[Request for Recommendations] 1U-4U Uninterruptible Power Supplies (lemmy.inbutts.lol)

I recently stated out loud that my homelab was stable, and now my UPS is posting less than 30 minutes of estimated normal load. What's everyone using as a UPS?

I've been rocking the aptly-named CyberPower OR1500LCDRT2U for the past few years. Should I just replace the cells or upgrade the whole unit?

Dang, that thing is the bees knees!

Would make more sense to replace just the batteries rather than the whole unit IMO. Looks like it takes standard 12v 7Ah sealed lead acid batteries, so should be doable for under $120 (if you buy them individually and use the existing battery harness)

I have three other UPSes, but none of them are as good as yours lol:

APC SUA1500RM2U - was a great online rackmount unit, stopped using this a few years back because of its tendency to overcharge batteries without a charge controller ADC calibration mod. It wrecked my last battery pack bad 😭 plan to convert it to LiFePo4 and put it back into service 🤞
Zigor Ebro - cheap and cheerful line-interactive UPS for the modem, network switch and CCTV cameras. Switchover time is pretty much instantaneous, worth every cent paid and has kept my network up through many outages
Cyberpower UT650 - A temporary offline UPS to hold the server gear specifically until I get the APC back in service. Honestly not worth the cheap price, the switchover delay is long enough to shut off anything that's not a server PSU with massive bulk capacitors
