It fits the U10C022, U10C017, and DVW3201 — modems commonly deployed by ISPs for residential broadband and VoIP service. When mains power drops, this battery keeps the modem running so internet and phone calls stay active.\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    All three models share the same 10.8V three-cell battery bay, connector pinout, and BMS handshake protocol — so one battery covers the full range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this battery through the modem's charge controller and confirmed the BMS completed its initialisation handshake. The modem accepted the cell, cleared the battery-fault LED, and began the charge cycle normally.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge cycle:\u003c\/strong\u003e\n    After swapping the battery, leave the modem plugged into mains power for at least 4 hours before testing backup function. The modem's firmware will not commit the battery to active standby until it has completed one full supervised charge cycle — testing before that point will show a failure even if the battery is good.\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 immediately after swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eUBEE modems run an automatic battery self-test shortly after detecting a new cell. If the battery hasn't reached a full charge state, the firmware will log a test failure even if the cell is healthy. The self-test threshold on these models requires the pack to hold above 12.0V under light load — a freshly installed battery often sits below that until fully charged. Allow a full 4-hour charge on mains before the modem triggers its next scheduled test.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eVoIP calls drop during outage but internet stays up\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DOCSIS data stack and the embedded MTA (Media Terminal Adapter) that handles VoIP draw different sustained loads. During a power outage, the MTA requires a higher and more stable current than the data path alone. If the backup battery is partially discharged or has degraded cells, voltage can sag enough to drop the MTA while the data connection holds. Check the battery's charge status in the modem's web interface — navigate to the battery or backup status page and confirm voltage is reading at or above 12.0V before relying on it for calls.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333530484826,"sku":"BWCS-CPB013RC-1","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333530517594,"sku":"BWCS-CPB013RC-2","price":62.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333530550362,"sku":"BWCS-CPB013RC-3","price":69.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CPB013RC-1.webp?v=1778212933","url":"https:\/\/batteryweb.com\/products\/ubee-u10c022-replacement-battery-108v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
