I was digging around in the van today getting ready for a trip next
weekend, and I noticed that my aux battery had a bunch of moisture on the
outside of it's case.  It's a yellow Optima deeeeep cycle number.

Is that just condensation?  Should I be worried about this?

Note: we had a real sunny day here in Seattle for the first time in a
while, so it got pretty warm today.

Also pending a battery box for it, what are the ramifications to driving
around with it disconnected?

Thanks in advance.
