Replacement Battery for VivoBook S14 and X411

This lithium-polymer battery replaces the original B31N1707 pack in compatible ASUS VivoBook S14 and X411 notebooks. It is built for owners whose factory cell no longer holds a useful charge. Buyers who need a different voltage or physical layout cannot use this part.

Sustained Load Behaviour

The two-cell design delivers 11.52 volts and 42 watt-hours of energy for steady operation during typical work sessions. Capacity remains consistent across the discharge cycle rather than dropping sharply after a brief peak. Systems that demand higher continuous current than this pack provides will not run correctly.

Deciding Specification

The critical match is the 11.52V 42Wh 3653mAh rating combined with the exact B31N1707 form factor. Verify the original battery photo and part number before ordering because identical laptop models may use different internal packs. A mismatch in connector shape or wire length will prevent installation.

Questions about this item

How much heat does the 11.52V 42Wh battery generate during all-day use?

Lithium polymer cells in this 2-cell pack run cool under normal loads; the 42Wh capacity means modest current draw, so warmth stays low even after hours of continuous operation.

What existing charger must I already own to recharge this B31N1707 pack?

Use the original ASUS charger that came with your VivoBook S14 or X411 series notebook; the battery accepts the same 11.52V input from that adapter.

Will this 3653mAh replacement fit alongside the original motherboard and cooling assembly in a VivoBook S410UA?

Yes, the B31N1707 matches the factory form factor and connector for S410UA models; verify the photo matches your old battery before installing.
