Does any UPS mfg offer ampere-hour ratings? I would expect to see a
table representing operating time at 1) max current rating, 2) current
at max time, and 3) optimal time-current. The rating should specify the
output voltage range (fresh charge and final) of the measurements. Deep
discharge battery banks used in emergency services, such as Ham radio,
use such a rating system.
The UPS's I've looked at don't even publish the battery specs. (can I
substitute my 60ah gel cells?)
In this day and age, I guess that's too straight-forward and honest.
