The Lenovo IdeaPad S340-15IWL (81N800T8US) 52.5Wh Original Battery is a high-capacity internal 3-cell lithium-polymer power unit. Designed specifically for the 15.6-inch S340 series, this battery provides the necessary 11.25V output to support the Intel Whiskey Lake processors and FHD displays found in the 81N8 machine type.
At KSh 9,718, this 52.5Wh unit is the certified original replacement for part numbers L18C3PF7, L18M3PF7, L18L3PF3, and 5B10T09094.
