Replacement Battery for VivoBook 14 and 15

This 42Wh lithium-ion pack operates at 11.55V and uses three cells in a black housing. It is built as a direct replacement for the B31N1912 and C31N1912 original modules. The package includes the battery, two screwdrivers and an instruction sheet. It is intended for owners of compatible Asus VivoBook notebooks who need a new power source.

42Wh Capacity at 11.55V

The 42Wh rating at 11.55V is the single figure that confirms whether this unit matches the original specification. Compatible part numbers include 0B200-03680000 and 0B200-03680100. Supported models cover the VivoBook 14 E410, E410M, E410MA, L410, L410M and L410MA series. The list also extends to VivoBook 14 F414 and F414MA, plus VivoBook 15 E510, E510M, E510KA and L510, L510MA families.

Steady Output Through a Full Workday

Under sustained load the three-cell design delivers a stable 11.55V rail until the stored 42Wh are depleted, avoiding the voltage sag that can trigger early shutdowns on lighter bursts. The chemistry is rated for repeated daily cycles in ultraportable chassis. Buyers who need a higher-watt-hour pack for longer unplugged sessions or a second battery for hot-swap configurations will not be served by this model.

Questions about this item

How long will the 42Wh capacity keep a typical VivoBook 14 running?

A 42Wh pack usually delivers several hours of mixed office work on these 14-inch models; actual time depends on screen brightness, CPU load and battery health.

What voltage does the 11.55V rating require from the laptop?

The battery operates at 11.55V, matching the original B31N1912 specification, so the laptop's charging circuit must accept that nominal voltage.

Does the 3-cell pack fit the same bay as the original battery in an E410MA?

Yes, the 3-cell B31N1912 is a direct mechanical replacement for the factory pack in the E410MA and listed siblings; the kit includes two screwdrivers for the bottom-case screws.
