Compatible Dell models

This 4.4 Ah lithium-ion battery fits Dell Inspiron 14R-346, 14V, 14VR, M4010, M4010-346, M4050, N4020, N4030 and N4030D laptops. It replaces original part numbers including 312-1231, FMHC10, KG9KY, TKV2V, W4FYY and X3X3X. The pack is supplied new and black.

Sustained runtime behaviour

Rated at 11.1 V and 4400 mAh, the cell pack delivers 48.84 Wh of energy for typical mixed workloads. Capacity holds steady across normal charge cycles without the sharp drop-off seen in aged original units. It is not designed for users who need extended off-grid sessions beyond a single charge.

Thermals and power draw

The slim 208.20 x 62.00 x 21.40 mm form factor fits the original bay without forcing the chassis. Lithium-ion chemistry runs cool during regular office use and produces no audible noise. Buyers needing hot-swap capability or a second bay adapter will not find that support here.
