My old G3 was secondhand and by the time I got it the battery was shot. To avoid this happening with my new PB I would like to know how often should you run down your battery?
Apple Support says:
"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 iBook 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."
But if once a month is the minimum requirement, what's the ideal? The more the better? Or can you overdo it?
(Unless you have a five hour train ride to work, Apple's definition of an ideal user does not tell you how often you should run the battery right down)
