The sealed batteries in these last about 6 years. You are correct in thinking that you may need a new one. Very easy to install. Here's a supplier of these: http://www.batteryinternational.com/dynex-te685avr-ups-battery-ups-batteries-f1.html

Testimonial: "There is no way to check the water in the batteries as thry are sealed. I found out that after a load is applied it goes on battery for a few seconds "
I have found your user manual here: http://www.apcmedia.com/salestools/KBOK-76HP9K_R0_EN.pdf
It looks like a re-badged APC unit, so the problem is either the battery is dead (probaby likely no matter what) and unable to support the load, or an overload condition is detected.
it is also possible the unit has gone faulty, but without more information I can not be sure.
If the manual does not help or you are still not sure, give me some more information before rating and I will continue to try to help.
