Got an issue where the UPS is randomly tripping. The battery in the unit has failed and is showing the replace battery LED.
The battery charge LED will show that the battery is fully charged but then after a trip it shows as empty and the bottom charge point LED is flashing green. It is now solid green so I am guessing it is charging again...
What I don't get is why the unit would trip even though the battery needs replacing if there is not a power cut?
Shouldn't the unit continue to function even if it is only filtering and surge protecting connected devices? surely it should not trip?
