I have a 2.0GHz Core Duo Macbook, and Ive had it for about 3 years. However, is these 3 years, I have gone through 2 batteries. The story goes that about 1 year after I get a new battery the capacity goes down alot. Now it barely holds its charge for 5 mins. My old battery died completely. WTF is going on? Im getting a MBP 13 soon but I just want to know what the **** is happening.

Have you tried resetting the PMU?

Do you often completely drain it and then recharge?

Not often. You think that was the problem?

If thats the case what measures should I take when I get my new laptop so the built-in battery doesnt take a dump on me.

No. If that was the case, I'd think it was the cause. Completely draining and recharging on a regular basis will shorten the battery life. Apple does recommend doing a deep discharge once a month to "calibrate" the battery, but you don't want to do it too frequently.

I know about the calibration. So still now idea as to how this happens? When I get my new Pro Im going to calibrate it in the first day. Then after that charge when ever under 20%, or over night. Is it recommended to keep it plugged in when at a desk, or not using it?
