The battery fits only the four models named above. Buyers with other IdeaPad sizes, different series or non-Lenovo laptops cannot use this pack. It is not a universal spare and will not charge in incompatible chassis.

42 Wh capacity for daily mobile use

A full charge supports typical office work, web browsing and video playback for several hours. Runtime drops under heavy CPU or GPU load, discrete graphics use or maximum screen brightness. The 3-cell design limits total energy storage compared to larger 4-cell or 6-cell packs.
