Compatible replacement for Vivobook S14 S430FA

This lithium-polymer battery carries part number B31N1732 and matches the 11.52V, 42Wh, 3553mAh specification of the original pack. It is intended for owners of the Vivobook S14 S430FA-EB021T and S430UA-EB015T series who need a direct swap. Buyers whose laptops use a different internal battery design or connector layout will not be able to install this unit.

Thermals noise and power in normal use

The cell chemistry and voltage rating are identical to the factory battery, so thermal behaviour and power delivery remain unchanged during typical workloads. No active cooling or fan is present, meaning the component adds no audible noise. Users who require a higher capacity or different voltage for extended runtime cannot meet that need with this replacement.

Installation guidance and charging practice

The supplier notes that connector wire length and physical dimensions may vary even among batteries sharing the same model number, so visual comparison with the original is essential before fitting. Working instructions advise charging with the original adapter, avoiding full discharge below five percent and stopping the charge cycle at ninety-five percent. No additional software, tools or accessories are bundled to alter this procedure.

Questions about this item

How do I install the B31N1732 battery in my Vivobook S14 S430FA-EB021T, and what step is often missed?

Verify the battery matches the product photo exactly — connector shape, wire length and case size can differ even for the same laptop model — then disconnect the old pack and connect the new one.

What maintenance will the 42Wh lithium-polymer pack need later?

Charge with the original adapter, stop at 95 %, recharge at 5 %, and never let it sit at 0 % to preserve cycle life.

What limit appears first during sustained use of the 11.52V 3553mAh cell?

Thermal throttling from the sealed chassis typically caps continuous discharge before the 42Wh capacity is fully drained.
