View Full Version : Maximum Battery Capacity for different Macs

It seems from this thread (http://forums.macrumors.com/showthread.php?t=477737) 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 (http://www.coconut-flavour.com/coconutbattery/index.html).


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

114135

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.

Abstract
May 1, 2008, 05:45 AM
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.

Eraserhead
May 18, 2008, 05:14 AM
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.

How do you calibrate it?

Use your Mac until the battery runs out, then plug it in until it's fully charged.

Legolamb
Aug 19, 2008, 07:22 PM
Hey Zephead, the MacPro guide is a tad more exact.

To calibrate the battery:
1. Plug in the MagSafe power adapter and fully charge the MacBook or MacBook Pro battery until the light on the MagSafe connector changes to green and the Battery icon in the menu bar indicates that the battery is fully charged.
2. Allow the battery to rest in the fully charged state for two hours or longer. You may use your computer during this time as long as the power adapter is plugged in.
3. Disconnect the power adapter with the computer on and start using it with battery power. When the battery's charge gets low, you’ll see the low battery warning dialog on the screen.
4. Continue to keep your computer turned on until it goes to sleep. Save your work and close all applications when the battery's charge gets low and before the computer goes to sleep.
5. Turn off the computer or allow it to sleep for five hours or longer.
6. Reconnect the power adapter and leave it connected until the battery is fully charged. You may use your computer during this time.

Is there any good program that does something similar to this, but doesn't require 10.4? I'm still running 10.2.8 on my old iBook (well, dual boot with OS9), but I'd like to find out if I'm helping the battery at all by continuing to calibrate it.

I actually created an excel document, and I am plotting out the cycles and capacities. Every month, i'll add new data to the spreadsheet and update the graph. Great way for a trend analysis on the battery.

Sorry if this is in the wrong spot but we are on the subject of max battery capacity.

Ok i have just had my battery replaced under apple care for my Late 2008 MBP. It already has some charge on the new battery. Now do i put that in my laptop, run that down until flat or connect the ac to it and charge then run it down?
