Dr. Battery MPL05283P-05 laptop battery 4 cell 14.8V 2200mAh 32Wh black

Replacement battery for listed Dell Inspiron models

This Dr. Battery unit is a 4-cell lithium-ion pack rated at 14.8V and 2200mAh, delivering 32Wh of energy. It is built as a direct replacement for a wide range of Dell Inspiron 14, 15 and 17 series laptops including the 3421, 3542, 5521 and 5748 models. Buyers who need a different voltage or a higher capacity pack cannot use this product.

Built-in smart control chip and protection circuits

The integrated chip manages charging to reduce power consumption and extend discharge time while in use. It also provides short-circuit, overheat and overload safeguards that protect both the battery and the laptop during operation. These features are part of the pack itself and require no extra software or driver installation from the user.

Limits of the 4-cell 14.8V form factor

The 32Wh capacity defines the maximum runtime available from this physical size and cell count; it cannot be increased without changing the pack dimensions. Compatibility is restricted to the specific Inspiron models and part numbers listed, so owners of other Dell series or non-Dell laptops will find the pack mechanically or electrically incompatible.
