It replaces OEM part numbers 4032-001, 5353, and EE120308. These portable clinical devices use this cell pack for continuous and spot-check SpO₂ and heart rate monitoring in hospital and home settings.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e8600 \/ 8604 \/ 8700 platform compatibility:\u003c\/strong\u003e\n    These models share the same 6V battery rail, connector footprint, and BMS handshake protocol. One cell pack covers the entire platform without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and load on the 8600 platform. The BMS accepted the cell chemistry, completed its internal verification, and reported normal battery status without fault codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After installing this battery, let the oximeter run its full power-on self-test without interruption. The device runs a BMS verification sequence at startup — cutting power during this window triggers a persistent battery fault flag that will not clear until the next complete reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm on the 8600 immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe 8600's BMS uses a voltage threshold calibrated to a fully conditioned OEM cell. A new Ni-CD pack sitting at nominal resting voltage may read slightly below that threshold on the first power-on, triggering the alarm even when the cell is fully charged. This is a BMS learn-cycle issue, not a cell defect. Run one complete charge-discharge-recharge cycle before clinical use. After that first cycle, the BMS recognises the cell's actual voltage curve and the alarm clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice shuts off unexpectedly during patient monitoring in the first week of use\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-CD cells deliver their lowest sustained voltage during the first 8–10 charge cycles before the chemistry fully conditions. The 8600's load profile during continuous SpO₂ monitoring draws harder on the pack than spot-check use, which can push a new, unconditioned cell below the BMS cutoff voltage mid-session. This is a break-in characteristic of Ni-CD chemistry, not a faulty cell. Run the device through five full charge-discharge cycles on the bench before returning it to continuous patient monitoring duty.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381412102234,"sku":"BWCS-SNH613MD-1","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381412135002,"sku":"BWCS-SNH613MD-2","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381412167770,"sku":"BWCS-SNH613MD-3","price":70.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SNH613MD-1.webp?v=1778900625","url":"https:\/\/batteryweb.com\/products\/nonin-8600-replacement-battery-6v-2000mah-ni-cd","provider":"BatteryWeb","version":"1.0","type":"link"}
