Direct replacement for Fujitsu LifeBook

The KingSener FPCBP424 is a 10.8V 4170mAh lithium-ion battery built to replace part numbers FPB0307S, FPCBP424 and FMVNBP233. It fits Fujitsu LifeBook AH556, AH77/S and AH77/M series notebooks as well as Stylistic Q736, Q737 and Q775 tablets. The pack is supplied new and carries a one-year warranty from the manufacturer.

Steady voltage across a full work session

The 10.8V nominal output holds stable under continuous load, avoiding the voltage sag that can trigger early shutdowns on older cells. Rated at 4170mAh, the capacity supports extended mobile use without the rapid drop-off seen in degraded original packs. Lithium-ion chemistry maintains consistent discharge characteristics from the first cycle through the warranty period.

Verify the exact part number before ordering

Check the label on your existing battery for FPB0307S, FPCBP424 or FMVNBP233 to confirm compatibility. The pack is not suitable for Fujitsu models outside the listed LifeBook and Stylistic series. Buyers who need a different voltage, capacity or form factor should look for the specific part matched to their device.

Questions about this item

Does the 10.8V 4170mAh battery run hot during all-day use?

The lithium-ion cells are rated at 10.8V and 4170mAh; normal operating temperature stays within typical laptop-battery limits for the LifeBook AH556, AH77/S, AH77/M, Stylistic Q736, Q737 and Q775 series.

What must my laptop already have for this FPCBP424 pack to fit?

Your Fujitsu LifeBook or Stylistic must use one of the original part numbers FPB0307S, FPCBP424 or FMVNBP233; the replacement matches that exact form factor and connector.

Will the FPCBP424 work in an older LifeBook AH556 alongside the original charger?

Yes, the 10.8V 4170mAh pack replaces FPB0307S, FPCBP424 and FMVNBP233 directly, so the existing AC adapter charges it without any change.
