Replacement battery for Lenovo Chromebooks

This 42Wh lithium-ion battery replaces the L20D3PG2, L20M3PG2 and L20L3PG2 packs used in IdeaPad Flex 3 Chromebook-11IJL6, Chromebook-11M836 and IdeaPad 500e Chromebook 3rd Gen models. It delivers 11.25V and comes in black. The unit is supplied new with a 12 month warranty.

Upgrading from a depleted original pack

If the original battery no longer holds a useful charge or the laptop only runs while plugged in, this replacement restores mobile operation. The part numbers 31CP5/54/90, SB11B36316, 5B11B36317, 5B11B36309 and 5B11B36314 are all covered. The jump is worth it when run time has dropped below your daily needs.

Check the part number before ordering

Verify that your current battery carries one of the listed part numbers or that your laptop model appears in the compatibility list. The supplier notes the three model variants are cross-compatible despite voltage differences and will ship whichever is available. If your part number is absent, contact the seller to confirm fit.

Questions about this item

Will this battery fit the Lenovo IdeaPad Flex 3 Chromebook 11IJL6 chassis?

The replacement is listed as compatible with the IdeaPad Flex 3 Chromebook-11IJL6 series and matches the original SB11B36316 part number for that chassis.

What is the correct way to install the battery, and which step is most often missed?

Power off the Chromebook, disconnect the AC adapter, remove the bottom case screws, unplug the old battery connector before lifting it out, then connect the new battery before reassembling; the step most often missed is unplugging the old connector first.

When will the 42Wh lithium-ion pack need replacement?

A 42Wh lithium-ion cell typically delivers useful runtime for 12 months under daily charge cycles; plan to replace it once run time drops below half of the original figure.
