It matches the physical footprint at 35.50 × 20.00 × 4.40mm and carries the same OEM part numbers 65358-01, 64399-01, and 64327-01. Swap it when the original cell no longer holds charge through a standard office shift.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHSG-Link DECT 2, AWH55, AWH65 compatibility:\u003c\/strong\u003e\n    These headsets share the same battery bay geometry, connector pinout, and BMS handshake protocol. The 3.7V nominal voltage rail matches the audio codec and DECT radio module requirements across the entire AWH family.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge cycles on a HSG-Link DECT 2 base station and confirmed the BMS completed its handshake, the charge LED cycled correctly, and the protection circuit tripped cleanly at the low-voltage cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge in the base station:\u003c\/strong\u003e\n    Place the headset in its base station and run a complete charge cycle before taking your first call. DECT headsets register the new cell's capacity during this cycle — without it, the base unit's talk-time estimate will read inaccurately for several sessions.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than rated on the first few cycles\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA fresh lithium-polymer cell does not deliver full capacity on cycle one. The electrolyte needs three to five full charge-discharge cycles before the cell reaches rated capacity. On the AWH55 and HSG-Link DECT 2, the combined DECT radio and audio draw accelerates this conditioning because the cell is stressed on every call. By cycle four or five, measured talk time should align with the rated figure.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows full charge but headset cuts off after short use\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA replacement cell shipped at storage voltage — typically around 3.6V — can confuse the base station's charge controller into flagging a premature full-charge state. The headset then enters active use without a properly topped cell and drops out under the combined DECT transmission and audio load. Place the headset in the base for a full uninterrupted charge cycle and confirm the cell reaches 4.2V before use. If the base still flags charge complete within a few minutes, reseat the battery connector and repeat the cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428160241754,"sku":"BWCS-CPB9055-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428160274522,"sku":"BWCS-CPB9055-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428160307290,"sku":"BWCS-CPB9055-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CPB9055-1.webp?v=1779934277","url":"https:\/\/batteryweb.com\/products\/avaya-tenovis-hsg-link-dect-2-replacement-battery-37v-240mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
