[RE-wrenches] Frozen T-105s

[RE Ellison]

Regarding thawing frozen batteries be real careful they can take an incredibly long time to thaw .

Lotta lead there to get up to temperature it is not in a hurry

Just my .02 !

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.

When I inspected the electrolyte levels I discovered it was frozen in some cells, the voltage of the 48 volt pack was ~8 volts, I didn't check individual batteries due to these facts...I'd seen "enough".  Recently temps have been in the high teens, though we are back up to low 30's.
