Which UPS?

[drhowarddrfine]

I have the same Tripp-Lite "Internet Office UPS" that I've had for the last umpteen years. I think I replaced the battery once but not sure. It still works as of a couple of weeks ago when a car hit a power pole down the street and took everything out. Lasted about five minute or more on battery while running my super duper workstation.

To avoid the headache of replacing batteries, I simply buy a new UPS once every 5-6 years.
I still continue to buy Eaton UPS...I recently bought this one - https://www.eaton.com/gb/en-gb/skuPage.9SX1000I.html for my second server (dual socket Xeon 5220 Gold). We often have power outages. This is especially critical when you backup virtual machines (they are large, with 300 GB disk images, I do not use RAID). My online UPS instantly switches to batteries, and the system can work on batteries for ~ 20 minutes.

No, not a joke. The cost of batteries is comparable to the cost of the entire UPS (at least in my country).

Edit: in the US the cost of batteries is ~$90 (https://www.upsbatterycenter.com/eaton-9sx-1000va-9sx1000i-compatible-battery-set), on eBay - $260 (,https://www.ebay.com/itm/166901559157), in Russia - $450, and a new UPS here is ~$500.

The chirping happens during a self test. Lasts about a min but it will get your attention. It is only one UPS of a bunch but it is not lying.
I am sure they are beat. Why one bach wore out faster will be good to see.
I used some of those generic "Mighty Mule" SLA just for comparison to good ones like Enersys.

I could probably strech them some but we have a degrading electrical system here. Any big wind event and you are going to see outage issues however brief.
Aging infra. Refusal to bury old runs. Lots of trees.

If you buy the usually hideously overpriced replacement packs (including some mounting sled, cabling etc...) from the UPS vendor, then yes. But there's plenty companies that offer replacement battery sets that contain only the batteries or depending on the UPS also some cabling and some mounting material (but not the whole sled). Those are usually 1/2 the price or less than what the UPS vendor asks, even with high quality batteries e.g. from yuasa or CSB (which very likely are the OEM for the UPS vendor...).
Sure, replacing the batteries individually is a bit more work than just replacing the whole battery sled, but you easily save 50%+...

We buy our batteries from a local battery supplier and UPS reseller/repair shop, that is just a few minutes away - this way, we can have replacement batteries (or even a new or refurbished UPS) in less than half an hour if something goes completely sideways...
