It fits the NC5100US, C1241290, and Vido Doorbell Wired variants. Same voltage and footprint as the factory cell — no modifications needed.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNC5100US and C1241290 compatibility:\u003c\/strong\u003e\n    Both models share the same 3.7V power rail, connector pitch, and BMS handshake protocol. The 28.20 × 16.65 × 6.60mm form factor fits the battery bay in all three listed variants 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 charge and discharge on the Nest Hello platform. The BMS accepted the cell without error flags, held voltage within spec under camera-active and two-way audio loads, and did not trigger low-voltage cutoff during motion-event bursts.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install power cycle:\u003c\/strong\u003e\n    After fitting this cell, perform one full power cycle through the Nest app before relying on motion recording. The firmware must register the new cell before motion event logs sync correctly to cloud storage — skipping this step causes missed clips.\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 app after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSwapping the battery on the Nest Hello clears the active session token the app holds for that device. The doorbell reboots, but the app does not automatically re-establish the connection — it waits for a handshake that never completes. This leaves the device showing as offline even though the hardware is powered and functional. Fix this by opening the Nest app, navigating to the device settings, and removing then re-adding the doorbell to force a new session token exchange.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eApp reporting 0% or incorrect charge percentage after install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Nest Hello uses a voltage-threshold indicator — not a fuel gauge IC — to estimate charge level. A new cell sitting at storage voltage reads outside the thresholds the firmware expects, so the app displays 0% or an inaccurate figure immediately after install. Run one complete charge cycle through the doorbell's wired connection before trusting the percentage shown. After a full charge and a single discharge under normal use, the voltage thresholds recalibrate and the app displays an accurate level — confirm by checking the app shows above 3.6V at rest.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377784356954,"sku":"BWCS-NLH510SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377784389722,"sku":"BWCS-NLH510SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377784422490,"sku":"BWCS-NLH510SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NLH510SL-1.webp?v=1778772243","url":"https:\/\/batteryweb.com\/products\/nest-hello-replacement-battery-37v-280mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
