2-power Lenovo IdeaPad S540-15IML Main Battery Pack - Batterie - 52 mAh (2P-SB10W67280)

Unlike generic replacements that merely fit the IdeaPad S540-15IML, this 2-Power main battery pack matches the original Lenovo L18M3PF2, L18C3PF2, and L18L3PF2 specifications exactly. Built around a 3-cell lithium-ion configuration, it delivers 52.5 Wh at 11.4 V, translating to roughly 4600 mAh — enough for a full workday away from the socket, with consistent voltage until the final percentage. The black housing snaps into the chassis without gaps, and the integrated protection circuit guards against overcharge, over-discharge, overcurrent, and short circuits, so the pack stays safe through hundreds of cycles.
