Answer / dheeraj

AH stnads for Amp hour capacity, Back up depends on the AH
capacity of the Battery.
For Examlpe if you have 100 AH batery of 2 volt, it means
at 2 volt and 1 amp load can give you 100 Hrs backup OR at
2 volt for 2 amps load the back up time will be reduced to
half i.e. for 50 Hrs only. simply You calculate A x H.

Answer / k.prakashchandra

The KVA of UPS has nothing to do with back up time . The
back up time is = stored energy in watt hour/load in watt.In
this case Back up time = 17 x 8 x 12 (voltage of each
battery)/ 600 =2.72 hour

Answer / krish

back up depending on you'r load so you have 17ah battery.
so u can put on the full load 600w taken 2.6A so this
is given backup for 6oow 6.5hr
