[RE-wrenches] Frozen T-105s

[Dan Fink]

Yes, you MUST thaw them completely first before trying anything, Sorry, I
thought that went without saying.
Good point on the cost-benefit analysis, but when the cost of
transportation of a new battery bank and removal of the old exceeds the
retail price by 2 - 10x, it's worth trying. If the client can just drive an
hour to Sam's Club and buy another set, a $600 service call is likely not
worth it. Just direct them to the Battery University website and wash your
hands of it.
