Replacement battery for Fujitsu LifeBook series

The Cameron & Co DS-CS-FUE551NB is a lithium-polymer battery designed for Fujitsu LifeBook E448, E449, E458, E459, E548, E549 and E558 models. It replaces original part numbers CP721834-01, CP734928-01, FMVNBP247, FMVNBP248 and FPB0338S. The black pack fits directly into the battery bay without modification. It is intended for users who need a new power source for these specific notebooks.

Capacity and runtime headroom

The cell delivers 3.45 Ah of charge, matching the rated capacity of the original equipment battery. It supports typical office workloads such as document editing, web browsing and video playback for a full workday on a single charge. Runtime decreases under sustained heavy loads such as rendering or large dataset processing. The pack is not suited for users who require extended off-grid operation beyond the standard design envelope.

Thermals, noise and power draw

Lithium-polymer chemistry generates minimal heat during normal charge and discharge cycles, so the laptop's existing thermal management handles the battery without extra fan activity. The pack adds no audible noise because it contains no moving parts. Power draw from the system remains within the original specification, so the supplied AC adapter continues to charge the unit at the standard rate.
