About this replacement
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.
