Smart-UPS 1500 Mysterious Battery Charge Drop from 100% to 5%

I was very surprised to receive a "Battery Discharged" notification earlier today from one of our older Smart-UPS 1500 units.
It has been working perfectly and had a couple of changes of batter. The last in March 2020.
https://omegle.onl/Everything was fine until that unexpected notification. When I checked in PowerChute it said the batter charge was 5%! Yet how can this be when I received no other notifications. I know notifi vshare cations about going on off batter are working fine, as are notifications such as "AVR Trim Actrive/No Longer Active". So why this sudden "battery discharged" without any warning?
First thoughts would be sudden overload. Yet the data log makes this even more mysterious.
