70Wh lithium-ion replacement battery

This 11.61V lithium-ion pack replaces the original C31N2105 cell in a wide range of Vivobook S, Vivobook X and Vivobook 14X, 15X and 16X models. It fits machines identified by part numbers 0B200-04140000 and 31CP6/70/81. The black unit ships new and carries a twelve-month warranty.

Steady output through a full workday

Rated at 70Wh, the battery delivers consistent voltage across extended sessions rather than only brief peaks. Lithium-ion chemistry maintains stable discharge under sustained loads such as video playback, compilation or light creative work. Capacity remains predictable from the first cycle through the warranty period.

Direct swap for worn or failed originals

The pack restores runtime to notebooks whose factory cells have degraded below usable levels. It is not intended for users who need a higher-capacity upgrade beyond the original 70Wh specification. Buyers requiring longer unplugged time should look for an extended-capacity alternative if one exists for their chassis.

Questions about this item

How much heat does the 70Wh 11.61V lithium-ion battery generate during all-day use?

Lithium-ion cells run cool under normal load; the pack produces only gentle warmth that the laptop chassis dissipates without extra fan noise.

What must already be in the laptop for this C31N2105 pack to work?

The laptop must use the original 11.61V 70Wh form factor and connector — models such as Vivobook 14X OLED X1403ZA or Vivobook S 15 K3502ZA already have the matching bay and wiring.

Will the 0B200-04140000 replacement fit a Vivobook 16X M1603QA that originally shipped with a 31CP6/70/81 cell?

Yes — the part numbers C31N2105, 0B200-04140000 and 31CP6/70/81 are cross-referenced, so the pack slides into the same bay and connects to the existing motherboard header.
