If you haven't used that extra battery, it should work find.  If I remember
right, the storage life for a battery is somewhere around 3 years before it
starts degrading.  Of course, I could be wrong, but I'm sure someone will
rebuke me at some point in time :-P

Have you tried resetting the PMU?  There's a little button right beside the
headphone/AV jack that you can stick a pen at.  Pressing that in resets the
power management unit, but it also resets your clock.  Try that and then do
a full battery recalibration (full charge, full discharge, full recharge)
just to see if that helps with the battery you've got.
