I own some Ablerex MARS 3000 (MS3000RT) UPS.
Following the thread here :
I would have the following issues :
1. The battery charge displayed seems wrong : It always shows 100.0 - even
when the battery is disconnected for replacement.
2. Battery voltage 2.29 is also static ...and wrong. The initial assumption
of being the voltage per unit seems wrong : the ups uses  8 x 12V batteries.
8*12 = 96V , same as  battery.voltage.nominal: which is correct.
The initial poster seems to have more credible results at least regarding
the battery.charge: variable, however in my case the value is wrong.

System params :

#upsc Ablerex2
battery.charge: 100.0
battery.voltage: 2.29
battery.voltage.nominal: 96.0
driver.name: megatec
driver.parameter.pollinterval: 2
driver.parameter.port: /dev/ttyUSB0
driver.version: 2.2.0-
driver.version.internal: 1.5.4
input.frequency: 50.0
input.voltage: 227.1
input.voltage.fault: 190.0
input.voltage.maximum: 230.6
input.voltage.minimum: 216.5
output.voltage: 221.3
output.voltage.nominal: 220.0
ups.beeper.status: disabled
ups.delay.shutdown: 0
ups.delay.start: 2
ups.load: 95.0
ups.mfr: Ablerex
ups.model: MS3000RT MS02035C
ups.serial: unknown
ups.status: OL
ups.temperature: 55.8

Any ideea about the cause of the anomalies ?

Thank you in advance.
