This may sound strange but have that battery tested on a load tester.  A
FLAPS big inside the store battery tester, not the handheld
battery/alternator tester used at some flaps like autozone.  The big ones do
load testing at several test points of charge.  Or use an actual battery
load tester, these are hand held (but can get very hot).  I have seen
batteries that have enough to kick over the starter but would actually be
down to about 10 volts with little or no recovery.  Dirty contacts at the
battery or at the starter lug connection between the alt lead and the
battery lead can cause problems as well with charging, though not usually
this symptom.
