Replacement Battery for Dell Inspiron

This 4-cell lithium-ion unit replaces the original battery in a wide range of Dell Inspiron 14, 15 and 17 inch notebooks. It is built for owners who need a direct-fit spare to restore mobile operation without modification.

32 Wh Capacity and Daily Runtime

The 2200 mAh pack at 14.8 V delivers 32 Wh of energy, enough for typical office tasks and web browsing on compatible models. Heavier workloads such as video editing or gaming will exhaust the charge more quickly and require a mains connection.

Lithium-Ion Chemistry Limits

The integrated smart chip manages charging current and provides short-circuit, overheat and overload protection during use. Lithium-ion cells gradually lose capacity over repeated cycles, so runtime will decline after extended ownership.

Questions about this item

Will the 14.8V 2200mAh 4-cell pack fit my Dell Inspiron 15(3521) that currently uses a 6-cell battery?

Yes, the 14.8V 4-cell Dr. Battery MPL05283P-25 is listed as compatible with the Inspiron 15(3521); voltage matches and the form factor fits the same bay.

How can I confirm the smart control chip is providing overheat and overload protection after installation?

The battery charges normally, runs without excessive heat, and the laptop reports correct capacity in the OS battery meter; any fault triggers the built-in protection circuit.

Does the box include a Dell 451-12108 part-number label and mounting screws, or must I order them separately?

The replacement battery ships as a complete unit with the correct connector and screw holes; no extra screws or labels are required for installation.
