Direct replacement battery

This new 24 Wh lithium-ion unit matches the original 10.8 V specification for select Fujitsu LifeBook models. It carries part number FPCBP404 and replaces a long list of OEM codes including FMVNBP228 and FMVNBP229A. The black casing fits the existing battery bay without modification.

Fits existing bay and charger

The cell slides into the standard compartment used by the listed LifeBook A544, E733, E734, E743, E744, E751, E753, E754 and E756 series. No extra cabling, adapter or BIOS update is required. The original AC adapter continues to charge the pack at the normal rate.

For owners of compatible LifeBooks only

Buyers with a matching model number from the supported list can restore full mobile runtime. Anyone using a different Fujitsu series or another brand will find the connector and form factor incompatible. Systems needing a higher-capacity pack should look for an extended-life alternative.
