Dell 51Wh 3-Cell Lithium-Ion Battery

This 51Wh lithium-ion battery supplies 11.4V power to compatible Dell laptops. It uses three premium-quality cells and carries CE and RoHS certification for safety and environmental compliance. The unit is sold new and includes a one-year replacement warranty.

Replaces Worn Dell 266J9 0415CG Series Batteries

The pack fits Dell part numbers 266J9, 0415CG, C9VNH, 0PN1VN and 0M4GWP, restoring original runtime when the old cell no longer holds charge. Two different batteries exist for some Dell models and they are not interchangeable, so the jump is worth it only after confirming the original matches the product photos.

Suits Owners of Listed Dell Notebooks Needing

Buyers who cannot verify their original battery against the supplied images should look elsewhere, as fitment is not universal across all Dell chassis. The pack is also unsuitable for anyone requiring a higher-wattage or different-voltage power source than the specified 51Wh at 11.4V.

Questions about this item

Does the 51Wh 3-cell pack fit my Dell without changing brackets?

The 11.4V lithium-ion pack is built to the original Dell dimensions for part numbers 266J9, 0415CG, C9VNH, 0PN1VN and 0M4GWP, so it slides into the existing bay with no bracket changes.

What is the step people miss when swapping this battery?

After inserting the new pack, boot the laptop and let the firmware calibrate the fuel gauge by running a full charge and discharge cycle before relying on the reported percentage.

When will the 51Wh lithium-ion pack need replacing?

Capacity fades with each cycle; plan a replacement when run-time falls to roughly half of the original 51Wh or the battery no longer holds a useful charge for your workload.
