NShi L20M4PE1 75WHR replacement battery

This new GreenTech lithium-ion pack is built for Lenovo IdeaPad 5 Pro, Slim 7 Pro, Yoga Slim 7 Pro and ThinkBook 16p models that require a 15.36V four-cell unit. It replaces OEM part numbers SB11B66551 through SB11B66556 and L20M4PE1, so owners of those machines can restore original runtime without an OEM purchase.

Voltage and cell-count constraints

The battery delivers 15.36V from four lithium-ion cells, matching the electrical spec the listed laptops expect. A pack with a different voltage or cell count will not fit the charging circuit, so this unit is limited to devices designed for that exact 15.36V four-cell configuration.

4883mAh capacity and 75WHR energy

At 4883mAh the pack stores 75WHR, which covers typical office and media workloads on the compatible 16-inch models. Heavy multi-core rendering or sustained gaming will draw the reserve faster, so users needing all-day unplugged runtime under load should keep a charger or a second battery available.
