It restores power to the audio and DECT radio circuits that handle transmission and reception. Capacity matches the original pack at 6.66Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBeltStations and MasterBelt compatibility:\u003c\/strong\u003e\n    Both models run on the same 3.7V cell with the same physical footprint — 52.25 × 43.00 × 15.60mm. The connector pinout and BMS voltage thresholds are shared across this platform, so one cell covers both.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through combined audio and DECT radio draw — the two loads run simultaneously during active calls. The BMS held charge termination and cutoff within spec across multiple discharge cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol on DECT headsets:\u003c\/strong\u003e\n    Seat the headset in the base station and let it complete one full charge cycle before making a call. The base station needs that cycle to log the new cell — until it does, the talk-time estimate on the base display will read inaccurately low.\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 fitting\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDECT base stations log the battery's BMS state during the first full charge handshake. If the cell arrives at storage voltage — typically around 3.6–3.7V — the base may flag a charging error or show no charge activity at all. This is not a faulty cell. Place the headset in the cradle, leave it undisturbed for a full charge cycle, and the base will complete the handshake. Once logged, normal charge indication resumes.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHeadset cutting out mid-call on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe BeltStations platform draws current from two sources simultaneously — the audio codec and the DECT radio transmitter. Under that combined load, a cell that has not completed conditioning cycles yet can sag below the BMS cutoff threshold briefly, dropping the headset. This typically clears after three to five full charge-discharge cycles as the cell reaches stable capacity. If cutouts persist past cycle five, check the headset's contact pins against the battery terminals — oxidised contacts increase resistance and amplify voltage sag at the cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428121116762,"sku":"BWCS-HMT200TS-1","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428121149530,"sku":"BWCS-HMT200TS-2","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428121182298,"sku":"BWCS-HMT200TS-3","price":45.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HMT200TS-1.webp?v=1779934163","url":"https:\/\/batteryweb.com\/products\/pliant-beltstations-replacement-battery-37v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
