Dell 40 WHr 4-Cell Primary Lithium-Ion Battery

The Dell 453-BBBR is a 40 WHr 4-cell lithium-ion battery made for select Inspiron, Latitude, and Vostro notebooks. It provides a reliable replacement for an original battery that no longer holds a charge, helping users stay productive without being tied to a power outlet.

With a 2700 mAh capacity, the battery supplies consistent power that supports everyday tasks such as browsing, document editing, or video conferencing.
