7.4V 51Wh Lithium-Ion Dell Battery

This 7.4V lithium-ion battery delivers 51Wh capacity across four premium cells. It is built as a direct replacement for specific Dell notebooks listed in the compatibility data. The pack is new and carries CE and RoHS certification for safety and environmental compliance.

Who This Suits and Who It Does Not

Owners of Dell laptops requiring the exact 0WYJC2, 451-BBLK, 451-BBLN, 8V5GX, F5WW5, WYJC2 or 1KY05 part number will find a correct fit. Buyers whose original battery differs from the product photos or carries a different part number should look elsewhere, as two incompatible variants exist for some models.

7.4V Voltage and 51Wh Capacity Decide Fit

The single specification that determines compatibility is the 7.4V voltage paired with the 51Wh capacity. Only systems designed for this exact electrical profile will operate correctly with this four-cell pack. Verify the original battery matches these figures before ordering.

Questions about this item

Which Dell part numbers must my laptop already use for this 451-BBLK battery to fit?

It replaces Dell 0WYJC2, 451-BBLK, 451-BBLN, 8V5GX, F5WW5, WYJC2 and 1KY05; match your original battery to the photos because two different packs exist for the same notebook.

Will the 7.4 V output work with the charging circuit in my older Dell notebook?

The pack is rated at 7.4 V, matching the voltage required by compatible Dell models, so the existing charging circuit will recognise and charge it normally.

How can I confirm the 4-cell 51 Wh pack is charging correctly after installation?

The battery icon should show a rising charge percentage and the BIOS or Dell Power Manager will report the design capacity of 51 Wh once the first full cycle completes.
