Strange that IBM recommends the exact opposite to what I know is good for Li-ion batteries, with the exception of storage in a warm place (like, in a working laptop). The books say that Li-ion will loose very little charge through self discharging (1% per month) so a stored charged Li-ion should stay that way essentially until one needs it. My experience confirms this. F.ex. a charged camcorder battery (not new) still shows 80% capacity after 6 months storage at room temperature.
