It fits the AVD1001-100NAR and Smart Doorbell HD Video Wired variants. When mains power drops, this cell keeps the doorbell functional during the interruption.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAVD1001-100NAR and Smart Doorbell HD Video Wired compatibility:\u003c\/strong\u003e\n    Both models share the same backup cell housing, connector pitch, and BMS handshake voltage — this PTC362549 replacement slots into either unit without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through simulated power interruptions and confirmed the BMS negotiated correctly with the doorbell's charging circuit, accepting charge without error flags at 4.2V cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install power cycle:\u003c\/strong\u003e\n    After fitting the new cell, power cycle the doorbell once through the Arlo app. The firmware needs to register the new cell before motion events log reliably to cloud storage.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Arlo Wired Doorbell goes offline in the app after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eReplacing the backup cell can interrupt the doorbell's session token with the Arlo cloud. The device loses its authenticated state during the power-down, so the app shows it as offline even after power returns. This is not a cell fault. Remove the doorbell from your account in the Arlo app, then re-add it as a new device to restore the connection.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eApp reporting 0% or incorrect charge percentage after installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Arlo doorbell uses a voltage-threshold indicator — not a fuel gauge IC — to estimate cell charge. A freshly installed cell at an unfamiliar resting voltage can confuse that threshold map and display 0% or a wildly wrong figure. Run one complete charge cycle through the doorbell's own charging circuit until the mains LED confirms full charge. The percentage reading corrects itself once the cell reaches the 4.2V upper threshold and the firmware re-anchors its reference points.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377773838426,"sku":"BWCS-NAR100SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377773871194,"sku":"BWCS-NAR100SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377773903962,"sku":"BWCS-NAR100SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NAR100SL-1.webp?v=1778772243","url":"https:\/\/batteryweb.com\/products\/arlo-wired-video-doorbell-replacement-battery-37v-400mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
