It replaces OEM part numbers BTE-002 and 510114040. The battery powers the portable ECG unit during cardiac recording sessions in clinical environments.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFX-8322 and FX-8322R platform:\u003c\/strong\u003e\n    Both models run the same 14.8V four-cell series configuration with an identical connector and BMS handshake protocol. The same battery serves both variants without modification.\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 cell verification handshake on first connection, and the charge IC accepted the cells without fault flags on the first charge cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After installing this battery, do not interrupt the FX-8322's power-on sequence. The device runs a BMS verification step at startup. Cutting power during this window registers a battery fault that persists until the next clean reboot, even if the battery is fully charged.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFX-8322 not completing boot sequence on a new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe FX-8322 runs a startup self-test that includes a BMS communication check. A replacement cell that has not yet completed one full charge cycle may report a state-of-charge value that falls below the device's internal boot threshold. The unit halts the boot sequence and displays a battery fault rather than reaching the home screen. Charge the battery to 100% using the device's own charger before the first power-on, then allow the full boot sequence to complete without interruption.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm triggers immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the FX-8322's battery monitoring circuit compares the cell's reported capacity against a stored OEM baseline. A new replacement cell has not yet completed a learn cycle, so the BMS underestimates actual charge and trips the low-battery alarm early. Run one complete charge-to-discharge cycle before clinical use. After that cycle, the BMS recalibrates its capacity estimate and the alarm threshold aligns correctly with actual cell state.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381477671002,"sku":"BWCS-FDX832MX-1","price":121.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381477703770,"sku":"BWCS-FDX832MX-2","price":141.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381477736538,"sku":"BWCS-FDX832MX-3","price":155.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FDX832MX-1.webp?v=1778901051","url":"https:\/\/batteryweb.com\/products\/fukuda-denshi-fx-8322-ecg-replacement-battery-148v-6800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
