Replacement battery for ASUS Vivobook Pro models

The KingSener C31N2105-1 is a 70Wh 11.61V lithium-ion battery built to replace the original pack in compatible ASUS laptops. It fits the Vivobook Pro 15 OLED K6502 series, the Vivobook Pro 14X OLED N7401 series and the Gaming Vivobook K3605 series. The unit ships new and ready to install.

Thermal behaviour and power delivery

The 6072mAh cell delivers the rated voltage without additional cooling requirements. Normal operation stays within the thermal envelope of the original design so fan curves and surface temperatures remain unchanged. No extra power draw is introduced beyond the factory specification.

Physical fit and daily implications

The black housing uses the exact screw-hole pattern of the C31N2105-1 part number; the similar C31N2105 has different mounting points and will not align. Verifying the model printed on the old battery before purchase avoids a mismatch. Once seated the pack locks securely and the connector mates without force.
