Replacement Battery for VivoBook Flip 14

The KingSener B31N1911 is a 42WH lithium-ion battery built to replace the original pack in compatible ASUS VivoBook Flip 14 and related 14-inch notebooks. It delivers 11.55V from cells assembled in China and weighs 160g. The black housing matches the OEM colour scheme.

42WH Capacity Fit

This unit suits owners of listed models such as the TM420IA, TP470EA, M413DA series and X421DA through X421FQ who need a direct 100% new replacement. Buyers whose laptops require a different voltage, a higher watt-hour rating or a physically distinct pack should look elsewhere.

11.55V Voltage Match

The single specification that decides compatibility is the 11.55V output combined with the 42WH capacity. Only systems designed for this exact voltage and the B31N1911 or C31N1911 part number will operate correctly with this battery.
