Greetings Jorgensen:
The batteries could be both getting old, and also needing a complete cycling
to reset the values. In my bios, I have a special *mode* that completely
discharges the batteries, then charges them completely and *learns* the
cycle, then repeats the procedure. Yet as batteries age, they will give less
service life.

Hi all!
Just a bit curious. What happens when Li-ion batteries age? They have no
such "memory" as the older NiCad batteries. Perhaps it will work with a
recondition procedure, but with Li-ion, I am a bit sceptical.
The discharge curve seems ok, since it will drop faster as the battery
looses charge, but maybe the time is a bit short. With no (or little)
energy saving options, the battery probably will last no more than an hour
and a half at anyway. The charge curve is odd I must confess, but some of
that behaviour probably originates from the measurment of the battery
power. There could rather be a problem there.
How old is the battery? How many recharges has it been through?
