Dr. Battery MPL05240P-06 6-cell 10.8V 4400mAh laptop battery

Replacement Battery for Dell Vostro and Inspiron

This 6-cell lithium-ion unit replaces original Dell batteries across the Vostro 1440, 1540, 1550, 2420, 2520, 3450, 3550, 3555 and 3750 lines as well as numerous Inspiron 13R, 14, 14R, 15, 15R, 17R and M-series models. It delivers 10.8V and 4400mAh for direct drop-in compatibility.

Black 6-Cell Pack with Integrated Protection

The black housing contains six lithium-ion cells rated at 48Wh and a built-in smart control chip that manages charging, guards against short circuits, overheating and overload, and extends discharge time. The pack matches the original form factor so it seats securely in the existing battery bay without adapters.

Upgrade from Worn or Lower-Capacity Originals

Owners of the listed Dell notebooks whose factory batteries no longer hold a useful charge gain a new 4400mAh power source backed by a one-year warranty. The jump is worthwhile when the original cell count was six or fewer and the voltage matches 10.8V; systems requiring higher cell counts or different voltages are not served by this pack.
