Hi! I'm varun, I have one emerson ups connected with three external batteries of 12V each, when power supply is not available it get off & also continuously beeping when it is on, What should I do to get rid of this problem?

Replace the batteries.

No way to charge the batteries?

Utility Battery Chargers, Stationary Float Battery Chargers - Eagle Eye

If you have a volt ohm meter to test the batteries individually you might find that only one is bad and is causing all three to fail. Sort of like putting 2 good batteries and one dead one in a three battery flashlight and it will not light.

Thanks I will try that! Appreciate the help.
