"For proper maintenance of a lithium-based battery, it's important to
keep the electrons in it moving occasionally. Apple does not recommend
leaving your portable plugged in all the time. An ideal use would be a
commuter who uses her MacBook Pro on the train, then plugs it in at
the office to charge. This keeps the battery juices flowing. If on the
other hand, you use a desktop computer at work, and save a notebook
for infrequent travel, Apple recommends charging and discharging its
battery at least once per month."
