Grabbed a refurbished UPS from a surplus sale and it worked too well
I found this old APC UPS at a county surplus auction for like $15. Figured it would be junk but I needed something for my home lab setup. Plugged it in, ran the self test, everything looked fine. Then last week a storm hit and the power flickered like 4 times in 30 seconds. That little UPS kicked in and kept my server running no problem. But then the power came back and it just kept beeping nonstop for 20 minutes until I unplugged everything. Turns out the battery was so old it couldn't handle the recharge cycle and started swelling. Lesson learned, next time I'm just buying a new battery upfront before even using one of these things. Anyone else run into weird issues with surplus UPS gear?
