After 8 years, my UPS finally failed me w/ a sudden "F03" error

First, I get a lot of F02 and F03 errors

As others have stated, when you get an F03 error the UPS drops the load which cuts power to everything the backup side is attached to with no warning

The latest one F03 error which does not come up in any online FAQ but seems to be the same as APC error which is a failure in the overload circuit and thus a dead UPS2 Stars... they work but they will die, even if you a small load and treat them well.

2 weeks later, I got the F03 error again yesterday

I bought this in Dec of 2017 and 2 weeks ago got the F03 error

The second lasted 6 years, until I got the common and dreaded "F03" error

3 year warranty, died with f03 error in 3 years and 1 month.

It alerts you with an F03 error and dumps the load immediately.

My UPS Lasted 11 years before giving me the F03 error indicating it can no longer charge the battery
