Replacement Battery for Legion 15 and 17 Models

This 80 Wh lithium-polymer pack fits Lenovo Legion 5i 17, Legion 5 15 and 17, and Legion 7 15 series laptops. It replaces part numbers L19C4PC2, L19M4PC2, 5B10W86188, SB10W86197 and SB10W86199. The 6-cell design delivers 15.36 V and 5350 mAh for direct drop-in compatibility.

Ready-to-Install Power Pack

The battery ships new and requires no separate cables, adapters or software. It slots into the existing bay using the original connectors, so the laptop recognises it immediately. A 12-month warranty covers the unit against defects.

Black Polymer Housing with Secure Latch Fit

The black casing matches the chassis colour of supported Legion models. Internal cell layout follows the factory 6-cell arrangement, keeping the same thickness and mounting points. This ensures the bottom cover closes flush and the battery lock engages without modification.

Questions about this item

How many charge cycles before the 80Wh Li-Polymer pack needs replacing?

The 6-cell 80Wh Li-Polymer battery is rated for 12 months of warranty coverage; typical Li-Polymer cells last several hundred full cycles before capacity falls below 80 %.

What is the first limit reached during sustained use — voltage drop or thermal throttle?

The pack delivers a steady 15.36 V at 5350 mAh; under continuous load the voltage sag hits the laptop’s low-voltage cutoff before the cells reach their thermal limit.

Does the 15.36 V 80Wh battery run hot or loud when the Legion 5i-17 runs all day?

The battery itself has no fan and generates only modest heat; any warmth or noise comes from the laptop’s own cooling system, not from the pack.
