This information is for a lithium ion battery, while the battery in the nook is a lithium polymer battery, which has different charging preferences. Lithium polymer can't be trickle charged, so short charge cycles are not recommended. I couldn't find any hard-and-fast rules about repeat full discharging, but I would imagine it's best to plug in between 5% and 40%, and avoid plugging in when the unit is more than 75% charged. Also, leaving the nook plugged in for long periods of time won't keep the battery charged, because the device shuts off charging at a certain point (it never truly reaches "100%"), so unplug it when it's finished charging and let it drain before plugging it back in.
