42Wh 4-Cell Battery for Dell WDX0R FC92N 3CRH3

This 42Wh lithium-ion battery replaces Dell part numbers WDX0R, FC92N, YRDD6 and 3CRH3. It supplies 11.4V from four premium cells and carries CE and RoHS certification. The unit is sold new and includes a one-year replacement warranty.

Check part number and physical match before ordering

Dell uses two different batteries for the same laptop family and they are not interchangeable. Compare the part number on your original battery to the WDX0R, FC92N, YRDD6 or 3CRH3 codes listed above. Also verify the connector layout and case shape against the product photos to ensure a proper fit.

Thermals noise and power draw in normal use

Lithium-ion chemistry runs cool and silent because the pack has no moving parts. Under typical workloads the 42Wh capacity delivers consistent voltage with minimal self-heating. Power draw follows the laptop's own management profile, so battery life scales with screen brightness and processor load.

The 42Wh capacity typically provides several hours of mixed office work or media playback on a compatible Dell laptop, though actual runtime varies with screen brightness, workload and system power settings.
