Dell 9JRYT 68Wh battery for Latitude and Precision

This 4-cell lithium-ion pack delivers 7.6V and 68Wh of capacity for compatible Dell Latitude 5400, 5500 and Precision 3540 laptops. It replaces part numbers including 09JRYT, 4GVMP, C5GV2, MCV1G, RF7WM, WJDPW and X77XY. The unit is supplied new and ready for installation.

Sustained discharge and thermal behaviour

Lithium-ion chemistry provides stable voltage output across the discharge cycle rather than a sharp drop-off under continuous load. The 4-cell configuration distributes current draw to limit per-cell stress during extended sessions. No active cooling is required as the pack relies on the laptop chassis for heat dissipation.
