Dr. Battery MPL05283P-29 replacement

This 4-cell lithium-ion battery delivers 14.8V and 2200mAh capacity for compatible Dell Inspiron models. It serves owners of listed 13, 14, 15 and 17-inch systems needing a new power source. The 32Wh pack suits daily mobile use on supported devices.

Practical limits of lithium-ion chemistry

Capacity fades with charge cycles and storage temperature extremes. The 2200mAh rating reflects nominal output; run-time varies by laptop workload and power settings. Cells age even when unused, so long shelf storage reduces future performance.

Straightforward swap with verification step

Installation requires removing the old pack and fitting this unit into the same bay. The main risk is ordering the wrong part; match your original battery number and voltage before purchase. A built-in smart chip manages charging and safety protections.

Questions about this item

Should I pick the 14.8V 2200mAh version or look for a higher-capacity option?

This model is a 4-cell lithium-ion pack rated at 14.8V and 2200mAh (32Wh). Choose it when your original battery matches those exact figures; a different capacity would change run time and may not fit.

What does the 2200mAh / 32Wh rating mean for daily use on my Inspiron?

The 32Wh rating indicates the total energy the pack can store. On a typical Inspiron 15 or 17 it delivers several hours of mixed workloads before needing a recharge, depending on screen brightness and CPU load.

Does this battery use a proprietary Dell connector or a standard interface?

It connects through the standard Dell battery bay interface used across the listed Inspiron 14, 15 and 17 models. The built-in smart chip handles charge management and safety protections.
