| | | Up to 1/3 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 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 new, 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. *These model numbers achieved eTesting Labs, Inc's BatteryMark 4.0.1 Battery Rundown Time of at least the time shown.
