Recharging is definitely a problem since a fully charged battery does lose some of its charge while not being used. A few days is not a problem but a few weeks will leave your battery weak at the knees if not recharged before use. If I know I am going to be using the notebook as a portable I slip the battery in the day before or even a couple of hours before leaving AC power behind.

Not a great solution but my notebook batteries last much, much longer now.
