Replacement battery for Inspiron models

This 42Wh lithium-ion unit operates at 11.4V and is built as a direct replacement for the Dell WDX0R part. It fits Inspiron 13 5000 series including 5368 and 5378, Inspiron 13 7000 series such as 7368 and 7378, and Inspiron 14 7000 models 7460 and 7472. The black pack restores original runtime without modification.

OEM fit and connector layout

The battery uses the factory connector arrangement so it seats in the existing bay with no adapter cables or soldering. Its lithium-ion chemistry matches the voltage and capacity the system expects, allowing the onboard fuel gauge to report charge levels correctly. Physical dimensions follow the OEM specification for the listed Inspiron 15 5000, 15 7000 and 17 5000 chassis.

Capacity and voltage limits

At 42Wh and 11.4V the pack delivers the same energy envelope as the original cell set, so maximum run time is defined by that rating. It cannot extend usage beyond what the platform's power draw allows, and it will not support systems that require a different voltage or higher watt-hour specification. Compatibility is limited to the part numbers and model series shown above.
