I have two "maintenance free" sealed batteries. Yesterday when I
checked the battery trays where the batteries are secured in place, I
found that both battery trays are quite wet (like 1/16" deep). This is
odd. The batteries are inside a compartment that is protected from
elements, and the rest of the compartment is completely dry -- only the
battery trays are wet. I am sure the water is not from the air because
the air in early winter is relatively dry.

I am not sure if both batteries are leaking or not. I cannot tell. I
have a feeling that I should not expect _both_ batteries leak at the
same time. Anyway, I have already dried the battery trays. I will
check this next weekend to see if they will become wet again.
Meanwhile, I would like to know if there is any "known" reason that can
cause a battery tray becomes wet like mine.

Thanks.
