Replacement battery for Dell Inspiron and Latitude

This 14.8V 40WH unit replaces the original XCMRD pack in a wide range of Dell Inspiron 15, 17 and 14 models as well as Latitude 3440 and 3540 series. It matches the listed part numbers including 49VTP, T1G4M and 312-1390 so owners can swap the old cell without adapter changes. The product is new and ready for immediate installation.

Lithium-ion pack with direct-fit connector

The battery uses the same form factor and connector layout as the factory unit, so it seats in the existing bay and locks with the original latches. No extra cables or mounting brackets are required and the 14.8V output aligns with the laptop's charging circuit. The 40WH capacity restores the runtime the system was designed for.

Limited to models using the XCMRD 14.8V 40WH

This pack will not fit Dell laptops that require a different voltage, capacity or physical profile such as newer Inspiron 3000 revisions or ultrabook chassis. Buyers who need a higher-watt-hour option or a battery for a non-listed part number must look elsewhere. Compatibility is strictly defined by the supplied part-number list.
