Compatible Replacement Battery

This 80Wh 4-cell lithium-ion battery replaces original Lenovo part numbers 5B10X19049, 5B10X19050, L19M4P71, L19C4P71, SB10X19047 and SB10X19048.

Build Quality and Daily Fit

Premium Li-Polymer cells match the original battery dimensions for a secure fit inside the chassis. Internal circuitry protects against overcharge and short circuit during daily charging cycles. The black housing aligns with the laptop’s existing mounting points so no modification is required.

Bundled Items and Practical Effect

The package includes one replacement battery in secure packaging backed by a 365-day manufacturer warranty. No tools, cables or software are supplied, so installation relies on the laptop’s native battery release mechanism. Buyers needing a multi-bay charging dock or external capacity expansion will not find those functions here.
