Replacement battery for Dell Inspiron

This 6-cell lithium-ion unit delivers 4400 mAh at 11.1 V and replaces a wide range of Dell Inspiron 14, 15 and 17 models from the 3421 through 5748 series. It is built for owners who need a direct swap to restore mobile runtime on a compatible notebook.

Verify model and voltage before ordering

Check the label on your original battery for the exact part number — examples include 24DRM, 312-1387, 312-1390, 312-1392, 312-1433, 451-12107, 451-12108, 49VTP, 4DMNG, 4WY7C, G019Y, MR90Y and V8VNT — and confirm the output voltage reads 11.1 V. The pack will not fit or function correctly on systems outside the listed Inspiron families or on Dell Latitude models that share similar chassis codes.

Thermal behaviour and power profile

The integrated smart control chip manages charge current to limit heat build-up during replenishment and provides short-circuit, overheat and overload safeguards. In normal office use the pack runs cool and silent, drawing power only when the laptop requests it, and the 49 Wh capacity supports typical productivity workloads without excessive temperature rise.
