Replacement battery for Asus K501
The Dr. Battery MPL03319P-15 is a new lithium polymer pack rated at 11.4 V and 4200 mAh (48 Wh). It replaces the original Asus B31N1429 cell and matches the listed part numbers including 0B200-01460100. The unit is designed for owners of compatible K501, K501U, K501UX and VivoBook A501 models who need a direct swap.
Thermals noise and power draw in daily use
Lithium polymer chemistry keeps self-discharge low and delivers steady voltage across the discharge curve. The integrated smart control chip manages charging current to reduce heat build-up during recharge and limits power draw once the pack reaches full capacity. No moving parts mean silent operation and no additional acoustic load on the laptop.
Build quality and connector implications
The black housing follows the OEM form factor so it seats in the existing battery bay without modification. Built-in protection circuits guard against short circuit, overheat and overload conditions during everyday charging cycles. A one-year manufacturer warranty covers defects in materials and workmanship. Buyers whose laptops use a different voltage or connector layout cannot use this pack.

Questions about this item
How do I install the MPL03319P-15 in my Asus K501UX and which step is most often missed?
Power off, unplug the charger, remove the bottom case screws, disconnect the old battery cable before lifting it out, then connect the new pack and reassemble; the step most often missed is disconnecting the battery cable first.
What maintenance or replacement will the 11.4V 4200mAh lithium-polymer pack need later?
The pack is sealed and maintenance‑free; after many charge cycles the capacity degrades and the whole unit must be replaced.
What limit appears first during sustained use of this 48Wh replacement battery?
The 4200mAh capacity determines runtime, so the pack will reach its discharge limit and require recharging before any thermal or voltage protection activates.
