Specifications

*Battery voltage and mAh labeling can vary between supplier/revision listings. Check the physical label of your existing battery before ordering.

ASUS’s official parts store currently lists E410MA BATT/BYD PRIS/B31N1912 under SKU 0B200-03680200, providing a useful reference for the B31N1912 part identification.

Is the B31N1912 battery original?

The B31N1912 part number is associated with an ASUS E410MA battery, and ASUS’s official parts store lists an E410MA battery carrying the B31N1912 designation and ASUS SKU 0B200-03680200.

However, the B31N1912 part number alone does not prove that every battery sold under this number is an original ASUS battery. Replacement batteries from third-party manufacturers can use the same compatible part number.

Therefore, if your CARTX product is genuine/original ASUS, customers should verify the ASUS branding, battery label, part number, packaging and supplier documentation. If the product is a compatible aftermarket replacement, it should be clearly described as an aftermarket replacement battery, not as an original ASUS battery.

For additional compatibility reference, iFixit also identifies B31N1912 as compatible with selected Asus VivoBook E410MA and L410MA models, while explicitly identifying its own battery as aftermarket.
