Works great. Fit my APC XS 1500, comes with a replacement wire bridge, and also double sided tape to stick the batteries together.The only issue I can see is after letting the batteries charge with no load for 2 hours, it comes up as only a 1 minute run time even with a really low wattage draw of 122 watts, and 14% load. I attached pictures for reference.

. Lasted about 6 years, no complaints at all, saved a ton of money not buying another power supply.

I put this in my UPS and it works great! The original had the two batteries glued together. The replacements were separate so it took a little effort to get them into the UPS. Maybe double sided sticky tape would have helped unitize them and make it easier to put into the UPS body.

not even use every dayi use this as a backup for internet and low wattage items.when they were working i got 1-2 hours of backup power from them.yesterday the power went out and i nosiest the UPS did not turn on. DEAD.not even a full 2 yearsat least they did not break the UPS

It works as advertised; but, I would advise getting the pre-assembled two battery pack. My time is worth more than the money I saved.

the batteries came in great condition, but I kept having to play with the center part (I had to reuse from old battery) I taped them together, they would work but would not apply enough pressure to the pins up top, I eventually got them working by finding the exact spot they needed to be to push the pack connector in at the correct length without the batteries sitting to low and keeping you from putting the cover back on, superglued each battery to the plastic pairing piece I removed from the old pack and they worked, but I wont ever be able to reuse that vital part again and next go around will have to find the exact APC replacement pack

Batteries work just fine and have been for several months now. I must note that will need the harness from your old battery set. Carefully lift those old batteries off that bracket and place the new batteries in the same orientation. Adding a piece of wide scotch tape to hold those batteries in place will help when you slide the new batteries back into your UPS.

They worked fine to get my APC back up and performing as it should. Time will tell how good they are. My last set had a battery go bad within 2 years so I tried this set.
