Macbook bought Aug 07; still has 100% battery health?

[Khryz]

I was just curious about this. I am NOT complaing, lol -- but I've read some posts and threads about people who's battery health has been going down after a couple months. I have completed I think (at work now) around 215 cycles. Is this normal? I always put my computer to sleep at night and only take it off the charger a couple times a week to get down to 30-40% and then I charge it back up.

Sounds like whatever program you are using to give battery status is giving you a false reading. It is physically impossible for a 1.5 year old battery that has gone through 215 cycles to have not lost any efficiency/energy.

Are you using coconutBattery?

I'm using the iStat Pro widget. I checked in System Profiler and it says the health is "Good".

Try coconutBattery, see what that tells you.

i have a MacBook that was bought in May of 2007 and cocoanut battery tells me that I have 100% battery life...I wouldn't use it, but that's me

If you re-calibrate your battery, I'm confident that the 100% will drop quite a bit. Like someone stated, it is impossible for a battery that had that many charges stay at 100% battery health.
