It matches the OEM voltage rail and connector pinout for the CELSIUS H230 platform. Capacity is 4400mAh (63.36Wh), consistent with the original Fujitsu specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCELSIUS H230 and FMV-series platform fit:\u003c\/strong\u003e\n    These models share the same 14.4V battery bay, connector layout, and BMS handshake protocol. A single cell specification covers the full range, including FMV-6113NA9\/B, FMV-6120NA, and FMV-830NU\/L variants. OEM part numbers FPCBP88, FPCBP88AP, FPCBP91, FM-43A, FM-43B, FM-44, FM-50, and 0644260 series all reference this same platform battery.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the CELSIUS H230 platform. The BMS handshook correctly with the host system, charge current ramped normally through CC\/CV phases, and the protection circuit tripped cleanly at the low-voltage cutoff threshold without requiring a manual reset.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on the CELSIUS H230:\u003c\/strong\u003e\n    After installing, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after a cell swap. Skip this step and the fuel gauge IC will carry over stale EEPROM data from the old cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting battery health as poor after replacement on the CELSIUS H230\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe CELSIUS H230 BIOS reads health data from EEPROM registers stored in the battery's fuel gauge IC. When a new cell is installed, those registers still reflect the degraded profile of the old battery. The system flags this as poor health or unknown — not because the new cell is faulty, but because the BIOS hasn't yet run a learn cycle against fresh chemistry. One full discharge-to-hibernate followed by an uninterrupted charge to 100% allows the fuel gauge IC to rewrite its EEPROM registers with accurate data for the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCELSIUS H230 shutting down at 20–30% charge shown on the gauge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell voltage drops below the BMS cutoff threshold under combined CPU and display load, even though the OS fuel gauge still reads 20–30%. The fuel gauge IC is calculating remaining capacity from EEPROM data calibrated to the old cell, so the percentage reading lags behind actual cell voltage. Under sustained load, the voltage cliff arrives faster than the gauge predicts, and the BMS cuts power to protect the cell. Run the full discharge-to-hibernate calibration cycle first — after two full cycles the fuel gauge IC recalibrates its voltage-to-capacity curve and the shutdown point aligns with the displayed percentage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410841436250,"sku":"BWCS-FU8300HB-1","price":75.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410841469018,"sku":"BWCS-FU8300HB-2","price":88.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410841501786,"sku":"BWCS-FU8300HB-3","price":98.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FU8300HB-big.webp?v=1779581320","url":"https:\/\/batteryweb.com\/products\/fujitsu-celsius-h230-replacement-battery-144v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
