PSUBS-for-DUMMIES time.

The whole "oil and battery" thing just ain't sinking into this skull
of mine.  Are we talking about regular old 12 volt lead-acid car
batteries?  If so, are they the kind with caps or the
"maintenance-free" type?  If they have caps, are we talking about
taking the caps off and putting oil inside the cells? Or are talking
about filling the pod that contains the batteries with oil, therefore
surrounding them with a protective non-compressible material?  Are
there ways to protect a "maintenance-free" battery?

What about off-gassing?  I understand that batteries do it, but how
does that create a vacuum in a containment pod?
