I second that. I've seen UPSes dying instantly when switching the load to a
dead but apparently kicking battery.

I've a better idea than that. Has anyone a script that looks at upsc 
output say every 15 seconds and finding an ONBAT in that timestamps it 
and writes the battery voltage to a log, not on the u-sd but to an SDD 
for later checking of the battery's performance? I have 380 G's of
SSD's
on that pi, and everything in the high traffic category but /tmp has 
been moved to the SSD's. The u-sd gets about 50 megs a day of write 
traffic, and the wear leveling has now handled that for a year, its a 
64G card with about 12G used so it has plenty of
playroom
