I should have been more specific with my question lol. Sorry. My real issue was that it was at 89% when there was no outage and the Leoch had been fully charged earlier after performing a runtime test on my freezer.Yes, when the unit has AC power at the input and an AC load, it will simply pass through the AC power (just like a UPS), this means it will show 0 watts output, as that display is only meant to tell you how much power is being supplied by the internal battery. As for the battery "bar" meter, that looks wonky. It should show some bars, if the battery is 89% full, as indicated.
I think the picture may have been a result of coincidence. Unless the battery bar should have shown full bars up to the completion amount with only the amount left blinking.
Thanks
Joe
