Hello,

Just in case this helps....
Remember that Li-ion batteries have a fixed number of charge/discharge
cycles - in the low hundreds.  If you're draining your battery each time, rather
than staying on the charger, your battery is likely worn out after 6 months.

I try to stay on the charger unless I'm actually on the road.  And when on the
road I recharge as often as possible - full battery discharges wear it out faster 
than smaller ones.  

My A21p still has about 75% of the capacity it shipped with 4 years ago!  But then,
I don't travel much these days.  It's mainly in the docking station.

Good luck,

Don A
