Direct replacement for ASUS ZenBook 14

The KingSener C41N1904 is a new lithium-ion battery built to match the original specifications for ASUS ZenBook 14 models UX425UA, UX425IA and UX425EA. It delivers a 67Wh capacity at 15.48V using grade-A cells and a factory-calibrated protection board.

Capacity rated at 67Wh and 4210mAh

The single figure that determines compatibility is the 67Wh / 4210mAh rating at 15.48V, which matches the OEM design capacity printed on the original C41N1904 label. If your existing battery shows a different watt-hour or milliampere-hour value, this unit will not be the correct fit.

Low heat output under normal loads

In typical office use the pack runs cool because the internal resistance of the Li-ion cells stays low at moderate discharge rates. The protection circuit limits current spikes, so the battery adds no audible noise and draws only the power the laptop requests, keeping thermals stable during everyday workloads.

Questions about this item

How long will the 67Wh capacity actually run my ZenBook 14 UX425?

The 67Wh rating matches the original design capacity so real-world runtime equals a new factory battery; actual hours depend on your workload, screen brightness and power settings.

Does the 15.48V voltage limit which ASUS models can use this battery?

Yes, 15.48V is the exact voltage required by ZenBook 14 UX425UA, UX425IA and UX425EA; using it in a laptop expecting a different voltage can cause damage.

Will the C41N1904 fit my UX425 without modifying the chassis?

It is built to the same dimensions as the original ASUS battery, so it seats in the existing bay and uses the original screw points with no adaptation needed.
