This high capacity battery has an extended area on the back edge and fits in the standard ThinkPad T40/R50 system battery slot. Its compatible design allows it to be in the system when the system is connected to Dock II, Mini-Dock, and Port Replicator II and it can be recharged with the optional external ThinkPad Multiple Battery Charger II. All-day computing is a reality (up to 8 hours on select systems)* when you combine the ThinkPad T40/R50 Series High Capacity Li-Ion Battery with the optional ThinkPad Ultrabay Slim Li Polymer Battery. Battery life (and recharge times) will vary based on many factors including screen brightness, applications, features, power management, battery conditioning, and other customer preferences.
