Who this suits and who should look elsewhere
Owners of the listed ThinkPad models needing a direct-capacity replacement will find the correct voltage and connector. Buyers with other ThinkPad series, non-Lenovo laptops, or machines requiring a higher-capacity pack should look elsewhere. The battery is not compatible with systems outside the explicit model list, and no adapter or converter is included.
Capacity, runtime and limits
The 48 Wh rating delivers typical office runtime for the supported ultraportable and mobile-workstation chassis. Heavy workloads, high screen brightness or attached peripherals will reduce usable time. The pack does not extend beyond the original factory capacity, so users expecting all-day operation under load may need to carry a charger or a second battery.
