So I bought an Avaya UPS for my server the other day, it's an older unit that I bought off ebay. Problem I am having is it seems to not charge the battery, if the power goes out it just turns off after a second, also it fans come on and then go off constantly. Dont know what else to do with it and am about ready to return it

 

It's an Avaya 9125 1500VA

Sounds like the battery in it is dead. Replace the battery.

In my experience, those indicators are hit-or-miss. Mostly miss.

Well, take the battery out and test it manually. It's pretty easy to confirm if it's dead or not.

Open it up, check fuses, measure voltage on the battery. check mechanical relays (if any... relays may be stuck and not connect battery to the inverter while the circuit that reads battery voltage can still measure)

 

The circuit that measures the battery voltage may be faulty, led may be faulty (extremely rare but you never know),

I opened it up, the fuses seem fine, how would I check the battery? I have a multimeter just not sure what it should be reading

Set your multimeter on DC voltage, if it has manual ranging set it on 20v or higher position, place the probes on the terminals of the battery... You have a plus and minus on the battery... your multimeter will show the voltage.

A good battery should show a voltage between 10.8v (discharged) and around 13-14v when floating or full charged.
