Back-UPS BX700U-GR light briefly turns green followed by a click and a constant beep

[Anonymous user]

Last night my Back-UPS wouldn't start up. All there was was a brief green flash of the power on button followed by a click and a constant beep.

I read that could be because the battery is EOL so I purchased a new one (genuine APC one).

This one does the exact same thing.

What could be the cause?

Thanks in advance!

Hi Daniël,

Could you please try to braindead the UPS. To do this, follow the below procedure:

1: Disconnect any attached load.

2: Unplug the UPS from the wall socket.

3: Disconnect the UPS' internal battery.

4: Push and hold the ""On"" button on the UPS for 5 seconds

5: Reconnect internal battery.

6: Plug UPS in to known good power source.

7: Turn UPS on.

Regards,

Tom
