Compatible replacement for Vivobook Pro 14X

This 63 Wh lithium-ion battery replaces part numbers C31N2019 and C31N2019-1 in select Asus Vivobook Pro 14X OLED M7400 and Vivobook Pro 15 OLED M3500QC models. It supplies 11.61 V and 6427 mAh in a black housing. The unit is new and includes a 12-month warranty.

Upgrade from a worn or swollen original pack

Owners of the listed Vivobook Pro 14X OLED M7400 or Vivobook Pro 15 OLED M3500QC variants should swap the old cell when runtime drops noticeably or the case begins to bulge. The replacement restores the factory 63 Wh capacity without requiring a higher-wattage charger. It is not for users whose laptop uses a different part number or voltage.

Steady output during long work sessions

The lithium-ion chemistry delivers consistent voltage across the discharge curve, supporting sustained workloads such as video editing or compiling code on the 14-inch or 15-inch OLED panels. Capacity holds at 63 Wh over repeated cycles rather than fading after a few heavy bursts. Thermal behaviour remains stable inside the slim chassis.

Questions about this item

Does the C31N2019 battery match the exact dimensions of the original pack in the Vivobook Pro 15 OLED M3500QC-L1062?

The replacement carries part numbers C31N2019, C31N2019-1 and 3ICP6/70/81, which are the direct substitutes for the factory pack in the listed M3500QC models.

What is the common mistake when installing this 11.61 V pack in an Asus ExpertBook B5 B5404CMA?

Many users forget to disconnect the internal connector before removing the old pack, which can short the motherboard; always unplug the battery cable first.

When will the 63 Wh lithium-ion cell need replacing under normal daily use?

The supplier provides a 12 month warranty; after that period a gradual loss of run time signals the cell is reaching end of life.
