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 FMV-LifeBook B8200 — 7.2V Li-ion Replacement Battery (FMVNBP132)

This 7.2V, 7800mAh Li-ion battery replaces the original pack in the Fujitsu FMV-LifeBook B8200, LifeBook B6000D, LifeBook B6110, and LifeBook B6110D. It matches the OEM voltage rail and connector footprint across all four models. Capacity is 56.16Wh — taken from product data, not estimated.

  • B8200 / B6000D / B6110D platform fit: These four models share the same 7.2V two-cell configuration, identical connector pinout, and the same BMS communication protocol — which is why one pack covers the full group without modification.
  • Bench tested on actual hardware: We ran this pack through full charge and load cycles on the B8200. The BMS negotiated correctly with the system controller, charge acceptance reached rated capacity, and no protection faults triggered under CPU and display load.
  • Post-install calibration on the B8200: After fitting this battery, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to complete against the new cell data and clears the inaccurate health warning that appears on every fresh cell swap.

BIOS reporting poor battery health immediately after fitting the new pack

The B8200 BIOS reads health data from the EEPROM on the battery's BMS board, not from a live capacity measurement. When a new cell arrives with EEPROM values that don't match the system's stored history, the BIOS flags it as degraded before it has run a single cycle. This is not a fault with the replacement cell. Run one full discharge to hibernate-cutoff followed by an uninterrupted charge to 100% — after that cycle, the BIOS recalibrates against the actual cell and the health warning clears.

LifeBook B8200 shutting down at 20–30% charge shown on screen

This happens when the cell voltage drops below the BMS cutoff threshold before the fuel gauge IC reaches zero — a voltage cliff under combined CPU and display load. The fuel gauge was calibrated against the old degraded cell and now reads the new cell inaccurately during the first few cycles. It is not a defective replacement. Complete two full discharge-to-hibernate then charge-to-100% cycles and the fuel gauge IC will recalibrate its voltage-to-percentage curve against the new cell chemistry. Unexpected shutoffs should stop once the gauge tracks the actual cell voltage floor, which sits at approximately 6.0V under load for this pack.

Frequently Asked Questions

The LifeBook B8200 shows the new battery as "0% available (plugged in, charging)" and never moves — what's happening?

The fuel gauge IC on the B8200 is reading EEPROM data from the old cell and hasn't mapped its charge curve to the new pack yet. Let the battery charge uninterrupted to 100% without interrupting the session, then discharge fully to hibernate-cutoff. After one complete cycle the IC recalibrates and the percentage display returns to normal tracking.

System info shows the wrong Wh rating for this battery — it's reporting a much lower number than the 56.16Wh on the listing. Is the battery undersized?

The Wh figure shown in system info is pulled from the EEPROM on the BMS board, which stores the rated value written at manufacture — it does not reflect a live measurement of actual cell capacity. The physical cells in this pack are 56.16Wh. The discrepancy is an EEPROM read difference, not a capacity shortfall. No action is needed; the battery delivers full charge regardless of what the OS reports in that field.

Charge stopped at 80% and the B8200 won't charge further — is the replacement battery faulty?

The B8200 BIOS includes a firmware-controlled charge limit that caps charging at 80% when certain power management settings are active — this is a BIOS function, not a battery fault. Go to the Fujitsu battery utility or BIOS power settings, locate the charge threshold or battery care mode option, and set the maximum charge to 100%. Once that setting is changed, the battery will charge to full capacity on the next cycle.
