Direct Replacement for ASUS K501 and A501LX Series

This BFKK B31N1429 battery replaces the original 0B200-01460100 unit in ASUS K501LB, K501LX, K501UB, K501UX, K501UW and Vivobook A501LX models. It delivers 11.4V and 48Wh capacity using three Li-ion cells. A screwdriver set is included for installation.

Upgrade from Depleted or Failing Original Cells

The jump is worth it when the factory pack no longer holds a useful charge or shuts down under load. Grade A cells provide up to 500 recharge cycles over the life of the battery. Certified UL, CE, FCC and RoHS protections guard against short circuit, overheat and overload conditions.

Limited to 3-Cell 11.4V Form Factor

This pack fits only the specific 3-cell 11.4V chassis used by the listed ASUS models. It will not work in laptops that require a different voltage, cell count or physical shape. Buyers needing higher capacity or a different connector must choose another part.
