"remaining battery charge is 101%, battery is currently charging" 01/21/2014
This review is from: APC BE750G Back-UPS 750VA 10-outlet Uninterruptible Power Supply (UPS)
bought it when it was on sale which was a great value. some outlets are spaced apart which is great for wall warts. this is my second of this unit.
half the time i check with power chute, it says remaining battery charge is 101% and battery is currently charging. according to the APC forums, this is a bug in the firmware. i was told units produced next month won't have the bug. also, the firmware is not user upgradable so there is nothing you can really do about it. from what i heard, this firmware bug does not effect the performance of the unit, it is just cosmetic. -2 for that.
when checking the output voltage of the unit while on battery power, you may get a reading around 80 volts if you don't use a true RMS volt meter because the output waveform is step approximated to sine wave and cheap multimeters don't read that waveform properly. the power supply on your PC may produce harmonics (buzzing sound) when powered on battery power because of the waveform.
