Compatible replacement battery

The 2-Power XCMRD B31N1912 is a 42Wh lithium polymer battery built for ASUS VivoBook 14 and 15.6 inch models including E410, E510, L410, L510 and F414 series. It replaces original part numbers B31N1912 and C31N1912. The unit is new and CE, FCC and RoHS certified.

Thermals noise and power

Lithium polymer chemistry runs cool during normal charging and discharging with no audible noise. The battery operates at 11.55 volts and the matching AC adapter delivers 20 volts at 100 watts. Built-in circuit protection guards against overcharge, over-discharge and short circuits.

Sustained load behaviour

Grade A cells maintain stable voltage through extended work sessions and video playback. The 42 watt hour capacity supports typical office workloads without rapid voltage sag. The pack is designed for repeated daily cycles rather than short bursts.

Questions about this item

How do I install the B31N1912 battery in my ASUS VivoBook, and what step do people often miss?

Remove the bottom cover, disconnect the old battery connector, fit the new 42Wh pack, reconnect it, then replace the cover. The step often missed is disconnecting the old battery before removing it.

What maintenance will this lithium-polymer battery need later?

No scheduled maintenance is required. Capacity will fade with charge cycles; plan to replace the pack when runtime drops below your needs.

What limit appears first during sustained use of this 11.55V battery?

The 42Wh capacity sets the runtime ceiling. Under continuous load the pack will deplete before any thermal or voltage limit is reached.
