The original cell degrades with repeated shallow-cycle use — common in office and mobile environments — until the headset can no longer sustain a full call. This replacement restores the pack to original capacity.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eElite 162 and Explorer series compatibility:\u003c\/strong\u003e\n    These models share the same 3.7V cell, connector pinout, and BMS handshake protocol. Swapping to this pack requires no modification — the base station communicates with the BMS identically to the factory cell.\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 on the Explorer 340 platform. The BMS reported correct state-of-charge to the base station and held voltage above the 3.2V cutoff threshold under combined audio and DECT radio draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge after fitting:\u003c\/strong\u003e\n    Seat the headset in the base station and allow a complete uninterrupted charge cycle before taking a call. DECT headsets log the new cell during this cycle — skipping it causes the base to display an inaccurate talk-time estimate.\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 new pack after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDECT base stations handshake with the headset BMS to track cell state. If the cell arrives at storage voltage — typically around 3.6V — the base may show a charging error or fail to register the pack at all. Place the headset in the cradle immediately after fitting. The BMS initialisation completes during the first full charge cycle, after which the base station reads capacity and charge state correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHeadset cuts out mid-call even with a recently charged battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Elite 162 and Explorer headsets draw current from two simultaneous loads — the audio codec and the DECT radio transmitter. Under that combined draw, a degraded or under-conditioned cell can sag below the BMS cutoff voltage briefly, dropping the headset off the call. This is not a headset fault. Run three to five complete charge and discharge cycles to bring the cell to rated capacity. After conditioning, voltage sag under combined load stays within the BMS window and dropouts stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428156276826,"sku":"BWCS-PEX340SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428156309594,"sku":"BWCS-PEX340SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428156342362,"sku":"BWCS-PEX340SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PEX340SL_1.webp?v=1779934278","url":"https:\/\/batteryweb.com\/products\/plantronics-elite-162-replacement-battery-37v-140mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
