Direct Replacement Battery

The KingSener C31N2019 is a 63Wh 11.61V lithium-ion battery built to replace the original pack in Asus VivoBook Pro 14X OLED M7400 and 15 OLED models. It matches the factory voltage and capacity so the laptop reports the same design capacity and run time.

No Extra Parts Included

The package contains only the battery itself; no tools, screws, adhesives or software discs are supplied. Installers must reuse the existing fasteners and any thermal pads or brackets from the old pack.

Straightforward Swap With Care Points

The battery fits the original compartment without modification, but the connector must be aligned before pressing it home. Common issues are forgetting to disconnect the AC adapter first, which can trigger a protection mode, and storing the spare below 80% charge for more than a month, which degrades cell health.

Questions about this item

How often should I replace the KingSener C31N2019 battery to maintain runtime?

Plan on a replacement when the pack no longer holds a useful charge; the 63 Wh Li-ion cells typically last several hundred full cycles before capacity drops noticeably.

What runtime limit appears first during continuous heavy use on this 63 Wh pack?

The 63 Wh capacity is the hard ceiling; once the stored energy is depleted the laptop will shut down or throttle until recharged.

Does the C31N2019 get hot or draw more power when the laptop runs all day?

Normal operation stays within the 11.61 V design envelope; the pack warms slightly under load but does not exceed typical Li-ion thermal limits.
