I have the 1350PFCLCD (which has 2 batteries) and the output is:

battery.voltage: 16.0
battery.voltage.nominal: 24

The USB info is:

Bus 002 Device 007: ID 0764:0501 Cyber Power System, Inc. CP1500 AVR UPS

A real Lead Acid battery has a voltage of 13.8 not 12, so it shouldn't be 
reporting 24 volts for the reading, but 16 volts is certainly wrong.

    0.022302     Path: UPS.PowerSummary.ConfigVoltage, Type: Feature, ReportID: 0x09, Offset: 0, Size: 8, Value: 24.000000
    0.022332     Path: UPS.PowerSummary.Voltage, Type: Feature, ReportID: 0x0a, Offset: 0, Size: 8, Value: 24.000000

The UPS reports 24 volts so I would just leave it as reported and not 
scale it.
