Although these batteries cost about half the price and have the same rating on paper as the original batteries, their in-use capacity is not adequate.

I have a 700VA UPS system, which is loaded to about 40% capacity, along with monitoring software. The original batteries would keep my entire system up for about 15-20 minutes during a power loss. I also have a small LED desk lamp plugged in. When the power fails, I immediately shut down the PC and can use the LED lamp for about 12 hours to supply light if needed. These replacement batteries, when fully charged, can only keep the whole system up for about 1-2 minutes and my LED lamp will only run for a little over 1 hour. You get what you pay for I guess.

Owning several UPS's I'm going to say spend the extra $ and get the real thing. These worked fine for a while, but 1.5 years later these batteries nearly burned down my house. Fortunately the APC shut itself down from the heat - it was so hot I could hardly pick it up. When I opened it up, the batteries were warped, leaking, and hissing. I've gone 4 years with APC batteries, and the worst that happens is they don't hold up in a power failure or the agent alerts you to replace them (in other words the UPS is fine).

Only positive I have is they worked fine during power outages before they self destructed.
