Dr. Battery MPL03249P-08 4-cell 14.4V 2200mAh laptop battery

Direct replacement for Asus laptops

This Dr. Battery MPL03249P-08 is a new 4-cell lithium-ion pack rated at 14.4V and 2200 mAh. It matches the original A41-X550 specification for a wide range of Asus models including R409LC, R510, X450, X550, K450, K550, P450 and P550 series.

Simple swap with built-in safeguards

The battery installs by releasing the latches on the bottom of the laptop and sliding the pack into the bay until it clicks. A smart control chip manages charging current and provides short-circuit, overheat and overload protection. Buyers who skip the model-number check against the original 0B110-00230000 or A41-X550A risk ordering a pack that will not seat or report capacity correctly.

Limited by 4-cell capacity and fixed voltage

The 32 Wh energy rating and 14.4V output are fixed by the cell count and chemistry, so runtime scales directly with the laptop's power draw. Systems that demand higher sustained loads will drain the pack faster than the original higher-capacity options. Users needing all-day mobility without a charger should verify the watt-hour figure against their workload before purchase.
