Replacement for Dell Inspiron series
This 4-cell lithium-ion battery replaces original packs in Dell Inspiron 14, 15 and 17 models including the 3421, 3521 and 5748. It delivers 14.8V and 2200mAh capacity for 32Wh of energy storage. The pack fits the listed part numbers such as X29KD, XRDW2 and 0MF69. It is a new unit built to OEM specification.
Sustained discharge and protection
A built-in smart control chip manages charge and discharge cycles for lower power consumption and longer run time per charge. The circuitry provides short-circuit, overheat and overload protection during continuous use. These safeguards help maintain stable voltage under load and protect both the battery and the laptop.
Voltage and capacity limits
The 14.8V output matches the original design voltage for the compatible Dell models. Capacity is fixed at 2200mAh, giving 32Wh total energy. Users needing higher watt-hour ratings or a different cell count will need a different pack. Verify the original battery voltage and part number before installation.

Questions about this item
Does the 4-cell 14.8V 2200mAh pack run hot or draw extra power when the laptop is under load all day?
The lithium-ion cells are designed to match OEM thermal and power profiles, so heat output and current draw stay within the original Dell specification for the listed Inspiron models.
Which original Dell part numbers must my current battery show for this MPL05283P-24 to be a direct fit?
It replaces Dell part numbers X29KD, XCMRD, XRDW2, YGMTN, 0MF69, 24DRM, 312-1387, 312-1390, 312-1392, 312-1433 and 451-12107.
Will the smart control chip work correctly with the charging circuit in an older Inspiron 14 3421 or 17 5748?
Yes, the built-in chip provides the same short-circuit, overheat and overload protections the original battery uses on every compatible Inspiron 14, 15 and 17 model listed.
