Re: UPS batteries dont last forever
It's always the same thinking by beancounters. It's working, right, so why do regular maintenance on the batteries.
I have 6 UPS across my site, carrying 46 batteries, rated 120Ah. I requested new batteries $Diety knows how many times, until one UPS started going down within a few minutes of operation, before the Diesel gen would kick in, and they got their wake-up call. Minimum age of batteries was 5 years by that time.
We do regular tests though. But not by choice. Power fails at least once a month because of lightning strikes at the local substation, or just because of shoddy infrastructure problems.
Fun extra, the diesel gen doesn't supply power to drive the building airconditioning, so humidity shoots up pretty fast. Don't turn machines back on (after controlled shutdown) right after a power restore. Condensation is a killer...
