    An interesting post:

    Lenovo Support & downloads - Lenovo Battery Firmware Update Utility Dependency Wrapper for Windows 7 (32-bit, 64-bit), Vista (32-bit, 64-bit), XP (32-bit) - ThinkPad

    "This battery firmware update utility fixes an issue where some batteries indicate an incorrect full charge capacity value. Because of this error, the amount of energy available for use is artificially low, decreasing the amount of time the system can be used on battery. The fix is entirely contained in the battery firmware update; there is no need to replace any hardware for this problem."

    Another issue is that there are reports that Windows 7 has a tendency to inaccurately report battery capacity in some laptops. I don't know if this has been resolved yet or not.
