I thought I was smart because I invested in UPS backup from the start.
Then 5 years later there was a power outage and the UPS lasted for about 10 seconds before the batteries failed. That's how I learned about UPS battery maintenance schedules and the importance of testing.
I have a calendar alert to test the UPS. I groan whenever it comes up because I know there's a chance I'm going to discover the batteries won't hold up under load any more, which means I not only have to deal with the server losing power but I have to do the next round of guessing which replacement batteries are coming from a good brand this time. Using the same vendor doesn't even guarantee you're going to get the same quality when you only buy every several years.
Backup generators have their own maintenance schedule.
I think the future situation should be better with lithium chemistry UPS, but every time I look the available options are either exorbitantly expensive or they're cobbled together from parts in a way that kind of works but has a lot of limitations and up-front work.
My APC UPS self-tested and monitored battery status automatically. Then started to endlessly beep when it noticed the battery needed replacing (could be muted though). Eventually, I stopped using UPS since I rarely needed it and it was just another thing to keep and maintain.
