It slots into the same battery bay and connects through the same contacts as the OEM cell. Capacity figure is from the product specification — not extrapolated from runtime claims.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eArlo Pro 3 \/ Pro 4 \/ Go 2 platform fit:\u003c\/strong\u003e\n    These models share the same battery form factor, contact pin layout, and BMS handshake protocol — the camera firmware reads cell voltage over the same two-wire interface across all listed variants, so one replacement cell covers the full compatibility group.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the Arlo BMS charge sequence and confirmed the protection circuit responds correctly to charge cutoff at full voltage and triggers low-voltage disconnect before the cell reaches damaging depth of discharge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install power cycle via the Arlo app:\u003c\/strong\u003e\n    After fitting the new cell, remove and re-add the camera in the Arlo app rather than relying on a simple reboot. The firmware must register the replacement cell in a fresh session before motion-triggered recording logs correctly to cloud storage — skipping this step can cause missed clips even when the battery indicator reads full.\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\"\u003eSwapping the battery interrupts the camera's active cloud session. When power is restored, the camera attempts to re-authenticate using a cached session token that the Arlo server has already expired. This leaves the camera in a connected-but-unregistered state — online on your network, but shown as offline or unreachable in the app. Remove the device from the app and re-add it through the device setup flow to force a fresh token handshake and restore full remote access.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eApp reporting 0% or incorrect percentage after a new cell installs\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eArlo cameras use a voltage-threshold indicator — not a fuel gauge IC — to estimate charge level. When a new cell first connects, the firmware maps its resting voltage against fixed threshold steps, which can produce a 0% or artificially low reading if the cell shipped below the top threshold. Run one full charge cycle through the Arlo magnetic charging cable until the indicator reaches 100%, then allow the camera to draw the cell down to approximately 20% before recharging. After that single cycle the voltage-to-percentage mapping aligns and readings stabilise.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377783046234,"sku":"BWCS-NAR700XL-1","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377783079002,"sku":"BWCS-NAR700XL-2","price":62.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377783111770,"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\/netgear-arlo-pro-3-replacement-battery-37v-13400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
