Battery Update 1.3 updates battery firmware and addresses battery performance issues with the 15-inch MacBook Pro.
System Requirements
Installation of Battery Update 1.3 requires Mac OS X 10.4.10 or later.
The Battery Update 1.3 supports the following products:

Note: After Battery Update has been installed, each battery you insert into your 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 at least 30 seconds after inserting the battery, or wait 30 seconds after you've logged in with a user account, before checking to see if the battery was updated.
