This is part UPS and part nut question.
I had a (intentional) power outage. The UPS/nut properly shut the system down
when battery was down to 20%.
It ran for only 18 minutes rather than the expected 40 (see later).
After it charged to 37% I removed power from the UPS. After 4-5 minutes the
system shut down.
However, when I restored power to the UPS the machine powered up immediately
(no delay). I though it was supposed
to wait for a higher charge?
Nevertheless, the UPS reported a charge of 58% when the machine restarted, I
expected about 20%. Free energy?
Q1) Does this last exercise indicate a bad battery that woke up on the second
restart?
Or a failed UPS?
The UPS is a Eaton 5E1500i. It is only 6m old and within the warranty
period.
Q2) What is the parameter I need to set on the UPS for a minimum charge before
restarting power?
