Replacement battery for Asus K501 and VivoBook A501

This lithium-polymer unit replaces the original B31N1429 pack in Asus K501, K501L, K501LB, K501LX, K501U, K501UB, K501UQ, K501UX, K501UW and VivoBook A501L, A501LX models. It is built for owners whose factory battery no longer holds a useful charge.

Steady 11.4 V output through the full discharge

The 3400 mAh cell delivers a consistent voltage under continuous workloads rather than sagging after a short burst. Integrated protection circuits guard against short circuit, overheat and overload during extended sessions.

Low heat and silent operation in daily use

Lithium-polymer chemistry runs cool without moving parts, so the laptop stays quiet and surface temperatures remain modest. The 39 Wh capacity keeps power draw modest while maintaining run time for typical office tasks.

Questions about this item

Does the 11.4 V lithium-polymer pack run hot or draw extra power during all-day use?

The battery includes short-circuit, overheat and overload protections, and its 39 Wh capacity is designed to match the original thermal profile of the Asus K501 and VivoBook A501 series.

You need an Asus K501, K501L, K501LB, K501LX, K501U, K501UB, K501UQ, K501UX, K501UW or VivoBook A501, A501L, A501LX model that originally used a B31N1429 or 0B200-01460100 battery.

Will this 3400 mAh replacement behave the same as the original battery in an older Asus K501UX-AH71?

Yes, the voltage, capacity and cell chemistry match the factory B31N1429 specification, so charge reporting and runtime remain unchanged on supported K501 and VivoBook models.
