New arrival
From $86.99 USD $106.99
Shipping calculated at checkout.
Fits Fujitsu LifeBook N6460, N6110, N6470, N6420 — replaces FPCBP104AP, FPCBP161AP, FPCBP104.
Delivers 10.8V at 4400mAh capacity — sustains full CPU and display load across Fujitsu LifeBook N-series mobile workstations.
Connector slides into the bay with a single locking tab; polarity keyed to prevent reverse insertion on all compatible models.
We bench-tested this cell with a full CPU load cycle — the BMS regulated discharge smoothly, no early cutoff or voltage sag.
After installation, fully discharge to sleep mode then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears false health warnings that appear on every cell swap.

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Fujitsu LifeBook N6460 Series — 10.8V Li-ion Replacement Battery (FPCBP104AP)

This is a 10.8V, 4400mAh Li-ion replacement battery for the Fujitsu LifeBook N6460, N6110, N6420, and N6470 notebooks. It replaces OEM part numbers FPCBP104AP, FPCBP161AP, and FPCBP104. Install it when the original cell no longer holds a usable charge or fails to power the laptop off AC.

  • LifeBook N6000-series compatibility: These models share the same 10.8V battery rail, connector pinout, and BMS handshake protocol, which is why one cell covers the N6110, N6420, N6460, and N6470 without modification.
  • Bench tested on actual hardware: We cycled this cell through full charge and discharge on the N6460 platform. The BMS communicated correctly with the BIOS, charge termination triggered at the expected threshold, and no protection flags tripped during load testing.
  • First-cycle calibration on the N6460: After fitting this battery, run one full discharge to the hibernate cutoff point, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after swapping cells in this platform.

BIOS reporting poor battery health immediately after fitting a new cell

The LifeBook BIOS reads health data stored in the battery's EEPROM. When a new cell arrives, that EEPROM data reflects factory state, not the laptop's charge history — the BIOS flags this mismatch as poor health. Running one complete discharge-to-hibernate followed by a full uninterrupted charge writes fresh cycle data to the EEPROM. After one or two full cycles, the health indicator normalises and the warning clears.

Laptop shuts down abruptly at 20–30% charge shown on screen

This is a voltage cliff, not a software bug. When the CPU and display draw full load simultaneously, the cell cannot sustain the voltage the BIOS expects at that state of charge. The system interprets the voltage drop as an empty battery and cuts power instantly. Running two full calibration cycles lets the fuel gauge IC map the actual discharge curve of the new cell. If shutdowns persist after calibration, check that the BIOS charge threshold setting is not artificially capping the cell below 10.8V nominal.

Frequently Asked Questions

My LifeBook N6460 shows the new battery as "0% available (plugged in, charging)" and won't move off zero — what's wrong?

The BIOS is reading stale EEPROM data from the new cell and hasn't yet mapped it to a real state of charge. This is normal on first install for this platform. Leave it charging uninterrupted until the indicator moves — it can take 20–30 minutes before the fuel gauge IC begins reporting a real value. If it stays at 0% after a full charge cycle, reseat the battery and check the connector pins are fully engaged.

Windows reports this battery's capacity as 47Wh but the battery health tools show a different "designed capacity" — is the cell faulty?

It's not faulty. The Wh figure Windows reads comes from the EEPROM on the cell, which stores rated chemistry values from the factory. Third-party health tools calculate Wh differently — some multiply measured voltage by reported mAh, others pull the EEPROM directly. The authoritative spec for this cell is 4400mAh at 10.8V, which equals 47.52Wh. Discrepancies between tools are a reporting difference, not a defect.

The N6460's charge gauge is all over the place — jumps from 60% to 85% and back — after fitting the replacement battery. How do I fix it?

The fuel gauge IC inside the laptop still has calibration data from the old cell. It's applying a worn discharge curve to a fresh cell, so the percentage readings are unreliable. Run two full discharge-to-hibernate cycles followed by uninterrupted charges to 100% each time. This forces the fuel gauge IC to relearn the new cell's actual discharge curve and the readings will stabilise after the second full cycle.
