Battery for VivoBook E12 E203NA E203MA X207NA

This 38Wh lithium-ion replacement battery operates at 7.6V and fits the VivoBook E12, E203NA, E203MA and X207NA series. It replaces part numbers C21N1629, C21Pq91, 2ICP4/59/134, 0B200-02500000 and 00200-02500000M. The black pack is supplied new and ready to install.

Replaces degraded or failed original cells

When the factory battery no longer holds a useful charge or shuts down under load, this unit restores the original runtime. The jump is worth it if the laptop still meets your performance needs and the chassis is intact. It is not for users who need a higher capacity than 38Wh or a different voltage.

Limited to 7.6V 38Wh lithium-ion chemistry

The pack uses the same voltage and capacity as the original specification, so runtime will match the when-new figure rather than extend it. It cannot be used in models that require a different voltage, connector layout or form factor. Compatibility should be verified against the original part number before purchase.

Questions about this item

What physical space does the C21N1629 battery occupy inside the VivoBook E203NA?

The pack is a single black lithium-ion module shaped to the E203NA/E203MA chassis; it slides into the dedicated battery bay and is secured by the original screws.

Which step do installers often miss when fitting the 7.6V 38Wh unit?

After placing the battery, the flexible ribbon cable must be fully seated in its connector before the bottom cover screws are tightened; a loose cable causes a no-power condition.

What replacement will the C21N1629 need after extended daily use?

The lithium-ion cells gradually lose capacity; when run-time drops below your needs, swap in another C21N1629 or compatible 0B200-02500000 pack.
