APC BR1600SI discharges when switched off
I've bought brand new APC BR1600SI UPS. I charged it to 99% and turned off at night. Next morning when I turn on UPS, Power Chute Personal Edition shows 85% battery charge remaining. All the time UPS was connected to AC power.
The question is is the UPS broken or doesn't it charge battery when switched off?
