Overload alarm lights and sound

My ups, after 5 years of continuous operation shows the overload's light .

I unplugged the PC and I replaced the battery but I have not solved the problem.

Then I opened it to see if there are components that are burned or leak but nothing.

To be sure I replaced the cooling fan but nothing has changed.

Can anyone give me some tips?

Thank you very much.

Hi, i had the same problem twice...!!!

My battery was ok, everything was ok but

the beep keep going on, for overload...

Both times i fixed doing these steps...

- Turn off the unit

- Flip over the unit

- Open the battery-cap and turn the power on

- Green Light is flashing

- Try Now (with the green light flashing) to disconnect the battery...

- Now it should be ON with the Empty battery light on (Red light)

- Connect again the battery as it is...

Now it should be ok...!!!

Good Luck...

Thanks to all. I have not solved the problem. I replaced the old ups with a new one.

Roberto, If it alarms, even with nothing plugged in, then it is possible that one of the MOSFET on your mainboard has failed.
