What this battery replaces

The KingSener C22N2107 is a 75WH lithium-ion replacement battery built for the Asus ZenBook 14 OLED UX3402 series and related UM3402 models. It matches the original 7.74V voltage and 9702mAh capacity so the notebook recognises it without calibration issues. Owners of compatible ZenBook 14 units from 2022 onward can swap the old pack and regain full mobile runtime.

When the upgrade makes sense

If the factory battery no longer holds a charge through a typical workday or the system throttles because of worn cells, this unit restores the original endurance. It also suits repair shops that need a new, warrantied pack for the listed UX3402ZA, UX3402VA and UM3402YA model families. Buyers whose laptop uses a different part number or voltage should look elsewhere.

Behaviour under sustained load

The 75WH capacity delivers consistent energy during long sessions such as video playback, compilation or light creative work without the sharp voltage drop seen in aged cells. Li-ion chemistry maintains stable output across the discharge curve, so performance stays predictable until the reserve is low. The pack is rated for everyday cycling rather than high-current bursts.

Questions about this item

Does the C22N2107 battery match the exact dimensions of the original Asus ZenBook 14 OLED UX3402 pack?

This replacement is built to the same 7.74 V, 75 Wh specification as the original C22N2107 / 0B200-04160000 pack, so it fits the UX3402, UM3402 and Q409ZA chassis without modification.

What is the correct order for disconnecting and reconnecting the battery connector during installation?

Power off the laptop, unplug the AC adapter, open the base cover, disconnect the battery cable from the motherboard first, swap the pack, then reconnect the cable before closing the cover.

How can I tell when this 9702 mAh Li-ion pack needs replacing?

When runtime drops well below the original 75 Wh rating or the system reports a significant wear level, the cells have aged and a new C22N2107 unit should be fitted.
