Direct replacement for ZenBook A14 Air

This 70Wh lithium-ion battery replaces part numbers C31N2404 and 0B200-04640100. It fits the ASUS ZenBook A14 Air UX3407QA series and operates at 11.67V with a 6000mAh capacity. The black unit ships new with a 12-month warranty.

Sustained discharge at rated voltage

The cell chemistry delivers 11.67V across the discharge curve rather than spiking higher in short bursts. A 70Wh rating means the pack can supply its rated current for a full hour before voltage drops below the laptop's cutoff. Internal protection circuitry manages temperature and current limits during continuous use.

Single-pack interface constraint

The battery connects through the laptop's proprietary multi-pin connector, so no universal standard applies. Capacity is fixed at 70Wh; the chassis does not allow a second pack or higher-capacity alternative. Users needing longer runtime must rely on external USB-C power banks instead.

Questions about this item

Will the 70 Wh lithium-ion cell run hot or draw extra power during all-day use?

The 11.67 V 6000 mAh pack is a direct replacement for the original C31N2404, so thermal behaviour and power draw match the factory battery under normal workloads.

What must I already own for this battery to work in my ZenBook A14 Air?

You need an ASUS ZenBook A14 Air UX3407QA series laptop that originally uses part numbers C31N2404 or 0B200-04640100; the battery slots in with no extra cables or adapters.

Can I keep my existing charger and internal components when fitting this 70 Wh replacement?

Yes, the replacement uses the same 11.67 V interface and physical layout, so the original AC adapter, motherboard connectors and firmware all remain compatible.
