I have 2 UPS’ that have expired batteries. The manufacturers want crazy amounts of money to replace them, and a friend recommended I look online to see if I can get them elsewhere. However, the sites all seem so sketchy. Have any of you had good luck with third party battery sites? Obviously a bit nervous about safety.
There are multiple tiers of batteries, I got the $50 one I linked but the first hit was $120 on their site.
