If it looks the same and had a 2 pin connector it will work. **Q: Will this battery work for a Dell Latitude e7440?** A: Find the battery in your computer. If it has a 2 pin connector and matches the picture it will work. **Q: Will this bios battery work for a Dell Latitude e6510?** A: I don't think so, at least the part numbers seem different. The correct part number for an e6510 is GC02000KH00. Search for that, it is available on Amazon and elsewhere. I believe it is a standard CR2032 battery inside the heat shrink. The wire harness w/connector is the unique part. **Q: Will this work for Dell E6420?** A: Yes I believe it will. The battery is CR2032 and the only issue you could possible run into is that the connector might be different. If that happens just cut the wires and solder them to the old connector. (Be sure to match the colors of the wires, Black to black and red to red.) ## Customer Reviews ### ⭐⭐⭐⭐⭐ D630, yes. *by S***S on February 24, 2026* Worked perfectly in my Dell D630.

All three laptops needed replacement batteries. These batteries worked perfectly. They came fully charged and although the installation in the laptop was difficult due to the design of the laptop, they were the perfect fit and are working well.
