[SOLVED] APC Back-ups 550 - Beeping 4 times every 30 seconds

[PsychoPsyops]

Replaced the battery, power goes to only surge side when LED is off.
When power button is pressed and green LED is on, power goes to the battery side as well, but beeps 4 times every 30 seconds.
I had already tried power-cycling the unit as well.
How do I make the beeps stop and also provide power to both sides?

Do verify that I found the applicable manual.

Regarding the beeps - from the link:

On Battery - UPS is supplying battery power to the load connected to the Battery outlets. Power On LED - ON (off during beep) Beeping 4 times every 30 seconds UPS transfers back to Power On operation, or when UPS is turned off

If that is happening without a power outage then the wall outlet or electrical circuit to that outlet may be faulty.

You may need an electrician to check the power connections.

Came to the conclusion that the UPS is faulty. Put a battery in a different UPS and is working fine.

That happened to me and it turned out the be the circuit breaker on the UPS. I just pressed the button on the right side next to the power cable and everything became fine.
