I tried newmge-shut which has a lot more information available.

I ran a quick battery test with report no error but made the UPS start
beeping and the a deep battery test which really reported an error and
set the RB status and caused upsmon to report a warning message on
console.

This seems to me a hardware bug as the quick test did not report
anything wrong.

I ordered two sets of batteries as my older MGE Ellipse model is also in
bad shape.
This is a good reminder that a test from time to time is good pratice :)
