Direct replacement for Asus K501

This Dr. Battery MPL03319P-16 is a new lithium-polymer laptop battery rated at 11.4 V and 4200 mAh (48 Wh). It matches the original specifications for numerous Asus K501, K501L, K501LB, K501LX, K501U, K501UB, K501UQ, K501UW and K501UX models as well as VivoBook A501C1, A501L and A501LX variants. The pack is designed to fit the same bay and connector as the factory unit.

Sustained output with integrated protection

The built-in smart control chip manages charging and discharging to deliver consistent voltage under continuous load rather than only in short bursts. It provides short-circuit, overheat and overload safeguards that keep the cells operating within safe limits during extended sessions. Lower internal power consumption helps maintain usable runtime across the full discharge cycle.

Verify your exact model

Before ordering, confirm that your laptop appears in the listed compatibility range (K501 / K501L / K501LB / K501LX / K501U / K501UB / K501UQ / K501UW / K501UX and VivoBook A501C1 / A501L / A501LX). Cross-reference the original battery part number 0B200-01460100 / 0B20001460100 / B31N1429 and ensure the voltage reads 11.4 V. This pack will not fit other Asus series or third-party notebooks.

Questions about this item

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

The built-in smart control chip manages charging and discharge to reduce heat and lower power consumption during continuous operation.

What must I already have in the laptop for this 4200 mAh battery to fit and connect?

It replaces Asus batteries such as 0B200-01460100 and B31N1429 in the listed VivoBook A501 and K501 models, so the original battery compartment and connector are required.

Will this 48 Wh replacement work reliably in an older K501LX that still has its original charging circuit?

Yes, the pack is built to OEM specification for the K501 series and includes short-circuit, overheat and overload protections for safe operation with existing hardware.
