The FX-8322 is a portable cardiac diagnostic device used in clinical and mobile settings to record and analyze cardiac electrical activity. Voltage and capacity match the OEM specification — OEM part numbers BTE-002 and 510114040.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFX-8322 and FX-8322R compatibility:\u003c\/strong\u003e\n    Both models share the same 14.8V battery rail, connector pinout, and BMS handshake protocol. A single cell works across both variants without modification or adapter.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through full charge and discharge on the FX-8322 platform. The BMS completed its handshake, charge IC accepted the cell, and the device progressed through its power-on sequence without fault flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap startup protocol:\u003c\/strong\u003e\n    After fitting this battery, let the device run its full power-on self-test without interrupting it. The FX-8322 BMS runs a verification pass at boot — cutting power mid-sequence stores a false battery fault that will not clear until the next clean reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not completing boot sequence on new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe FX-8322 runs a BMS verification handshake during boot that checks cell voltage against internal thresholds calibrated for the OEM chemistry. A new cell may sit slightly below those thresholds if it has discharged during transit or storage. The device reads this as a fault and halts the boot sequence before reaching the main ECG interface. Charge the battery fully using the device's own charging circuit, then power on again — a confirmed full charge resolves the handshake failure in most cases.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator stalling below 100% on first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge cycle, the FX-8322 charge IC applies a conservative current limit to an unrecognised cell, which causes the charge indicator to stall between 85–95% and appear not to progress. This is the charge controller's normal response to a new cell — it is not a fault. Allow the charge cycle to complete fully without interrupting it. After one full charge-discharge cycle, the charge IC recalibrates and the indicator will reach 100% on subsequent charges.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381477572698,"sku":"BWCS-FDX832MD-1","price":106.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381477605466,"sku":"BWCS-FDX832MD-2","price":122.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381477638234,"sku":"BWCS-FDX832MD-3","price":134.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FDX832MD-1.webp?v=1778901051","url":"https:\/\/batteryweb.com\/products\/fukuda-denshi-fx-8322-ecg-replacement-battery-148v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
