Re: UPS batteries dont last forever
My lot did it on a weekend because while there was a UPS, it was for the servers. everything else in the building got a few seconds of dead power while the generator spun up.
On the plus side, they weren't doing anything important most weekends so if it didn't come up, we could fix it on Monday no issue, and it never failed. So much no issue that Facilities stopped telling IT when the tests were happening.
And then, one day, the UPS exploded.
