NShi FPCBP425 45Wh 14.4V 3150mAh laptop battery

Direct replacement for Fujitsu LifeBook ultrabooks

The NShi FPCBP425 is a 45Wh lithium-ion battery built to replace part numbers FPCBP425, FMVNBP232 and FPB0315S. It fits Fujitsu LifeBook T904, T935, T936 and U745 2-in-1 ultrabook models. The pack delivers 14.4V from four cells rated at 3150mAh. Buyers who need a different voltage, connector layout or higher capacity will not be served by this unit.

Drop-in fit with certified safety

The battery uses the original connector and form factor so it slides into the existing compartment without adapters or case modifications. It carries CE, FCC and RoHS certifications confirming electrical safety and environmental compliance. Grade-A cells and an onboard smart chip manage charge balancing and protect against over-charge, over-discharge and short circuits. Systems that require a proprietary authentication handshake beyond the standard pin-out are not supported.

Steady output through daily cycles

Under sustained workloads the pack maintains a stable 14.4V rail while the smart chip regulates current to keep temperature rise modest. The 45Wh capacity is rated for full discharge-recharge cycles; the manufacturer recommends cycling to 5% then fully charging three to four times on first use and repeating a full cycle every other month to preserve longevity. Continuous AC connection without regular discharge cycles will degrade usable capacity faster than normal use.
