It won't make all that much difference. The only thing that drains the battery life is temperature. The more tha laptop heats, the more the battery drains. The best thing that we can do is to remove the batteries while at home and to keep it somewhere cool.
If it's a Li-ion battery, then they don't like to be completely discharged, so make sure you charge them regularly.
Wikepedia: Li-ion batteries should not be frequently discharged fully and recharged, but this may be necessary after every 30th recharge to recalibrate any electronic charge monitor (e.g. a battery meter). This allows the monitoring electronics to more accuratley estimate battery charge. And this has nothing to do with the memory effect.
