Fits perfectly inside the CyberPower UPS battery compartment and everything is identical to the original battery pack that came with the UPS. but at least 50% less expensive. I have had it since I purchased it about a year ago and it has failed me yet and has been working like the original battery package.

- Great packaging, fast delivery.

R&R the original with the replacement with no problems.

Great seller and fast shipping. This replacement battery is a legit APC replacement part.



It works. It came fully charged (APC's literature made it seem like it would have to be charged for 6-8 hours before running self-test.)

An exact replacement for my 6 year old APX XS-1000. The original battery died some time ago (~5 years) and the unit continued to function just fine. Only just recently did I noticed that the battery did not work after an ice storm. After replacing it with this battery, the unit was able to switch to backup power successfully. Didn't even have to shut the unit down, just swapped it out.

Delivered right on time. Easy to remove old battery, this one slides right in. Comes with a slip to indicate that all pre-shipping tests were passed. Looking forward to a few years of trouble-free UPS-ing. Easy, free path to ship the old battery for recycling.


It's a big battery. A big, HEAVY battery. 75 pounds. I tipped the UPS guy for having to lug it from his truck. Is it being heavy a pro or con? It's not really a pro, but I don't know how you'd avoid it, so it's not really a con. Why can't they make batteries out of Aerogel? Have only had it a few weeks. Have gone through one power outage and it performed as advertised. I guess I was drawing less current than I thought, because the runtime looks to be longer than I thought (based on how fast the battery was draining).

Fit right into the UPS system without having to power the network servers down. Hot swappable.
