How to check the battery charge cycle and maximize the battery?

Notebook is battery is notorious for poor and poor performance over time. In day one, you can use your notebook for, say 5 hours, but some months later, the battery cannot sustain the work of an hour or two! So you need to carefully deal with the battery.

"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 notebook 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. "
