When AC power drops, the modem draws from this battery to keep your internet and VoIP line active. It replaces the original internal cell that degrades after repeated charge cycles.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eU10C022, U10C017, and DVW3201 compatibility:\u003c\/strong\u003e\n    These three UBEE units share the same 10.8V backup battery bay, connector pinout, and BMS handshake protocol — the modem firmware recognises cell state through the same charge controller across all three models.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through the UBEE charge controller and confirmed the BMS accepted the cell without fault codes. The protection circuit held cutoff at the correct low-voltage threshold and resumed charge normally.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge protocol:\u003c\/strong\u003e\n    After fitting the battery, leave the modem on AC power for at least 4 hours before any outage test. UBEE firmware will not route backup power through a cell it hasn't completed a charge cycle on — running a test before that window causes a false failure reading.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery self-test failing after a fresh swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eUBEE modems run an automatic self-test shortly after detecting a new battery. If the cell hasn't reached a full charge state, the firmware logs a test failure and may flag a battery fault LED. This isn't a defective cell — it's the firmware rejecting an incomplete charge. Allow 4 hours on AC power, then let the modem run its next scheduled self-test cycle. The fault clears once the battery holds above 12.4V at rest.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eInternet stays up during an outage but VoIP calls drop immediately\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eData traffic runs on lower sustained current than VoIP. During a power outage, the modem prioritises packet routing, but an ageing or partially charged battery can't sustain the power draw that voice calls require. The battery voltage sags under VoIP load and the modem's voice module drops first. Confirm the battery has completed a full charge cycle and check that resting voltage sits at 12.4V or above before assuming the cell is faulty.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333524258906,"sku":"BWCS-CPB013RX-1","price":59.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333524291674,"sku":"BWCS-CPB013RX-2","price":70.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333524324442,"sku":"BWCS-CPB013RX-3","price":77.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CPB013RX-1.webp?v=1778212933","url":"https:\/\/batteryweb.com\/products\/ubee-u10c022-replacement-battery-108v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
