It fits VMC4030 and VMS3230 units as well as the broader Pro series. Swap it in when your original cell no longer holds charge or to rotate a spare into service.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePro and Pro 2 compatibility:\u003c\/strong\u003e\n    Both camera generations share the same battery bay dimensions, connector pinout, and 7.4V voltage rail. The BMS handshake is identical across VMC4030 and VMS3230 variants, so one cell covers the full lineup without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a Pro 2 unit. The BMS accepted the cell without fault flags, balanced both internal cells within two cycles, and protection circuits tripped correctly at the expected low-voltage cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eApp registration after swap:\u003c\/strong\u003e\n    On first install, power cycle the camera once through the Arlo app. The firmware must register the new cell before motion recording triggers log correctly to cloud storage — skipping this step can cause missed clip events even when the camera appears online.\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 installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen a new battery is seated, the camera's firmware session token can drop during the power interruption. The base station loses its registered link and the app shows the camera as offline even though the LED is solid. This is a firmware re-registration event, not a battery fault. Open the Arlo app, navigate to Device Settings, and use the Restart option to force the camera back onto the base station sync.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eApp reporting 0% or incorrect battery percentage after install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Arlo Pro uses a voltage-threshold indicator — not a fuel gauge IC — to estimate charge level. If the cell ships at a partial state of charge, the firmware reads the resting voltage and may display 0% or an inaccurate figure until it sees a full charge cycle. Charge the camera to 100% via the Arlo charging cable, then let it discharge through normal use. After one complete cycle the percentage display will align with the actual cell voltage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377786323034,"sku":"BWCS-NAR200SL-1","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377786355802,"sku":"BWCS-NAR200SL-2","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377786388570,"sku":"BWCS-NAR200SL-3","price":45.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NAR200SL-1.webp?v=1778772243","url":"https:\/\/batteryweb.com\/products\/arlo-pro-replacement-battery-74v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
