Replacement battery for ASUS Vivobook Flip 14

This 4-cell lithium-ion battery delivers 7.7V and 39Wh for the ASUS Vivobook Flip 14 J401 and TP401 series. It replaces OEM part numbers C21N1714 and 0B200-02740000. The unit is brand new and tested for stable current and low self-discharge.

Upgrade from a depleted or failing original pack

When the factory battery no longer holds a useful charge, this direct replacement restores the laptop's mobile runtime without modification. The swap is worth it when the original cell shows rapid drain, unexpected shutdowns or physical swelling.

39Wh capacity for everyday workloads

The 5065mAh pack handles typical productivity tasks, web browsing and video playback on the 14-inch convertible. Heavy multi-core workloads or sustained high brightness will deplete the reserve faster, requiring a mains connection for extended sessions.

Questions about this item

Does the C21N1714 fit the Vivobook Flip 14 TP401NA chassis?

Yes — the replacement battery is listed for the TP401NA and other J401 and TP401 variants, so it matches the 14‑inch flip chassis.

What is the common mistake when installing the 0B200‑02740000 pack?

Forgetting to disconnect the internal connector before removing the old pack; the cable must be unplugged first to avoid a short.

When will the 5065 mAh lithium‑ion unit need replacing?

After the pack no longer holds a useful charge — typically when runtime falls well below the original 39 Wh rating.
