Maximum Energy Reservoir: The 100Wh 9-cell design provides up to 3x the capacity of standard 6-cell (57) batteries. Thermal Optimization: The extended design elevates the rear of the laptop, allowing for superior intake of cool air—critical for the T440p/W540 cooling system. Workstation Stability: Built with premium Grade-A cells that can handle the high-current discharge required by MQ/HQ series processors. Safe Charging Technology: Integrated BMS prevents over-charging, short circuits, and ensures stable voltage across all 9 cells. Frequently Asked Questions Q: Will this fit my standard T440? A: No. This battery is specifically for the T440p (the thicker performance model). The T440/T440s use a different battery system. Q: How much will this battery protrude? A: As a 9-cell battery, it extends out the back/bottom, which provides an ergonomic tilt for the keyboard and better airflow for the workstation’s fans.
