  • 52 V Li-ion chemistry delivers stable voltage for consistent performance
  • Up to 500 recharge cycles extend usable life across multiple school years

Replacement Battery for Lenovo Chromebooks

This 47Wh lithium-ion replacement battery fits Lenovo 100e and 300e Chromebook 2nd Gen models as well as the Ideapad 3 CB-11AST05. It operates at 11.52 V and provides 4125mAh capacity. The unit is new and includes multiple safety protections.

Capacity and Cycle Life

The 47Wh rating delivers a full day of typical classroom or office use on a single charge. Rated for up to 500 recharge cycles, the battery maintains usable capacity through extended daily charging routines. Performance tapers off after the cycle limit is reached.

Upgrade from Degraded Original Cells

This part replaces worn or swollen factory batteries carrying codes such as L19C3PG1, L19M3PG1, L19L3PG1 and the 5B10X and 5B11A series numbers. The jump is worth it when the original pack no longer holds a charge through a school day. Buyers needing higher capacity than 47Wh or a different voltage must look elsewhere.

Questions about this item

Will this 11.52 V 47 Wh battery fit alongside the original charging circuitry in my Lenovo 300e Chromebook 2nd Gen AST 82CE?

Yes, it matches the original L19C3PG1 and 5B10X65682 codes, so the laptop's existing power management recognises it without modification.

How can I confirm the 4125 mAh replacement is charging correctly after installation?

The Chrome OS battery indicator will show the charge percentage rising normally and the battery health tool will report a design capacity near 47 Wh.

Does the package include the 5B11A25390 screw kit or only the Li-ion cell?

Only the battery is supplied; mounting screws and any opening tools must be sourced separately.
