It restores the phone's ability to hold power when mains supply drops, keeping VoIP calls and saved settings intact. Voltage and capacity match the original cell exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSMC Skype Wifi Phone fit:\u003c\/strong\u003e\n    This phone runs a single-cell Li-ion pack at 3.7V nominal. The backup circuit draws directly from this cell during outages — voltage, connector, and physical dimensions all need to match the original for the phone to recognise and use the battery correctly.\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 and confirmed the BMS accepts a charge from the phone's internal charging circuit without fault flags. Capacity held within expected range of the 1050mAh rating across multiple cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge requirement:\u003c\/strong\u003e\n    After fitting this battery, leave the phone on mains power for a full 4 hours before testing backup function. The phone's firmware will not route power through the backup circuit until the cell clears a minimum charge threshold — testing too early will make it appear the battery isn't working.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the SMC Skype Wifi Phone loses saved settings during a power cut\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the backup battery is depleted or missing, the phone has no power source to hold volatile memory during mains loss. Network credentials, Skype account data, and call settings are stored in RAM that needs continuous power to persist. A degraded cell can measure 3.7V at rest but collapse under the small load the phone's memory circuit draws. Replacing the cell and completing a full charge cycle before the next outage is the only fix.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery warning showing immediately after installing a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new battery shipped from storage can sit at 3.2–3.3V, which is below the threshold the phone's firmware uses to clear a low-battery flag. The phone reads state-of-charge from voltage, not from a fuel gauge chip, so a partially discharged new cell triggers the same warning as a worn-out one. Connect the phone to mains and allow the cell to charge uninterrupted — the warning clears once the cell climbs past approximately 3.6V. Do not assume the replacement cell is faulty until it has completed at least one full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428090904666,"sku":"BWCS-BKW001SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428090937434,"sku":"BWCS-BKW001SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428090970202,"sku":"BWCS-BKW001SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BKW001SL-1.webp?v=1779934014","url":"https:\/\/batteryweb.com\/products\/smc-skype-wifi-phone-replacement-battery-37v-1050mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
