no offence but I would strongly advice against this practice. I have seen the charging circuitry?(or the battery?) dies on notebook whose owner insists of "removing the battery whien connected to the AC power". In 2005, the costs of a Li-Ion notebook batt is about US$100 bux. Is it really worth the hassle of removing / installing the battery frequently? Besides, the cost of replacing the motherboard is more expensive than the battery itself.
Sometimes BAttery will act as an super big capacitor for some electronics device. for example, your car 12V battery acts as a large capacitor to filter out voltage current spike when your motor is running. You can disconnect the 12V battery and the motor still runs fine. However, it may also fry the car's CPU.
My advice use your electronic device in a normal and convenience way you feel more comfortable until the day it calls it in.
Again, YMMV.
