It fits the OXY9 Wave directly, restoring power to the device used for blood oxygen saturation monitoring in clinical and home healthcare settings. Voltage and capacity match the OEM specification listed under part number SCR18650F22-012PTC.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOXY9 Wave platform fit:\u003c\/strong\u003e\n    The OXY9 Wave uses a single-cell 3.6V Li-ion configuration with a BMS that handshakes on voltage and temperature data at startup. This cell matches both the electrical and physical envelope the device expects — same connector orientation, same 18650-format housing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran a full charge-discharge cycle on the OXY9 Wave with this cell installed. The BMS completed its initialisation sequence, accepted the charge without flagging a chemistry mismatch, and held voltage stable across the oximeter's SpO2 sampling load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After installing this cell, allow the OXY9 Wave to complete its power-on self-test without interruption. The device runs a BMS verification routine at startup — cutting power during this sequence triggers a false battery fault that persists until a full reboot clears it.\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 after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe OXY9 Wave runs a multi-stage power-on check that includes a BMS learn step. A new cell arriving from storage may sit at 3.5V or lower — enough to start boot, but below the threshold the device needs to pass its internal verification. The BMS will halt the sequence and flag a low-battery error even though the cell is not depleted. Charge the replacement fully before first installation, then let the boot sequence complete without cycling power.\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 with a new cell, the OXY9 Wave's charge IC applies a conservative current ceiling while it profiles the cell's internal resistance. This is normal behaviour — the indicator can stall at 90–95% for an extended period before the final topping phase begins. Do not interrupt the charge. Let the device complete the full cycle; subsequent charges will reach 100% faster once the IC has profiled the cell. Target a resting voltage of 4.1–4.2V at full charge before clinical use.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381461254234,"sku":"BWCS-BCY900MD-1","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381461287002,"sku":"BWCS-BCY900MD-2","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381461319770,"sku":"BWCS-BCY900MD-3","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BCY900MD-1.webp?v=1778900983","url":"https:\/\/batteryweb.com\/products\/bionet-oximete-oxy9-wave-replacement-battery-36v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
