I posted this last April. Forgot to run battery test on a regular basis and found out that the UPS battery was dead. One test and everything died. Fortunately Win 7 is good at recovery. Since then I use Google's calendar to remind me once a month to test the UPS. Tonight, over north Wales we're having a thunder storm and the UPS is working well. Learnt my lesson.
I have 12 UPSs to check every three months, I can do most of them at a flick of the three phase breaker. I turn all the PCs on and then leave the birdies to cheep, the PCs should last 15 minutes and the phone system an hour. If not I get my new batteries from here.
