Capacity is 13400mAh (49.58Wh) — higher than the stock cell. It uses the same OEM form factor and connector so it installs without modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePro 3, Pro 4, Go 2, and FB1001 compatibility:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, connector pinout, and BMS handshake protocol. A single cell works across all of them because Arlo standardised the voltage rail and communication lines from the Pro 3 generation forward.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell in a Pro 3 unit and cycled it through motion-trigger events and night vision sequences. The BMS held voltage under sustained IR LED draw and responded correctly to the camera's charge management circuit without false low-battery flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install power cycle:\u003c\/strong\u003e\n    After fitting this battery, remove and reinsert it once, then open the Arlo app and trigger a manual restart of the camera. The firmware must register the new cell before motion-recording events log correctly to cloud storage — skipping this step can cause the first few clips to drop.\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  \u003cp class=\"bpw-desc-p\"\u003eWhen you pull the original battery, the camera loses power and its active session token with the Arlo cloud expires. The camera comes back online at the hardware level but the app still shows it as offline because the firmware hasn't re-registered the session. This is not a battery fault. Open the Arlo app, go to Camera Settings, and use the Restart option to force a fresh cloud handshake. The camera should appear online within 60 seconds of the restart completing.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eApp reporting 0% or an incorrect charge percentage after install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Arlo Pro 3 uses a voltage-threshold indicator — not a fuel-gauge IC — to estimate charge level. When a new cell goes in at a voltage the camera hasn't calibrated against, the percentage readout can stick at 0% or jump to an implausible number. Run one full charge cycle through the base station or USB-C port until the app confirms 100%, then allow the camera to draw the cell down through normal use. After that single cycle the voltage thresholds align and the percentage tracks accurately. If the readout stays wrong after two full cycles, check that the battery contacts are clean and seated flush.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377783308378,"sku":"BWCS-NAR700XL-1","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377783341146,"sku":"BWCS-NAR700XL-2","price":62.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377783373914,"sku":"BWCS-NAR700XL-3","price":69.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NAR700XL-1.webp?v=1778772243","url":"https:\/\/batteryweb.com\/products\/arlo-pro-3-replacement-battery-37v-13400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
