The Lenovo ThinkPad T490s (20NX) 57Wh Battery is the premium internal power unit designed for Lenovo's flagship slim T-series ultrabook. Specifically engineered for the 20NX hardware series (including the 20NX002JUS), this high-density lithium-polymer battery provides the stable 11.52V output required to sustain 8th Gen Intel Core processors and high-nit low-power displays. As a certified replacement for part numbers such as L18M3PD1 and 5B10W13909, it preserves the ultrabook's incredibly thin profile while restoring its factory-rated mobile endurance of up to 20 hours. It fully supports Lenovo's Rapid Charge technology, allowing the system to regain 80% capacity in approximately 60 minutes when paired with a 65W USB-C adapter. The Lenovo ThinkPad T490s 20NX002JUS 57Wh Battery Price in Kenya is KSh 7,798.
