DELL 47Wh 4-Cell Lithium-Ion Battery 451-BBFT 451-BBFV 451-BBFY 451-BBOG 451-BBFS

47Wh 4-Cell Replacement Battery

This 47Wh lithium-ion pack replaces Dell part numbers 451-BBFT 451-BBFV 451-BBFY 451-BBOG 451-BBFS. It is built for owners of compatible Dell notebooks who need a direct swap when the original cell pack no longer holds a useful charge. The four premium cells deliver 100% compatibility and a perfect mechanical fit. CE and RoHS certification confirms compliance with safety and environmental standards.

Thermals Noise and Power Draw

Lithium-ion chemistry runs cool during typical office or media workloads and adds no audible noise because the pack has no moving parts. The 7.4V nominal voltage matches the laptop's power-management expectations so the system reports capacity accurately. A one-year replacement warranty covers defects in materials or workmanship under normal use.

Installation and Build Impact

The battery slides into the existing bay without tools or cable adapters freeing the user from a tethered power brick. No BIOS update or driver installation is required and the pack works with the original AC adapter. Buyers who need a higher capacity than 47Wh or a different voltage should verify their service tag before ordering.
