Compatible Asus Vivobook and S-series models

This Cameron Sino DS-CS-AUX402NB battery replaces the original power pack in a wide range of Asus Vivobook and S-series laptops. The list covers models such as the S300, S300CA, S400CA, AR5B225, F402CA, R407CA, R408CA, V300CA, V400CA and several VivoBook N550 and S300C variants. It is built for owners of those specific machines who need a direct-fit replacement.

Simple internal swap with connector care

Installation requires opening the laptop base and disconnecting the old pack before fitting the new one. The battery uses a proprietary multi-pin connector that must be aligned and pressed in fully; a partial seat causes the system to report no battery detected. No soldering or firmware updates are needed, but the retaining screws are small and easy to drop inside the chassis.

Check your exact model code before ordering

Verify the full model name printed on the bottom sticker or in the BIOS against the compatibility list supplied. Some Vivobook S300 and S400 sub-models use a different battery shape or connector pin-out even though the series name matches. The replacement is a 4 Ah lithium-polymer unit in black; if your original carries a different capacity or colour code, this pack will not fit or charge correctly.
