Battery Care Tips
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
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 LH532 — 10.8V Li-ion Replacement Battery (CP568422-01)
This is a 10.8V, 4400mAh (47.52Wh) lithium-ion battery for the Fujitsu LifeBook LH532 and LH532 AP notebook computers. It replaces OEM part numbers CP568422-01, FMVNBP215, FMVNBP216, FPB0271, FPB0272, FPCBP334, and FPCBP335. The connector, BMS handshake, and physical dimensions match the original bay exactly.
- LH532 and LH532 AP compatibility: Both models share the same battery bay, voltage rail, and BMS communication protocol. One SKU covers both variants — no hardware differences affect fitment between them.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the LH532 platform. The BMS authenticated without errors, and the charge controller accepted the cell at full capacity without triggering fault flags.
- First-install calibration on the LH532: After installing, run one full discharge down to hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears on the first boot after any cell swap.
BIOS reporting poor battery health immediately after fitting a new cell
The LH532 BIOS stores battery health data from the previous cell in non-volatile memory. When a new cell is installed, the BIOS compares live readings against that stored EEPROM data and flags a mismatch as poor health. This is not a fault with the replacement cell — it reflects stale calibration data. Run one complete discharge-to-hibernate and uninterrupted full recharge cycle to let the learn cycle rewrite those stored values.
LifeBook LH532 shutting down at 20–30% charge shown
This happens when the fuel gauge IC has not yet calibrated against the new cell's actual voltage curve. The gauge predicts remaining charge based on the old cell's profile, and when real cell voltage drops under combined CPU and display load, the BMS cuts power before the displayed percentage reaches zero. The fix is not a hardware swap — it is calibration. Discharge fully to hibernate cutoff twice in succession, then charge to 100% each time. After two cycles the gauge IC maps the new curve and the early shutdowns stop.

Frequently Asked Questions
The LH532 BIOS shows the replacement battery as "unknown" or 0% on first boot — is the cell faulty?
No. The BIOS fuel gauge IC reads EEPROM data written by the original cell and flags anything that doesn't match as unknown or empty. The new cell hasn't given the system enough data to re-map yet. Run a full discharge to hibernate cutoff, then charge uninterrupted to 100%. After that first complete cycle the BIOS will recognise the cell and display a real percentage.
Windows is showing the wrong Wh rating in Device Manager after fitting this battery — should it match the 47.52Wh on the listing?
Not always on the first read. Windows pulls the rated Wh figure from the battery's EEPROM, which stores design capacity, not the live measured value. Some cells report a slightly different figure until the fuel gauge IC completes its first calibration cycle against actual charge throughput. Run two full discharge-to-100% cycles and check again — the reported Wh figure will stabilise to match the cell's actual capacity.
The LH532's charge stops at 80% and won't go higher — is this a fault with the replacement cell?
Almost always no. Many Fujitsu BIOS versions include a charge limit setting that caps charging at 80% to reduce cell stress during extended mains use. Check the BIOS under the Power menu for a "Battery Charge Level" or "Eco Charge" option. Disable it or set the threshold to 100%, then reconnect the charger — charging will resume to full.
