Damaite 4 Cell Li-ion Battery 54Wh 7.4V for Latitude E7440 E7450 E7420

Replacement Battery for Latitude E7440 E7450 E7420

This 54 Wh lithium-ion unit replaces Dell part numbers 34GKR, PFXCR and 451-BBFS across Latitude 14 7000 Series models including E7440, E7450 and E7420. It delivers 7.4 V from a 4 cell pack in a black housing and is sold new with a 12 month warranty. Buyers needing a different voltage or a higher capacity pack cannot use this part.

Practical Limits of the 7.4 V 4 Cell Design

The 54 Wh rating sets the total energy available per charge cycle and the 7.4 V output must match the laptop's native rail exactly. A 4 cell lithium-ion configuration cannot be combined with other packs or adapted to systems expecting a different cell count or voltage. Users requiring extended runtime beyond this capacity or a hot-swappable multi-bay solution will find this battery does not meet those needs.

Build Quality and Daily Connector Implications

The black casing fits the Latitude E7440, E7450 and E7420 battery bay using the original latch mechanism so installation requires no tools. The connector aligns with the motherboard header for the listed Dell part numbers ensuring a secure seat each time. Owners of other Latitude models or non-Dell ultrabooks will find the physical keying and pin-out incompatible with their chassis.
