The procedure did not work with the battery totally unplugged. Perhaps it works with a low - but not 0V - battery. I will see if I can arrange one. ... > Thanks for the input - that sounds (correct me if I am wrong) as if one > were to connect the free ends (say with alligator clips attached?) of a > cable of the description you gave above to a fully charged 12 V 7.2 AHr > battery (i.e., the same type as the one in the unit itself), and the > barrel end of that cable to the BBU auxiliary port provided, one could > be good to go?

A small gel cell battery has a different impedance and capacitance than a power supply, or a car battery, for that matter. Does the auxiliary device have a separate charger, or is it charged by the main unit?
