Have a few UPS that used 12 volt 7 ah batteries, when it came time to replace the batteries I used 12 volt 12 ah battery. The bigger battery does not fit
in the original UPS box, just have the batteries next to the UPS. This defiantly gives longer stand by time. Have been tempted to try the same thing using
a car or even larger truck battery. This might require a separate trickle charger to keep the big battery at full charge. Also have to keep in mind with a
car battery there might be out gassing from the battery that would cause trouble in a confined area.
