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.


So you can find the model’s battery here, and then google that and batteries plus. I have an 850M model which uses the rbc17 model. I’ve highlighted that on the apc site on this photo:
Thank you! This is the part I was missing, and felt like I was blindly picking batteries. This feels much safer
