Direct replacement for Fujitsu 41CP5/57/79

This 64Wh lithium-ion pack carries part numbers FPB0367S and FPCBP596 and matches the original 15.4V specification. It is a new battery intended for owners of compatible Fujitsu laptops who need to restore factory runtime without modifying the chassis or power circuitry.

Steady discharge at rated voltage

The cell chemistry delivers a stable 15.4V output across the 64Wh capacity, so the laptop sees consistent power during long work sessions rather than a rapid voltage sag after a short burst. Rated at 4196mAh, the pack supports extended unplugged use while the onboard protection circuit manages temperature and current limits under sustained load.

Upgrade from depleted or lower-capacity packs

Replaces part numbers 41CP5, 41CP57 and 41CP79, making the swap worthwhile when the original battery no longer holds a useful charge or when a lower-watt-hour unit was fitted at purchase. Buyers who need a higher voltage or a different form factor should look elsewhere, as this unit is built to the exact electrical and mechanical specification of the listed Fujitsu models.

Questions about this item

Does the 64Wh lithium-ion cell run hot or draw extra power during a full day of use?

The 15.4V 64Wh pack is a direct replacement for the original 41CP5/57/79 module and operates within the laptop's normal thermal envelope.

My Fujitsu laptop uses the 41CP5/57/79 part — will this FPB0367S FPCBP596 unit fit without any extra brackets or cables?

Yes, it replaces FPB0367S, FPCBP596 and 41CP5/57/79 exactly and ships as a single battery with the original connector.

If I keep my older Fujitsu charger rated for the 41CP5/57/79 battery, will it charge this 4196mAh pack correctly?

The 15.4V 64Wh cell matches the voltage and capacity spec of the 41CP5/57/79, so the existing charger will charge it normally.
