Notebook Batteries
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.
Good to know, since I mostly use my MacBook Pro as a desktop. After using it on battery for just a few minutes, it takes 1.5 hours or so to get back to a full charge.
