here is a bit of what it says...
For MacBook and MacBook Pro systems with Intel Core Duo processors, this program extends repair coverage on the battery _for up to two years_ from the date of purchase of the computer.
Identifying an affected battery
Affected batteries will have one or more of the following symptoms:
Battery is not recognized causing an “X” to appear in the battery icon in the Finder menu bar.
Battery will not charge when computer is plugged into AC power.
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.
Battery pack is visibly deformed.
so give AppleCare a call and see if you can get your battery replaced.
Good luck,
frank
