80 Wh lithium-ion replacement battery

This 7.8 V, 10260 mAh lithium-ion cell replaces the original power pack in Lenovo YogaBook 9-13IMU9 (83FF) and YogaBook 9-13IRU8 (82YQ) series 2-in-1 laptops. It restores full mobile runtime for users whose factory battery no longer holds a charge.

Voltage and capacity define the practical limit

The 7.8 V nominal voltage and 80 Wh capacity set the energy ceiling; the laptop’s power management cannot draw more than the cells store. Runtime scales with workload, screen brightness and background tasks, so heavy multi-tasking will deplete the pack faster than light browsing.

OEM-grade cells with safety certifications

Built from OEM-grade lithium-ion components, the pack carries CE, FCC, UL and RoHS certifications for electrical safety and substance restrictions. The connector position and cable length must match the original L22M4PH0, SB11K39336, 5B11K39337, SB11N45421 or 5B11N45437 part exactly; verify alignment before fitting.

Questions about this item

How do I confirm this 80Whr 7.8V 10260mAh 4-cell battery is the right replacement for my YogaBook?

Match your original battery to part numbers L22M4PH0, SB11K39336, 5B11K39337, SB11N45421 or 5B11N45437 and verify the connector position and cable length against the product photo before ordering.

What runtime can I expect from the 80Whr capacity once installed in a YogaBook 9?

The 80Whr rating means the pack stores 80 watt-hours of energy; actual runtime depends on your YogaBook 9-13IMU9 or 9-13IRU8 power draw, screen brightness and workload.

Does the 7.8V lithium-ion 4-cell design require any specific charging protocol or firmware handshake?

The battery uses standard 7.8V lithium-ion chemistry and is built to OEM specifications with CE, FCC, UL and RoHS certification, so it charges through the laptop's normal power-management system.
