It slots into the same battery bay and connects via the same contacts as the factory pack. Capacity is 6400mAh (23.68Wh) — pulled directly from product data, not estimated.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDoorbell 2, 3 Plus, and Spotlight Cam compatibility:\u003c\/strong\u003e\n    These models share the same removable battery bay format, contact orientation, and 3.7V nominal voltage rail. The BMS on each platform expects the same charge termination voltage, so the same cell works across all three without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this battery through charge and discharge cycles on the Video Doorbell 2 platform. The BMS accepted the cell without fault codes, motion recording initialised correctly, and voltage held steady under the combined draw of the IR LEDs and processor during night-vision events.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install firmware registration:\u003c\/strong\u003e\n    Power cycle the doorbell once through the Ring app after installing this battery. The firmware must register the new cell before motion events log correctly to cloud storage — skip this step and motion clips may fail to save even though the camera appears live in the app.\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 Ring app after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSwapping the battery interrupts power to the doorbell's WiFi module, which drops the active session token the Ring server holds for that device. The camera comes back online at the hardware level, but the app may still show it as offline or unresponsive. This is not a battery fault — it is a session re-registration issue. Open the Ring app, go to Device Health, and trigger a reconnect or remove-and-re-add the device to force a fresh handshake.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eApp reporting 0% or incorrect charge percentage after install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Ring Doorbell 2 uses a voltage-threshold indicator, not a fuel gauge IC. When a new cell is installed at partial charge, the firmware maps the resting voltage to a percentage — and if that voltage sits between thresholds, the reading can show 0% or jump unexpectedly. Run the battery down until the device gives a low-battery alert, then charge it fully to 4.2V. One complete cycle recalibrates the threshold map and the percentage display will track correctly after that.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377785471066,"sku":"BWCS-RDL200XL-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377785503834,"sku":"BWCS-RDL200XL-2","price":44.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377785536602,"sku":"BWCS-RDL200XL-3","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RDL200XL-1.webp?v=1778772259","url":"https:\/\/batteryweb.com\/products\/ring-video-doorbell-2-replacement-battery-37v-6400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
