Replacement battery for Asus VivoBook S14

This 42Wh lithium-ion cell operates at 11.52V and fits the VivoBook S14 S430FA, S430FN, VX60G, X430FN and related S4300F, S4300FN, X430UN and X430UF models. It replaces part numbers B31N1732, B31Bi9H, 0B200-02960000, 0B200-02960400 and 31CP5/57/80. The pack is supplied new in black.

No bundled accessories or software included

The shipment contains only the battery itself; no tools, screws, adhesive strips or diagnostic utilities are provided. You will reuse the original fixing hardware from the old pack. Without a supplied installation guide you must rely on the laptop service manual for disassembly steps.

Straightforward swap if the service manual is

Removing the bottom case screws and disconnecting the old battery connector is the standard procedure. The most common issue is stripping the small case screws or forgetting to unplug the connector before lifting the board. Take care not to puncture the soft pouch when prying it loose.

Questions about this item

How often will the B31N1732 lithium-ion pack need replacing?

The 42 Wh cell is rated for normal daily cycling; plan on a swap once runtime no longer covers your work session.

What stops the 11.52 V battery from running longer on a single charge?

The 42 Wh capacity is the hard ceiling — when the pack hits empty the laptop must plug in.

Does the 31CP5/57/80 replacement get hot or noisy during all-day use?

It has no moving parts and runs silently; warmth stays at normal laptop-battery levels.
