Replacement battery for Asus ZenBook UX330 series

This Dr. Battery MPL03318P-20 is a new lithium-polymer pack rated at 4800mAh and 57Wh with an 11.55V output. It replaces the original C31N1602 cell used in multiple ZenBook UX330U and UX330UA sub-models. A built-in smart control chip manages charging, discharge and protection against short circuit, overheat and overload. The unit ships in black and carries a one-year manufacturer warranty.

Who should buy this and who should not

Owners of the listed Asus ZenBook UX330U or UX330UA variants needing a direct voltage and capacity match will find this part fits the original specification. Buyers with other Asus series, different UX model numbers, or laptops requiring a different voltage or connector layout must look elsewhere. The pack is not suitable for devices that use a higher-capacity or lower-voltage design.

Deciding spec: 11.55V / 57Wh capacity match

The single figure that confirms compatibility is the 11.55V 57Wh rating paired with the C31N1602 part reference. If your original battery shows the same voltage and watt-hour value, this replacement will meet the OEM power profile. If the label on your old pack differs in either number, the battery will not work correctly.

Questions about this item

How long will the lithium-polymer cells in this MPL03318P-20 pack last before I need to replace it?

Lithium-polymer cells gradually lose capacity over hundreds of charge cycles; keeping the battery between 20 % and 80 % charge and avoiding high heat extends its useful life.

What is the first limit I will hit when running the 57 Wh battery continuously on my ZenBook UX330UA?

The 4800 mAh capacity at 11.55 V defines the total energy available, so runtime ends when the pack reaches its low-voltage cutoff.

Does the built-in smart control chip make the battery run hot or noisy during all-day use?

The pack has no moving parts and the protection chip only monitors voltage and temperature, so it stays silent and adds negligible heat.
