It replaces OEM part numbers BAT-SCN07 and 50164357-001. The 8690i is a ring-style wearable terminal used in warehouse pick-and-pack, inventory counting, and asset tracking workflows.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e8690i wearable platform fit:\u003c\/strong\u003e\n    The 8690i uses a compact ring-form housing with a specific connector orientation and BMS handshake tied to Zebra's power management firmware. This pack matches that physical footprint and communicates correctly with the device's fuel gauge circuit.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through rapid scan bursts combined with simultaneous Bluetooth polling loads — the conditions that stress 8690i batteries hardest. The BMS held stable voltage delivery through sustained trigger events without tripping into protection mode.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift charging protocol:\u003c\/strong\u003e\n    After installing, seat the scanner in its cradle and let it complete a full charge cycle before the first shift. The scan trigger inrush current peaks when the cell is near minimum charge, and starting a shift on a partially charged new pack raises the risk of a false BMS protection trip during the first burst sequence.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCradle showing charging error on a new 8690i pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe 8690i cradle communicates with the battery through spring-loaded dock contacts on the underside of the ring unit. Oxidation or debris on either the pack contacts or the cradle pins raises contact resistance enough to trigger a charging fault on the dock's LED indicator. Clean the gold contacts on the battery and the cradle pins with a dry lint-free cloth before reseating. If the error clears and charging begins, the pack itself was never the problem — contact resistance was.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eScanner dropping wireless connection during rapid scan bursts\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 8690i draws simultaneously from the Bluetooth radio and the scan trigger during burst scanning — two inrush loads hitting the cell at once. When a degraded or low battery can't sustain voltage under that combined draw, the radio subsystem drops first because the scanner firmware prioritises the imager. The result looks like a wireless dropout but the root cause is voltage sag at the cell. Charge the pack to full before a high-frequency scanning shift, and check that the cell voltage at rest is above 3.6V before clocking on.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324702818394,"sku":"BWCS-HYR869BL-1","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324702851162,"sku":"BWCS-HYR869BL-2","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324702883930,"sku":"BWCS-HYR869BL-3","price":58.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HYR869BL-1.webp?v=1778122618","url":"https:\/\/batteryweb.com\/products\/zebra-8690i-wearable-rfid-mini-replacement-battery-37v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
