One thing though, I'm not sure if you are damaging your batteries by letting them run down by 1/4. If the batteries was charged to 13 volts before starting and you let them run down to 9 volts, that may not be good. Others can respond.
Larry N. said:Perhaps I misread this, Rene, but I have the impression the OP is reading the 4 (or maybe 5)-position readout for the battery, not the voltage, so I'd read that as taking it down by roughly 25% of the charge, not the voltage. Obviously, if it were voltage, that would be pretty much dead, and the CPAP wouldn't still be running at the end.
