Can anybody make a recap?
There has been a lot of talk about the calibration issue..
ie. is it a good thing, or a bad thing, to totally deplete a li-ion battery?

I think Fedco officially only sells to resellers.

It seems like it's a bad thing to totally empty li-on batteries. If you look at the macosxhints website, they say that discharging a li-on battery to a state that is too low will cause a special circuit to open which will prevent the battery from being used again. It's a safety issue...something with funky chemistry stuff...yeah. hehe

Though I have another question: from that same website, it says:
"Charge the Li-ion often, except before a long storage"

Does that mean that I should recharge my battery as whenever I use it? I know li-on batteries don't have the 'memory effect'. But does the above quote imply that I can use the battery to say, 90%, recharge...50%, recharge, 70%, rechage, 85%, recharge, and on and on?

Or would it be better to wait till the battery gets nearer to 0 before recharging? (like down to 20-40%)
