THINKPAD 9-CELL LI-ION CPNT SL400 SL500 R60 R61 R500 T60 (15 4)

Up to one-third more capacity than the standard system battery. This high-capacity battery has an extended area on the back edge and fits in the standard ThinkPad Z60m system battery slot. It's design allows it to remain in the system when the system is connected to the ThinkPad Advanced Dock, Advanced Mini-Dock or Essential Port Replicator. Battery life (and recharge times) depends on many factors including screen brightness, applications, features, power management, battery condition and other customer preferences.
