    It seems from this thread that a lot of people are asking questions about whether their battery needs replacement. I think its worth improving the Mac Guide on this to make it clear. But to do so I need to know the maximum battery capacity of a selection of Macs which can be found with Coconut battery.


    Please post the original capacity for your Mac below with the Model as well.

    I'll start with the MacBook 13": 5200mAh.

    EDIT: Please include the screen size otherwise the data can't be used

    For some reason, CoconutBattery mistakenly reports that MacBooks have a 5020 mAh capacity when in reality they're 5200 mAh. I noticed this when I upgraded to Leopard and noticed my original capacity had dropped to 5020, so I changed it in the CB prefs.

    Nice catch, fortunately I remembered it was 5200 and didn't notice what it actually said :).

    iBook G4 12"

    Pretty sure the "current battery capacity" is the real one.

    If the battery needs replacing, you'll know. Capacity decreases of lithium ion batteries decrease very slowly, but after 2 or 3 years, or a certain number of charge cycles (around 300, on average), battery life will just start free-falling until you get less than 1 hour per full charge. This sudden drop from "good" battery life, to a miniscule battery life will happen within a span of several months. Once you start seeing this accelerated drop in battery life, you need to start thinking about getting a new battery. Otherwise, your battery will have little capacity in several months.

    Is that enough information?

    ^^ Yeah, but that won't stop the threads, <shrug> it seems useful to have the figures for people to compare.

    I've added the MacBook Pro 15" and MacBook 13.3" figures of 5200 and 5500 mAh, the others I've calculated manually, as I believe 2100 is way too low for the iBook when Apple claim they have similar battery capacity to the PowerBook's.

    Yep, 17". It's the final revision PowerBook - the one that lasted all of three months before the Intel laptops were announced :rolleyes: - if that helps any.

    Thought I'd share this: I last posted here on May 17th, with my 17" PowerBook getting 1517 mAh; just ran CoconutBattery again, got the following results:

    ^^ Its normal for it to fluctuate. But what I was looking for was the original capacity not the final capacity.
