Dr. Battery MPL03249P-20 14.4V replacement

This 4-cell lithium-ion battery replaces the original pack in compatible Asus F550, K550, P550 and related series laptops. It delivers 2200 mAh at 14.4 volts for 32 Wh of capacity. The unit is new and built to OEM specification levels. Buyers who need a higher-capacity pack or a different voltage should verify their original part number first.

Thermals noise and power draw

Lithium-ion chemistry keeps self-discharge low during storage and typical daily cycling. The integrated smart control chip manages charge current to reduce heat buildup while powering the notebook. No moving parts mean silent operation in normal use. Overheat, short-circuit and overload protections are built into the pack electronics.

Smart chip and protection features

The onboard control circuit enables quicker charging, lower power consumption and longer discharge time per cycle. Safety functions guard against short circuit, overheat and overload conditions. A one-year warranty covers the replacement pack. Compatibility must be confirmed against the original battery label before installation.

Questions about this item

How do I install the MPL03249P-20 battery in my Asus K550 and what step is often missed?

Power off the laptop, unplug the AC adapter, slide the release latch, insert the 14.4V pack until it clicks, then charge fully before first use; the missed step is the initial full charge.

What replacement will the 4-cell 2200mAh lithium-ion pack need over time?

The sealed 32Wh unit is maintenance-free; when run-time no longer meets your needs, replace the entire battery with another compatible 14.4V pack.

What limit appears first during sustained use of the 14.4V 2200mAh battery?

The 32Wh capacity determines how long the laptop runs per charge; under heavy load the pack will reach its discharge limit sooner than under light use.
