Replacement Battery for Lenovo Chromebook 14e

This lithium-ion battery replaces part numbers L18M3PG2, L18L3PG2 and L18D3PG2 for Lenovo 14e Chromebook Series and Chromebook S345-14AST Series laptops. It delivers 11.52V and 57Wh capacity in a black housing. The unit is supplied new and includes a 12-month warranty.

Voltage Fixed at 11.52V With 57Wh Capacity

The battery operates at a fixed 11.52V and stores 57Wh of energy, equivalent to 4955mAh. Runtime depends entirely on the laptop's power draw and workload. No higher-capacity alternative is offered for these models, so users needing longer unplugged time must rely on external power banks or reduced screen brightness.

Simple Internal Swap With Connector Alignment Risk

Installation requires opening the Chromebook base, disconnecting the old pack and connecting the new one using the existing cable. The main difficulty is aligning the multi-pin connector without bending pins; forcing it can damage the motherboard header. No adhesive removal is mentioned, but screws securing the bottom cover vary by chassis revision.

Questions about this item

Which of the L18M3PG2, L18L3PG2 or L18D3PG2 part numbers should I pick for my Lenovo 14e Chromebook?

The three part numbers are cross-compatible; the supplier ships whichever is in stock and all replace the original 5B10T04979 and 31CP5/87/69 batteries.

What runtime can I expect from the 57 Wh rating once the battery is installed in a Lenovo Chromebook S345-14AST?

The 57 Wh capacity matches the original specification, so you should see the same run time the laptop delivered when it was new.

Does the 11.52 V voltage limit compatibility to only certain Lenovo 14e or S345-14AST models?

The supplier notes that L18M3PG2, L18L3PG2 and L18D3PG2 are compatible with each other despite voltage differences, covering all listed 14e and S345-14AST units.
