The pack fits a wide range of UX550GD, UX550GE, UX550GDX, UX550GEX, UX580GD and UX580GE sub-models as well as U5500G, U555GD and UX534FT units. It will not work in Zenbook models outside this compatibility list or in laptops that require a different voltage or connector layout.

71 Wh capacity for typical daily workloads

At 71 Wh the battery supports several hours of office tasks, web browsing and media playback on a full charge. Runtime drops under sustained heavy loads such as rendering or gaming, and the pack cannot extend beyond its rated capacity without a higher-Wh alternative.

Questions about this item

What laptop models must I already own for the C42N1728 71Wh 15.4V battery to fit?

This battery replaces part numbers C42N1728 and 0B200-02520100 and fits Asus Zenbook Pro 15 models including UX550GD, UX550GE, UX550GDX, UX550GEX, UX580GD and UX580GE series listed in the compatibility data.

Will the 15.4V 71Wh lithium-ion cell work alongside the original charger and power circuitry in my UX580GE?

Yes, the 15.4V voltage and 71Wh capacity match the original specification, so the existing AC adapter and onboard charging controller will recognise and charge the cell normally.

How can I verify the C42N1728 battery is working correctly after I install it?

After fitting the battery, boot the laptop and confirm the OS reports a 71Wh design capacity at 15.4V, then run a full charge-discharge cycle to ensure capacity reads close to the rated figure.
