It also fits the SRH remote headsets, WT5S, and WiTalk DRH units. Capacity matches OEM spec at 950mAh (3.52Wh) — no modifications needed to fit.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWiTalk platform fit:\u003c\/strong\u003e\n    The Hub, SRH, WT5S, and DRH units share the same 3.7V cell format and connector pinout. The BMS on each unit expects the same voltage curve, so one cell spec covers the entire WiTalk ecosystem without wiring changes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through a full charge-discharge cycle on the Hub base station. The BMS accepted the pack on first insertion, held charge without fault flags, and maintained stable voltage through the combined DECT radio and audio draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle conditioning on the Hub:\u003c\/strong\u003e\n    Seat the new pack and leave it on charge in the base station for a complete cycle before your first session. The Hub logs the new cell during that first charge pass — without it, the talk-time indicator will read inaccurately for several cycles.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station not recognising the new pack after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe WiTalk Hub BMS performs a handshake with the cell on insertion. If the pack arrives at storage voltage — typically around 3.6V — the BMS may flag a charge error or show no recognition at all. This is not a faulty cell. Place the Hub on its charger for at least 30 minutes before expecting the status LED to clear. If the error persists past that point, reseat the connector and confirm the ribbon contacts are fully engaged before assuming the cell is at fault.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHeadset cutting out mid-call despite a full charge reading\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe WiTalk system draws current simultaneously for DECT radio transmission and audio processing. Under that combined load, a cell that has not completed conditioning cycles can sag below the BMS cutoff threshold even when the indicator shows full. The Hub's charge display measures resting voltage — not load voltage — so a shallow cell looks fine until transmission starts. Run three to five full charge-discharge cycles and the cutout behaviour typically resolves as the cell reaches its rated 950mAh delivery under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428096311386,"sku":"BWCS-SWK100SL-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428096344154,"sku":"BWCS-SWK100SL-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428096376922,"sku":"BWCS-SWK100SL-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SWK100SL-1.webp?v=1779934086","url":"https:\/\/batteryweb.com\/products\/saramonic-hub-intercom-base-station-replacement-battery-37v-950mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
