After less than a week, the UPS unit started "chirping" intermittently and then became more frequent to the point where the UPS indicated that the battery had failed

UPS working like new again, with plenty of reserve operating time for my system.

revived the old UPS.

Two bad batteries in a rwo may indicate only 2 or 3 things - this is either bad product or it is not compatible with my device (which I checked before purchase and it should be compatible) or my UPS has a defect

Restored UPS battery life to same as when knew.

Installed new battery and the UPS is like new again.

My UPS is happy with the new battery, so am I, was tired of the beeping battery warning.

Be sure you have correct UPS & battery model match-up; the APC web site has charts for this if needed.

We just had the first brownout of the season and the UPS started alarming

They do cost more but still not as much as a new UPS, and certainly nothing near the cost to replace my damaged wood laminate floor section (now all my UPS's sit upon a 12 x 12 square of tile to protect the floors, NO thanks to Mighty Max!).

With this battery, it had the APC sticker on it and when installed, the UPS gave no protests, warnings, beeps or anything else.

My UPS was making beeping noise with a blinking battery out of order signal.

My UPS still works without any problems after I've bought it.

Battery has been installed in UPS for about 4 weeks, UPS works great.

On December 11, 2017, the UPS began complaining again that the battery was bad and needed replacement

Fit my UPS and works like original

The UPS was sporadically giving audible alarms even though power to it was fine, so the battery was the most likely culprit

This allowed me to restore the UPS to service, protecting my equipment in this lightning- prone area.

My UPS wasn't working correctly.

Arrived quickly and did the job of getting my UPS to stop alarming.

Rejuvenated my old UPS

Rather than replace the entire UPS when it died as we usually do, we bought this replacement battery

The replacement battery pack was a perfect match and my UPS is working fine again.

Included a link for a free UPS return label to recycle the old battery.

Amazon (or their external vendor) had a better price for this battery than some other on-line vendors, and that helped me decide to try the battery vice a new UPS.

my UPS lost a volt and i could not get it back up since this was a sealed battery.

It's still working but my UPS is making noise now and lagging when starting

And even then 450VA UPS outperformed the 750VA UPS that this horrible battery went in.

Am unable to return, so I'm just stuck with the thing and will need to buy a new UPS as well.

The previous UPS by APC unit worked for 5 years.

The UPS worked fine
