I am trying to find out the UPS capacity in amp-hours for my HP UPS system. I've already done some calculations based on the UPS information from the HP Power Manager software.
Bellow are my calculations but somehow I doubt them and I think I am making a mistake somewhere:
Output Power: 1160W
Output Voltage: 235V
Run time remaining: 12min - Converted to hours that is 0.2h
First I am converting the W to A:
1160W / 235V = 4.936A
Now to find the amp-hours for 12min that are specified in the run time remaining:
4.936A * 0.2h = 0.987Ah
Can someone more experienced in batteries, current and UPS Systems tell me if my calculations are correct?
I am not sure that I have taken the correct values into consideration since my calculations are based upon the output values from the UPS.
Also as a side note I must tell you that I am not very fond of current and all that stuff and I have only basic knowledge about amps, volts and watts from college.
