Lenovo ThinkPad X60 Series 4 Cell Slim Line Battery Batterie

Stay unplugged longer with a spare ThinkPad system battery. Replace your original 4-cell system battery (select models) or carry an extra to stay unplugged longer. The Slim Line battery is designed for use with ThinkPad X60s Series notebooks only (Note that it is not compatible with other ThinkPad X60 Series models). Its streamlined form factor ensures a flush fit when you connect your notebook to the optional ThinkPad X6 UltraBase. Interested in staying unplugged even longer? Consider combining the ThinkPad X60s Series 4 Cell Slim Line Battery with the optional ThinkPad X60 Series Extended Life Battery (40Y7005) for up to 5.7 hours (1) of unplugged time on select models. Or, combine it with the ThinkPad Advanced Ultrabay Battery (40Y6789), used inside the ThinkPad X6 UltraBase, for up to 5.2 hours (1) of unplugged computing (Note that the Extended Life Battery cannot be used in combination with the ThinkPad X6 UltraBase).
