Lenovo ThinkPad X60 Series 4 Cell Enhanced Capacity Battery

The ThinkPad X60 Series 4 Cell Enhanced Capacity Battery can either replace the original 4 cell system battery (select models) or be swapped in as a spare to enable users to stay unplugged longer. It can remain in the system when the system is connected to the ThinkPad X6 UltraBase. Computing for up to 6.1 hours is possible on select systems when the ThinkPad X60 Series 4 Cell Enhanced Capacity Battery is combined with the optional ThinkPad X60 Series Extended Life Battery (40Y7005). Up to 5.6 hours is possible when combined with the ThinkPad Advanced Ultrabay Battery (40Y6789) fitted in the ThinkPad X6 UltraBase. Note that the Extended Life Battery cannot be used in or with the ThinkPad X6 UltraBase. A description of the testing and the environment under which the test was performed is available at www.lenovo.com/pc/ww/thinkpad/batterylife. Battery life (and recharge times) depends on many factors including screen brightness, applications, features, power management, battery condition and other user preferences.
