[ltp] poll: how is your battery? (9-cell-battery lost about 25% capacity in 10 months)

	This is what the battery that came with my T42p reports:

design capacity:         71280 mWh
last full capacity:      66980 mWh

	But according to what I've read, you shouldn't run the battery 
down to as close to 0% as possible, and recharge. THAT kills 
batteries.

	I had a T23 that I judiciously would charge to full, unplug, 
use on battery until 0%, recharge, etc. The battery itself died 
completely 2 days before the 1-year warrantee on it was up. I called 
IBM and they sent me a new one, but told me that the fastest way to 
kill the battery was to force it through more recharge cycles, just as 
I did.
