Michal,

I ran across this Debian bug today:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=707223

It's a bit of a corner case, and it's for NUT 2.6.4 (apcsmart driver v3.04), 
but I was wondering if it was still applicable for the latest code?

It might be, I don't recall changing much in context of those commands - and the code never relied on registers.


"nut reports 100% battery charge after unplugging the battery on a Smart-UPS 
2200 RM (SUA2200RMI2U) using apcsmart.
Powerchute correctly reports the missing battery. The front panel displays 0% 
charge and change battery is flashing.

The Smart Protocol commands B (Battery voltage) and f (Battery level) report 
false values of 55.35V and 100%.
The missing battery might be indicated by register values:

Register0: 00
Register1: 20
Register2: 00

Register1 indicates: Command sent to stop bypass with no battery connected - 
UPS still in bypass

All register values are 00 on an identical UPS with a connected battery."


I'll try looking into it.
