[Apcupsd-users] BX950MI shutdown too early / MINTIMEL and MBATTCHG are not respected.

[Benny K <Be...@gm...>]

Hi there,
 
I bought a new APC Back-UPS BX950MI.
Works fine so far, but the shutdown of my computer seems to be too early after power failure (approx. 5minutes after powerfailure) ..  

What I noticed while in power-failure:
- After 5minutes the Charge is at 91.0 Percent and Time Left "54.4 Minutes"... looks fine for me
- STATUS changed from ONBATT to ONBATT LOWBATT and then the system shuts down..
I wonder why MINTIMEL:5 Minutes and MBATTCHG:10 Percent are not respected. Is the shutdown initiated too early, because of the "ONBATT LOWBATT" after 5 minutes?
Is there a way to adjust the threshhold for "ONBATT LOWBATT"?
Please see below for timeline, apcupsd.conf, apcaccess-output, apctest-output
By the way: I installaed apcupsd-version: 3.14.14-3.1
Thanks and Best Regards
Benjamin
