    I have a macbook (blackbook) 2.2GHz 1GB Intel machine, that i brought approx one and a half years ago.

    I have checked the battery using both System Profiler and coconutBattery and have found (with the latter) that the battery health is at 96% (was at 97%, then i checked back 10 mins later and it was 96% :( ... its been 96% since) .... what I would like to know is if this is infact a decent decline in battery health over the course of 1 1/2 years, and at what percentage i should think about replacing my battery?

    Thanks in advance guys. :D

    96% health is great battery life for a 1.5 year old computer. My MacBook Pro is about the same age and battery health is in the 80's.

    Thanks for the quick response .... :D

    But just out of curiosity, when would it be advisable to change the battery ( say less than 60%???).

    Cheers iBookG4user :rolleyes:

    Hey, are you insulting my username? :p

    I'd get another battery when it drops to about 50-60% and you can only get 1.5-2 hours when doing light tasks from the battery.

    Is it normal for the battery health to move up and down?

    I noticed how my battery health has now gone up to 98%. Is this usual (is the health supposed to go up and down)? :confused:

    Yes, battery heath will go up and down as you use it. As long as it is not making huge jumps (up or down 10% at a time or more) then you are fine.

    your battery is fine using coconut battery will show the estimated battery health as the program takes into account a number of functions :)

    what you need to worry about is how many hours/minutes you get out of the battery when its not plugged in!

    You can try calibrating, but the only surefire way to increase your battery health is to buy a new battery.

    you cant, the battery degrades over time - you will have to buy a new one.

    if you follow the handy battery guidelines on the apple.support site it will help you maximise your battery life.
