It fits Voyager Legend variants 87300-01, 87300-02, 87300-03, and additional models in the Voyager Legend series. Same voltage, same chemistry, same compact form factor at 35.80 x 7.50 x 4.10mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVoyager Legend series fit:\u003c\/strong\u003e\n    All Voyager Legend variants listed share the same internal cell bay dimensions, connector pin-out, and BMS communication protocol. Swapping the cell does not require firmware changes — the headset reads the new pack automatically on first charge.\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 Voyager Legend platform. The BMS completed its handshake correctly, charge termination triggered at full voltage, and the protection circuit held steady under the combined audio and Bluetooth radio draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge via base station:\u003c\/strong\u003e\n    Place the headset in the Plantronics charging cradle immediately after fitting the new cell. The base station logs the new pack and calibrates the talk-time indicator — skipping this step causes the battery gauge to read inaccurately for the first several days.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Voyager Legend cuts out mid-call on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Voyager Legend drives two loads simultaneously — the audio codec and the Bluetooth radio. On a fresh replacement cell at storage voltage, the BMS can interpret the combined current spike as an overload and trip the protection circuit. This shows as a sudden dropout rather than a gradual fade. A full base-station charge cycle before use brings the cell to nominal voltage, which gives the BMS enough headroom to handle the combined draw without cutting out.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than rated for the first few uses\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells arrive at partial charge and do not reach full capacity on cycle one. The Voyager Legend's battery gauge also relies on a calibrated baseline, which the base station writes after the first complete charge-to-discharge sequence. Expect capacity to step up progressively over three to five full cycles. After cycle five, charge fully in the cradle before measuring actual talk time against the rated figure.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428150837338,"sku":"BWCS-JPR031SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428150870106,"sku":"BWCS-JPR031SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428150902874,"sku":"BWCS-JPR031SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-JPR031SL-1.webp?v=1779934222","url":"https:\/\/batteryweb.com\/products\/plantronics-voyager-legend-replacement-battery-37v-60mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
