Compatible Dell Models

This 11.4V 6-cell lithium-ion battery replaces OEM part numbers 7146W, 2K0CK, C76H7 and WD8P8. It fits Dell Latitude 7400 2-in-1, Latitude 9410 and Inspiron 14 7000 (7400) systems. The 78Whr capacity matches the original specification for these devices. Buyers with other Dell models or different voltage requirements cannot use this unit.

Installation and Form Factor

The battery slots directly into the internal bay of the compatible laptops without adapters or cable changes. Its black 6-cell construction occupies the same space as the factory pack, leaving all ports, vents and drive bays accessible. No BIOS update or driver installation is required for the system to recognise the replacement. Systems outside the listed compatibility list will not accept this form factor.

Sustained Operation

Rated at 6842mAh, the pack delivers stable current throughout the discharge cycle with low self-discharge when the machine is idle. Built-in circuit protection guards against over-charge, over-discharge and short-circuit conditions during extended sessions. CE, FCC and RoHS certifications confirm the safety circuitry meets regulatory limits. The 6-month replacement warranty covers defects in materials and workmanship under normal use.
