Compatible Lenovo Chromebook Battery

This GreenTech replacement battery fits Lenovo Chromebook 100e and 500e models including Gen 3 and 2nd Gen MTK variants. It replaces multiple OEM part numbers such as L20L3PG2 and 5B11B36309. The 3-cell lithium-ion pack delivers 11.4V and 42Wh capacity for compatible devices.

Straightforward Internal Installation

Installation requires opening the Chromebook case and disconnecting the original battery before connecting the new pack. The connector matches the OEM layout so no adapter is needed. Common issues include forgetting to detach the bottom screws or not seating the ribbon cable fully, which can prevent the system from recognising the battery.

42Wh Capacity for Daily Classroom Use

The 3735mAh rating provides enough energy for a typical school day of web browsing and document work on supported Chromebooks. Runtime drops noticeably when driving external displays or running Android apps continuously. Users needing all-day operation without a charger should verify their specific model's power draw before relying on a single charge.

Questions about this item

How can I confirm the 11.4V 42WH battery is working correctly after installation?

The Chromebook should power on without the AC adapter, show the 42WH capacity in the OS battery settings, and run for a typical session without unexpected shutdowns.

What comes in the box and what must I source separately?

The box contains the 3-cell lithium-ion replacement battery only; you will reuse the existing screws and connectors from the Chromebook 100E or 500E Gen 3.

Which part number matches my Lenovo Chromebook 100E Gen 3 82UY?

This battery replaces OEM numbers 5B11B36309, 5B11B36314, 5B11B36317, L20L3PG2, L20M3PG2, L20D3PG2, SB11B36316, SB11B36318 and SB11B36322, all listed as compatible with the 100E Gen 3 82UY.
