Direct replacement for Dell Precision and Latitude

This 11.4 V lithium-ion pack replaces OEM part numbers R8D7N, W8GMW, 49HG8 and TNT6H. It fits Dell Precision 3540, 3541, 3550 and Latitude 5400, 5410, 5500, 5510 models. The three-cell design delivers 51 Wh of energy for compatible systems.

Limited to specific Dell chassis and voltage

The battery only works in the listed Precision, Latitude and Inspiron 2-in-1 models that accept an 11.4 V three-cell pack. It cannot be used in laptops requiring a different voltage, cell count or physical form factor. Compatibility is defined by the exact OEM part numbers above.

51 Wh capacity suits typical mobile workloads

At 4474 mAh the pack provides enough capacity for everyday office tasks and light travel use on supported devices. Runtime will decrease under sustained high-load scenarios such as rendering or gaming. It does not extend to machines needing higher-watt-hour configurations.
