The best that I can determine from the Hawker manual is 15-20 minutes
maximum at this discharge rate. When the battery reaches critical
discharge, the output voltage will start to fall rapidly, but until that
time, it will be on a fairly gentle glide slope of a few millivolts per
minute decline versus 100mV per minute as it takes the end of discharge
> 1.5 - 1.6 amps
