===================
Robert,

If you don't need to run them, just let them sit. It's worse to run them
a short while during cold weather because they generate LOTS of residues
/ acids / moisture that just end up in the oil, but don't get burned off
because you're not warming it up or driving anywhere.

If you have access to a trickle charger put that on overnight before you
do get them going again. Make sure the batteries are not frozen (which
happens if it discharges due to something left on, or even car alarms
over _long_ periods. Don't charge a frozen battery. You can even take
the batteies into the house if we're talking about months of no usage,
but you'll still have to put a bit of charge in from time to time.
