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.


I trust Batteries Plus, stupid question though, what do I search for? This is new to me, given that I have my APC model, how do I derive what I need from Batteries Plus?
I had no issues walking in with my battery. They pulled a replacement from the shelf within 15 seconds.
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
There are multiple tiers of batteries, I got the $50 one I linked but the first hit was $120 on their site.
