Replacement battery for Inspiron 14z and 15z

This 11.1V lithium-ion pack delivers 44Wh of capacity in a black housing. It is built to fit Inspiron 14z-5423 and 15z-5523 series notebooks. The cell chemistry matches the original specification for direct replacement use. Buyers with other Dell models should verify the part number before ordering.

Replaces part numbers 2NJNF TPMCF T41M0 8JVDG

The unit substitutes the factory battery when the original no longer holds a useful charge. Swapping is worthwhile when runtime has dropped below daily needs or the system shuts down unexpectedly. It is not intended for users who need a higher-capacity pack than 44Wh or a different voltage. The 12-month warranty period covers defects in materials and workmanship.

Limited to 11.1V 44Wh lithium-ion form factor

The pack fits only the listed Inspiron 14z and 15z chassis and the electrical interface defined by the original part numbers. It cannot be used in laptops that require a different voltage, connector layout or physical dimensions. Capacity is fixed at 44Wh and cannot be expanded by this module alone. Users needing longer runtime must consider external power solutions.

Questions about this item

Will the 44Wh 11.1V pack fit the battery bay of an Inspiron 14z-5423?

The pack is built to the original dimensions for the Inspiron 14z-5423 and 15z-5523 series, so it seats in the same bay without modification.

What is the correct order to connect the new 2NJNF battery?

Remove the old pack, align the connector on the 2NJNF unit with the motherboard header, press firmly until it clicks, then secure the retaining screws.

When should the 44Wh lithium-ion cell be replaced?

Replace the unit when run-time falls well below the original 44Wh rating or the laptop shuts down unexpectedly under load.
