It fits the DBC835 and DBC835-V2 doorbell camera units. Same cell dimensions at 35.20 × 33.80 × 4.50mm — it seats flush with no modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDBC835 and DBC835-V2 compatibility:\u003c\/strong\u003e\n    Both doorbell revisions share the same battery bay geometry, connector pinout, and 3.7V nominal voltage rail. The BMS handshake is identical across both hardware versions, so the same cell works in either unit without adapters.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the DBC835 charge circuit and confirmed the BMS accepted the cell at first connection, completed a full charge cycle without thermal event, and held voltage within the expected range across motion-trigger current spikes from the IR LEDs and processor combined draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install power cycle on the DBC835:\u003c\/strong\u003e\n    After fitting the new battery, power cycle the camera once through the ADT app. The firmware must re-register the cell before motion events log correctly to cloud storage — skipping this step can cause the first few motion clips to drop silently.\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 ADT app after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSwapping the battery clears the camera's active session token, which the ADT app uses to maintain a persistent connection. The camera comes back online at the hardware level, but the app doesn't automatically re-establish that session. Go into the app, remove the doorbell device from your account, then re-add it using the standard pairing flow. Once re-paired, live view and motion alerts restore fully.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eApp reporting 0% or stuck percentage after installing a fresh cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DBC835 uses a voltage-threshold indicator, not a fuel-gauge IC. When a new cell goes in, the indicator reads the resting voltage and maps it to a charge percentage — but the mapping calibrates fully only after one complete charge-discharge cycle. Let the battery drain to the camera's low-battery alert, then charge it fully without interruption. After that first full cycle, the percentage reading in the app tracks accurately against actual cell voltage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377782227034,"sku":"BWCS-ADD835BT-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377782259802,"sku":"BWCS-ADD835BT-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377782292570,"sku":"BWCS-ADD835BT-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ADD835BT-1.webp?v=1778772242","url":"https:\/\/batteryweb.com\/products\/adt-wireless-hd-doorbell-camera-replacement-battery-37v-580mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
