It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

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 N6000 Series — 14.8V Li-ion Replacement Battery (FPCBP105)

This is a 14.8V, 6600mAh (97.68Wh) lithium-ion battery for the Fujitsu LifeBook N6000 series notebooks. It replaces OEM part numbers FPCBP105, FPCBP105AP, FPCBP92, and FPCBP92AP. Confirmed fit across the LifeBook N6000, N6010, N6200, and N6210.

  • N6000 series platform compatibility: The N6000, N6010, N6200, and N6210 share the same 14.8V battery rail, connector pinout, and BMS communication protocol — that is why a single cell covers all four models. Swapping between these variants does not require a firmware change or BIOS update.
  • Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on the N6000 platform. The BMS handshake completed correctly, the fuel gauge IC recognised the cell, and the charge controller stepped through pre-charge, constant-current, and constant-voltage phases without fault flags.
  • Post-install calibration on the N6000: After fitting this cell, run a full discharge to hibernate-cutoff, then charge uninterrupted to 100% without using the laptop mid-cycle. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on this platform.

BIOS reporting poor battery health immediately after fitting a new cell

The LifeBook N6000 BIOS reads health data stored in the original cell's EEPROM. When a new cell goes in, that EEPROM data is blank or mismatched, so the BIOS flags the battery as degraded before it has ever cycled. This is not a fault with the replacement cell. Run the battery learn cycle — full discharge to hibernate, then an uninterrupted charge to 100% — twice in succession. After two complete cycles the BIOS recalibrates against the new cell's actual capacity and the health warning clears.

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

This is a voltage cliff symptom, not a calibration issue. Under combined CPU and display load, the cell voltage drops faster than the fuel gauge IC can track, and the protection circuit cuts power before the displayed percentage reaches zero. It most commonly appears on aged cells, but can also appear on a new cell that has not completed a learn cycle. Run a full discharge to hibernate-cutoff — do not force-shutdown early — then charge to 100% without interruption. If the shutdowns continue after two calibration cycles, check that the charge voltage at the connector is reaching 16.8V, which is the correct end-of-charge target for a 14.8V four-cell Li-ion pack.

Frequently Asked Questions

The LifeBook N6000 fuel gauge is jumping around wildly — it showed 60% then dropped to 12% in ten minutes. Is the new battery faulty?

The fuel gauge IC calibrates itself against charge and discharge data it collects over time. After a cell swap, it has no history for the new cell, so the percentage readings are unreliable for the first few cycles. Run two complete discharge-to-hibernate then charge-to-100% cycles without interrupting either. After the second cycle the fuel gauge IC has enough data points to track the new cell accurately and the erratic readings stop.

Windows Device Manager shows the battery capacity as 57Wh but the cell is rated 97.68Wh — did I receive the wrong battery?

The Wh value Windows reads comes from the EEPROM on the old cell's circuit board, not from the new cell's actual chemistry. The system reports the last value stored in firmware until a full learn cycle writes new data. Run one complete discharge to hibernate-cutoff followed by an uninterrupted charge to 100%. After that cycle Windows will read the correct 97.68Wh figure from the updated fuel gauge register.

The N6000 charges the new battery to 80% then stops — the charging indicator light goes off and nothing happens.

Some LifeBook BIOS versions include a charge-limit setting that caps charging at 80% to reduce cell wear during long AC-connected use. This is a firmware control, not a battery fault. Enter the BIOS setup utility (F2 at POST), navigate to the Power Management section, and disable the battery charge limit or set the threshold to 100%. Save and exit — the battery will then charge to its full 16.8V end-of-charge voltage.
