Verify the part number on your existing battery

Before ordering, confirm that the original battery carries one of the listed part numbers such as 3RNFD, 451-BBFT, 451-BBFV, 451-BBFY, 451-BBOG, G95J5, 909H5, 5K1GW, PFXCR, F38HT, V8XN3, T19VW or G0G2M. The laptop model must be a Latitude E7440, E7450 or E7420 from the 14 7000 series; other Dell families are not supported.

Built-in protection circuits handle safety

The pack includes overcharge, overdischarge, over-temperature and short-circuit protection on the circuit board. No extra software, drivers or calibration tools are bundled; the battery is recognised by the system firmware once installed. The 30-day refund and 12-month replacement terms are handled by the supplier, not by the hardware itself.
