge problems with any.

I think the key is keeping the tops clean.  Because the floor can be a 
heat 
sink, it may cause the batteries to be cooler than ambient.  This might in 
some conditions cause condensation on the battery tops.  If they're clean 
that has no real effect; but with dirt and electrolyte spray left there, 
it 
might.

As I say, I've never had any excessive self-discharge problems with 
batteries stored on the garage floor.  Or cellar floor, for that matter.

I can't see how this would have any effect unless the battery were somehow 
connected to a grounded circuit.  Am I missing something here?
