Replacement battery for Asus laptops
The Dr. Battery MPL03249P-21 is a 4-cell lithium-ion unit rated at 14.4V and 2200 mAh. It is designed as a direct replacement for a wide range of Asus models including the K552EA, P450, R409 and A41-X550 series. Buyers who need a higher capacity pack or a different voltage should look elsewhere.
Build quality and daily use
The black battery housing uses professional-grade cells built to OEM specification levels. A smart control chip manages quicker charging, lower power consumption and longer discharge time while providing short-circuit, overheat and overload protections. The pack installs internally using the laptop's existing latch mechanism.
Practical limits of lithium-ion chemistry
Capacity will gradually decline with charge cycles and calendar age, so runtime shortens over several years of regular use. The 32 Wh energy rating defines the maximum work the pack can deliver between charges. Extreme temperatures accelerate degradation and the protection circuits will shut the battery down if safety thresholds are exceeded.
