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.

But do not use the "motor" ones for a UPS.

If their size and capacity is equal or similar, why not?

You should use the AGM variant (if lead batteries at all)
