JPWEB C31N1841 11.55V 50Wh laptop battery for ASUS ZenBook 14

50 Wh Li-Polymer replacement for ZenBook 14

This 11.55 V, 50 Wh lithium-polymer battery replaces the original C31N1841 unit in compatible ASUS ZenBook 14 models. It is built with Grade A cells for reliable charging and low power draw. The pack suits owners of UM433DA, UX334FL, UX434DA, UX463FA, UX463FL and ZenBook Edition 30 laptops needing a fresh power source. It is not for users whose machine uses a different part number or voltage.

Capacity and runtime headroom

Rated at 50 Wh and 4210 mAh, the cell delivers the same energy reserve as the factory battery. It comfortably powers typical office workloads, web browsing and video playback for a full workday on a single charge. Runtime shortens under sustained heavy loads such as rendering or gaming, where the 50 Wh limit is reached faster. Buyers needing longer unplugged time than the original design allows will not gain extra capacity here.

Installation fit and system impact

The battery matches the OEM form factor for the listed ZenBook 14 chassis, so no case modification is required. It connects to the existing motherboard header without extra cables or adapters. Replacing a degraded pack restores original battery life and removes the need to stay tethered to an AC adapter. Technicians should observe anti-static precautions during the swap; no firmware update or BIOS change is mentioned in the specifications.
