battery charge percentage for your UPS. This seems to be related to the fact that the nominal values (aka: UPS ratings) are also missing, which makes this an unfixable issue on the driver's side. You can, however, pass the battvolts parameter to the driver (in ups.conf) and the calculation will be done based on those values. For example "battvolts = 20:27" means "battery.voltage" is 27V when the UPS is full, and 20V when the UPS is empty. You can also check the manpage. -- Carlos Rodrigues
