It fits the Circle 2 indoor and outdoor variants, including models listed as ICES-3(3), NMB-3(B), and V-U0045. Swap it in when the original cell can no longer hold charge or causes the camera to shut down unexpectedly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCircle 2 wire-free platform:\u003c\/strong\u003e\n    All Circle 2 wire-free variants share the same 3.7V cell format, connector pinout, and BMS handshake. That common hardware base means this cell works across the indoor, outdoor, and wire-free configurations without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the Circle 2 platform. The BMS accepted the cell cleanly, voltage stayed within spec across the charge curve, and the camera's motion recording triggered correctly under load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install power cycle:\u003c\/strong\u003e\n    After fitting the new cell, power cycle the camera once through the Logitech app. The firmware must register the new cell before motion events log correctly to cloud storage — skipping this step can cause missed recordings on the first night.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamera going offline in the app after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eReplacing the battery in the Circle 2 can drop the camera's active session token, which the Logitech app uses to maintain a live connection. When the token is lost, the app shows the camera as offline even though the cell is fully charged and the hardware is functioning. This is a firmware-side issue, not a battery fault. Remove the camera from the app and re-add it through the standard setup flow to re-register the device and restore the connection.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eApp reporting 0% or an incorrect charge level after install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Circle 2 uses a voltage-threshold indicator rather than a fuel gauge IC — it reads the cell voltage and maps it to a percentage using fixed reference points. A new cell at rest voltage can fall between thresholds, causing the app to display 0% or an obviously wrong figure. This is not a faulty cell. Run one full charge cycle from flat to 4.2V and the indicator will calibrate its reading to the correct threshold band.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377786781786,"sku":"BWCS-LCE200SL-1","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377786814554,"sku":"BWCS-LCE200SL-2","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377786847322,"sku":"BWCS-LCE200SL-3","price":41.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LCE200SL-1.webp?v=1778772243","url":"https:\/\/batteryweb.com\/products\/logitech-circle-2-replacement-battery-37v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
