I'm currently using Late 2008 MacBook (Aluminum). My battery cycle is currently 111 and has went for replacement of battery 6 months ago + warrenty is ending soon. Hence I want to let the battery last as long as possible.
The common question are whether to charge my MacBook when using. But can I charge it for few more hours after it is fully charged? And also charge whenever I found a power source? So that the battery cycle will not increase tremulously.
What are the proper steps to charge MacBook batteries for long lasting life?

The battery cycle is exactly what it says, a cycle. This means that it will count charge and discharge cycles as a whole.
An couple of apple genius guys I talk to recommend at least 2 charge cycles per month, and trying not to leave it plugged in at all times will keep it relatively healthy.
You don't need to completely drain a battery before you charge it either, but the more complete the cycles are, the better accuracy will be on the battery meter.
It's a hotly debated subject, but apple do have information on their website.
