Direct replacement for Dell Latitude and Precision

This 84Wh lithium-ion battery operates at 11.4V and replaces part numbers WJ5R2, 4F5YV and 31CP7/54/64-2. It fits Latitude 3510 M3510 and Precision 5570 E5570 models. The unit ships new in black.

Simple swap with no tools beyond a screwdriver

Remove the bottom case screws, disconnect the old pack and connect the new one in the same orientation. The connector is keyed, so incorrect insertion is prevented. Most issues arise when screws are over-tightened or the cable is not fully seated.

Capacity fixed at 84Wh and voltage at 11.4V

Runtime scales with the workload of the host system; heavier CPU or GPU loads reduce available hours. The pack cannot be charged beyond its rated capacity and will not fit laptops outside the listed Latitude and Precision series.
