Direct replacement for select Asus Chromebooks

This Cameron & Co DS-CS-AUC200NB battery is built for Asus C200MA-DS01, C200MA-KX003, Chromebook C200, C200M and C200MA models. It matches the original B31N1342 part number and delivers 11.4V 4200mAh capacity in a Li-Polymer cell. The unit is brand new and 100% OEM compatible for owners needing a like-for-like power source.

Fits the existing battery bay without modification

The pack measures 265.42 x 86.24 x 6.61 mm and slides into the same compartment as the factory battery. No extra cabling, adapters or firmware steps are required; the Chromebook recognises the replacement immediately. Swapping the old cell restores full mobile runtime and frees the user from staying tethered to an AC adapter.

Single battery unit in black finish

The package contains one black Li-Polymer battery rated at 47.88 Wh. No tools, screws or software utilities are bundled, so the installer must reuse the original fasteners and rely on the laptop’s built-in battery management. Buyers who need a multi-pack kit or an external charger will have to source those separately.

Questions about this item

How long will the 4200 mAh capacity keep a Chromebook C200MA running on a full charge?

The 11.4 V 4200 mAh lithium-polymer pack stores 47.88 Wh, which typically delivers several hours of mixed use on compatible Asus Chromebook models.

Does the battery get hot or make noise during all-day operation?

The Li-Polymer cell has no moving parts, so it runs silently and stays cool under normal loads; only the laptop’s own cooling system generates heat or fan noise.

Which Asus part numbers must match for this DS-CS-AUC200NB to fit?

It replaces Asus battery part B31N1342 (also listed as 3ICP7/60/82) and fits the C200MA-DS01, C200MA-KX003, Chromebook C200, C200M and C200MA models.
