Replacement battery for Lenovo IdeaPad 3 series

This GreenTechLLC L20M3PF0 battery fits a wide range of Lenovo IdeaPad 3, S14, V14, V15 and V17 models. It is a three-cell lithium-ion pack rated at 11.1 volts and 4054 milliampere-hours for 45 watt-hours of capacity. The part replaces OEM numbers including 5B11B36279, 5B11B36283, L20C3PF0 and SB11B36274. It is a new, non-OEM unit supplied in black.

Upgrading from a depleted or failing original pack

When the factory battery no longer holds a useful charge, this unit restores the original runtime specification. The jump is worth it if the laptop otherwise meets your needs but shuts down early or reports a service warning. It matches the voltage and cell count of the original design, so no hardware changes are required beyond the swap.

45 Wh capacity for typical mobile workloads

The 45 watt-hour rating supports everyday office tasks, web browsing and video playback on the compatible 14, 15 and 17 inch chassis. Heavier sustained loads such as gaming or rendering will exhaust the pack more quickly, and users needing all-day runtime without a charger should plan for external power. The three-cell design keeps the form factor identical to the stock battery.

Questions about this item

Does the L20M3PF0 battery match the physical dimensions of the original 3-cell pack for my IdeaPad 3-14ITL6?

Yes, it is built as a direct 3-cell replacement with the same 11.1 V form factor used in the IdeaPad 3-14ITL6 and other listed models.

Which screw or latch do I release first when swapping the L20M3PF0 into an IdeaPad 3-15ALC6?

Remove the bottom case screws, disconnect the old battery cable from the motherboard before lifting the pack out, then connect the new battery before refitting the case.

How will I know when the 4054 mAh cells in this pack need replacing?

When run time falls well below the original 45 Wh rating or the system reports a significant capacity loss, the cells are due for replacement.
