Battery Update 1.2 for MB/MBP

3074 Views 11 Replies 7 Participants Last post by  HowEver or run Software Update. :)

Battery Update 1.2 updates battery firmware and improves battery functionality.

System Requirements

Installation of Battery Update 1.2 requires Mac OS X 10.4.8 or later.

The Battery Update 1.2 supports the following products:

MacBook (Late 2006)
MacBook Pro (15-inch)
MacBook Pro (15-inch Glossy)
MacBook Pro (15-inch Core 2 Duo)
MacBook Pro (17-inch)
MacBook Pro (17-inch Core 2 Duo)
Note: After Battery Update has been installed, each battery you insert into your MacBook or MacBook Pro will be updated automatically.

When will the battery be updated?

The BatteryUpdater will check to see if a battery needs to be updated on startup, wake from sleep, and when a battery is inserted. If in these cases there is no AC power supplied, it will then wait until AC power is present and then check to see if the battery needs to be updated. If the battery needs to be updated it will update it automatically. Wait 30 seconds before you validate the installation.

What the heck does that mean?
It means the effects of the battery update are not instantaneous. ;)
Batteries need firmware updates?? What did they put in there Core Solo processors to control the battery?
This update also comes with the caveat that if your battery "exhibits low charge capacity/runtime when using a fully charged battery with a battery cycle count (as shown in System Profiler) of less than 300." then you can contact Apple and get a new one.

My Macbook never gives me more than 2.5 hours and that's with screen at half brightness. Is that normal? I've always thought that was kinda low. Wonder what Apple's definition of "low charge capacity" is. ;)
What are you doing in those 2.5 hours?

On my iBook I was able to surf the net with screen low on WiFi for 5.5 hours. Play Unreal 2003 for 3.5 hours. It was awesome. My MBP gets around half that. :(
I have a cycle count of 7, since November (I rarely take it out of the house.. no reason to) and I get 3.5 hours (so says the indicator) with 1/2 brightness and Wifi on.
How do we know if the battery's updated?

See the Apple Knowledge Base link in the first post? Click on it.
I have a 3 month old macbook and I swear the first time I used it It ran on battery power for over 6 hrs. and that was using wifi constantly. Now i'm lucky if I get a couple of hours. it's already down to 88 % capacity in 3 months. is this normal?

Huh. That's odd. When I navigate to the SystemConfiguration folder, and find the "BatteryUpdater.bundle", it shows up as a FOLDER instead of a BUNDLE.

Doing a "Get Info" reveals a kind: Folder instead of a kind: Bundle

And I can't check the Version Number because... well, it's a Folder.


I did a permissions repair both before (many repairs) and after (none) the installation, which of course involved a reboot.

Hmmmmm. So... does this mean that none of the Bundles are actually... well, bundling anything? None of the "bundles" in that folder are seen as Bundles - they're all Folders.

Just noticed this:

Apple also notes that Intel Core Duo-based MacBooks and MacBook Pros gain an additional two years of warranty protection for the battery.
Nice touch.
