Question about Macbook Battery

[krayziekray]

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.

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 ....

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

Hey, are you insulting my username?

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)?

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!

Cool, thanks!!!

Well, I'm getting approx 3.5 hours to 4 hours (at best) from my macbook. Thanks for your help.

Also, checked once again, battery is now at 100% .... sweeeet

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.
