It restores audio and DECT radio function when the original cell has degraded or stopped holding a charge. Capacity is 380mAh (1.41Wh) — matched to the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEvolve2 65 and Evolve 2 fit:\u003c\/strong\u003e\n    Both models use the same cell format, connector, and BMS handshake protocol. The 34.80 × 15.20 × 6.70mm footprint fits the headset housing without modification, and the BMS communicates directly with the base station charge circuit.\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 Evolve2 65. The BMS negotiated correctly with the base station, accepted a full charge without fault flags, and delivered stable voltage under combined audio and DECT radio draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle base station protocol:\u003c\/strong\u003e\n    Place the headset in the base station and allow a complete charge cycle before making any calls. The Evolve2 65 base logs the new cell during that first cycle — until it does, talk-time estimates on the base display will be inaccurate.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Evolve2 65 cuts out mid-call even with a new battery installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Evolve2 65 draws from the cell for both audio processing and the DECT radio simultaneously. Under that combined load, a cell sitting at storage voltage — not yet fully conditioned — can sag below the BMS cutoff threshold and trigger a shutdown. This is not a faulty cell. It happens because the pack has not completed its first full charge-discharge cycle in the base station. Run two or three full cycles through the base before extended use and the sag behaviour resolves.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows full charge but headset cuts off after a short time\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen a replacement cell arrives at storage voltage (typically around 3.6–3.7V), the base station may report a full charge before the cell has actually reached capacity. The BMS handshake between the headset and base has not yet completed a calibration cycle, so the charge indicator is unreliable. Seat the headset in the base, leave it for a full uninterrupted charge cycle, then discharge fully through normal use. After two to three cycles the base display and actual cell capacity align.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428097622106,"sku":"BWCS-JPR265SL-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428097654874,"sku":"BWCS-JPR265SL-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428097687642,"sku":"BWCS-JPR265SL-3","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-JPR265SL-1.webp?v=1779934061","url":"https:\/\/batteryweb.com\/products\/jabra-evolve2-65-replacement-battery-37v-380mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
