keymast, if you can open your 825avr unit take picture before disconnecting battery. then find local car/truck battery retailer locally that also deals with SLA batteries for alarm systems and emergency lighting systems. They should be able to source an exact replacement for you. Or else search the web using the search term "sla batteries" or "sealed lead-acid batteries" . You will get plenty of hits on web. 12fixlouie

It may not be dead yet. Does it supply output? You have not mentioned. It would be considered dead if it does not give any output. Is the battery fine? If the battery is fine and there is no output then it may be dead.
So, check the battery for any sign of life.
Check the output.
Check output with it plugged into mains.
If all are negative then it is dead.

Atypically if this is an older unit what you have is an issue with the battery. It will no longer hold a charge.

You will nee d to go to the vendor site and look for a replacement battery.

In some cases it may be less headache and cost just to buy a new one.

It would appear that you need to replace the battery on this unit.
You could get a new battery from a local battery specialty store like Batteries Plus or Interstate Battery, or online at www.replacementupsbattery.com. A new battery would be about $30. If you took your old battery there, they could recycle your old one, as well as match it up with the correct one you would need (BP9-12 battery).
