Capacity is 10400mAh (38.48Wh) — the same form factor as the OEM unit. It slots into the camera's battery bay without any wiring or tools.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePro 3, Pro 4, and Go 2 compatibility:\u003c\/strong\u003e\n    These models share the same 3.7V single-cell architecture and identical battery bay dimensions. The connector pinout and BMS handshake protocol are consistent across the platform, so one battery SKU serves all of them without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through the Arlo Pro 3 charge and discharge sequence and monitored BMS cutoff thresholds at both ends. The protection circuit triggered correctly at over-voltage and under-voltage limits, and charge acceptance matched OEM behaviour at the 4.2V ceiling.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install power cycle:\u003c\/strong\u003e\n    After inserting this battery, trigger a full power cycle through the Arlo app before relying on motion recording. The camera's firmware must register the new cell to log motion events correctly to cloud storage — skipping this step can cause the first few triggered clips to fail 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 Arlo app after battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eSwapping the battery interrupts the camera's active session with Arlo's cloud servers. The firmware stores a session token that becomes invalid once power drops to zero. When the new battery restores power, the camera attempts to reconnect using the stale token and fails. Open the Arlo app, navigate to device settings, and force a manual sync or re-registration to push a fresh token and bring the camera back online.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eApp showing 0% or incorrect percentage after battery installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eArlo cameras use a voltage-threshold indicator — not a fuel gauge IC — to estimate remaining capacity. A new battery at partial state of charge may sit at a voltage level the camera misreads as empty or near-empty. This is a calibration gap, not a faulty cell. Run one complete charge cycle from the camera's solar input or USB-C charge port until the indicator reads 100%, then let it discharge under normal use to re-anchor the thresholds correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377783668826,"sku":"BWCS-NAR700SL-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377783701594,"sku":"BWCS-NAR700SL-2","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377783734362,"sku":"BWCS-NAR700SL-3","price":55.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NAR700SL-1.webp?v=1778772243","url":"https:\/\/batteryweb.com\/products\/arlo-pro-3-replacement-battery-37v-10400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
