Replacement battery for ZenBook UX430 series

This 50Wh lithium-ion pack replaces the original C31N1620 cell in Asus ZenBook UX430, UX430UA, UX430UN, UX430UQ, U4100UQ and ZenBook Pro PU404 models. It matches the 11.55V specification and fits the same bay without modification. The black housing aligns with the factory finish. Buyers needing a higher-capacity alternative will not find one here.

Thermal and power behaviour in daily use

The 50Wh capacity supports typical office workloads and web browsing for several hours on a single charge. Lithium-ion chemistry keeps self-discharge low during standby. No active cooling is required because the cell operates at the same voltage and current profile as the original part.

Sustained-load characteristics

Under continuous load such as video playback or compilation the pack delivers steady current until the controller triggers its low-voltage cutoff. The 12-month warranty period reflects the expected cycle life under normal charge and discharge patterns. Heavy daily cycling will reduce usable capacity faster than light use.

Questions about this item

How is the C31N1620 battery installed in a ZenBook UX430 and what step is often missed?

Remove the bottom case screws, disconnect the old battery connector before lifting it out, then connect the new 11.55V pack and secure it; the step often missed is disconnecting the connector first, which can damage the motherboard.

What maintenance or replacement will the 3ICP5/70/81 pack need over time?

The Li-ion cells lose capacity with each charge cycle; when runtime no longer meets your needs the 50Wh unit must be replaced as it is not user-serviceable.

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

The 50Wh capacity sets the runtime ceiling; under continuous load the pack will reach its discharge limit before any thermal throttle engages.
