This Dr. Battery MPL05222P-07 is a new 6-cell lithium-ion pack rated at 11.1V and 4400 mAh. It serves as a direct replacement for Dell Latitude E6400, E6410, E6500, E6510, E8400 and Precision M2400, M4400, M4500 mobile workstations. The grey housing matches the original form factor for these compatible models.

Verify Original Part Number and Voltage

Before ordering, remove the existing battery and confirm its part number against the supported list such as 312-0748, 312-0749, 312-0753, 312-0754, 312-0910, 312-0917 or 312-7414. Ensure the original label also shows an 11.1V output to match this unit's specification. Mismatched voltage or connector layout will prevent proper fit and function.

Integrated Protection and 49Wh Capacity

A built-in smart control chip manages charging current, discharge rate and safety cut-offs for short circuit, overheat and overload conditions. The 49Wh energy rating delivers typical runtime for daily office workloads on the supported Latitude and Precision chassis. Normal operation stays within the thermal envelope of the original design without added fan noise or external power draw.
