Professional Series Replacement Battery

This Dr. Battery Professional Series unit is a direct replacement for Lenovo ThinkPad P40 Yoga and ThinkPad Yoga 460 Series laptops. It matches original part numbers 00HW020, 00HW021, SB10F46458 and SB10F46459. The lithium-polymer cell operates at 11.4V and is built for business professionals and mobile users who need dependable daily power.

3600 mAh Capacity and Safety Headroom

The 3600 mAh capacity provides stable runtime for typical office workloads and mobile productivity. Integrated safety circuitry protects against over-charge, over-discharge, overheating and short-circuit. Heavy continuous loads or ageing cells will reduce available runtime, so users with high sustained power demands should plan for more frequent charging cycles.

Upgrade from Worn Original Battery

This battery replaces a degraded or failed original unit, restoring full mobile operation without tethering to an AC adapter. The jump is worth it when the existing battery no longer holds sufficient charge for a work session or shows swelling. It is not for users needing higher capacity than 3600 mAh or compatibility with other laptop models.
