Battery, 54WHR, 4 Cell,

The Dell 451-BBJZ is a primary notebook battery that powers the computer when it is away from an AC supply. Dell lists this version with four cells and an energy capacity of 54 Wh.

Dell’s price list shows the exact part number in a Latitude E7450 configuration. This links it to that configuration only; compatibility with other models is not established. As the primary battery, it is intended for the notebook’s main battery position and provides portable power when there is no mains connection.
