Battery life

[Rchawks]

Should MacBook Pro owners always use the battery source as opposed to AC.
Having the battery soldered in removes the option of operating in AC only mode which I prefer. However, I do understand that a battery is like a muscle and it's use it or lose it kind of thing. However having it connected using my HP allows for a brighter screen. Does using the laptop with a fully charged battery while connected to AC degrade the battery in any way, even though there is a auto cutoff for the battery charge. Can anyone give an idea of what the average user does.

When the power adapter is connected, the battery is idle. You can safely use the power adapter without damaging your battery, as battery technology has evolved in the past decade and that notion of batteries dying when connected to a power source is a bit old.
