Back-UPS Pro 900 sudden battery master backup outlet off

Anonymous user · ‎2021-07-11

One of my Back-UPS Pro 900 units after couple of years of reliable operation is suddenly, for SECOND time lately, NOT providing output on ONE or BOTH battery master backup outlets and the "speaker" button is flashing, the unit being connected to mains and with load around 25% only.

After thoroughly testing the unit offline no any fuctional or battery problems found.

Can this problem be due to overheating the unit during hot summer months or what other reasons are possible?

Any advice about it, please?

Jon, thanks for your comments.

I never activated the green feuture on the particular UPS, since I like to have the connected PC always ON and sleep/hybernation PC functions are OFF as well.

So, I wonder if I activated by accident? or it was on by other means the green function...

Now I have the UPS back working as usual and time will proove if all are OK now.

BTW I disconnected the UPS battery for several minutes as well, to possibly reset it to default settings.
