Yes, longevity is reduced by storage *without regard for topping up

Interesting. Across one cell, it drops from 5.4V to 2.8V, when initially
plugged in, then after the UPS chirps and dies, it gradually rises again. Not
sure what's going on here.

It's testing the batteries. And then saying "You are kidding!". A lot
of APC units will play dead when confronted with shot batteries. No point
powering up if there's no actual battery backup to rely on
