Replacement Battery for Asus Zenbook UX530 Series

This new lithium-ion battery replaces the original C31N1622 and 31CP5/70/81 packs in compatible Asus Zenbook UX530, UX430, UX3430 and U5100U models. It restores mobile power for owners whose factory cell no longer holds a useful charge. Buyers needing a higher-capacity pack or a different voltage will not be served by this unit.

Voltage and Capacity Match

The decisive specification is the 11.55V 50Wh rating, which must match the original battery label exactly. A different voltage or watt-hour value will prevent the laptop from charging or reporting capacity correctly. Only the listed part numbers confirm compatibility.

Straightforward Internal Swap

Installation requires removing the bottom case screws, disconnecting the old pack and connecting the new one in the same orientation. The most common issue is forgetting to detach the connector before lifting the board, which can damage the fragile ribbon cable. Ensure all screws are accounted for during reassembly.

Questions about this item

How long will the 50 Wh capacity last in daily use on a ZenBook UX530?

The 50 Wh rating means the battery stores 50 watt-hours of energy; actual runtime depends on the laptop's power draw, screen brightness and workload.

What connector does the C31N1622 use and does it support fast charging?

It uses the original Asus multi-pin connector for the UX530, UX430 and UX3430 series; charging speed is controlled by the laptop's own power-management circuitry.

Will this battery fit inside my UX430UA without modification?

Yes, it is built to the same dimensions as the original C31N1622 pack and slides into the internal battery bay of all listed ZenBook models.
