Replacement Battery for Latitude 7000 Series

This 47Wh lithium-polymer pack operates at 7.4V and fits Dell Latitude 14 7000 series ultrabooks including the E7440, E7420 and E7450 models. It replaces a long list of Dell part numbers such as 451-BBFT, 451-BBFV, 451-BBFY, 3RNFD, 34GKR, F38HT, T19VW, PFXCR, G0G2M and 909H5. Grade A cells provide reliable charge cycles and low self-discharge.

For owners of compatible Dell ultrabooks only

The battery suits users whose Latitude 14 7000 unit no longer holds a charge and who can verify their part number against the compatibility list. It is not for owners of other Dell series, different screen sizes or non-Dell laptops. Buyers who need a higher capacity pack or a different voltage should look elsewhere.

Direct swap with built-in protection

Installation requires no extra cables or adapters; the pack slots into the existing battery bay and connects to the motherboard header. On-board circuit protection guards against over-charge, over-discharge and short circuits, freeing the system from external power bricks for mobile use.
