It restores wireless calling and audio functionality when the original cell no longer holds a usable charge. Voltage and capacity match the OEM specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWave and 100-93040000-02 compatibility:\u003c\/strong\u003e\n    Both the Wave and its regional variant share the same 3.7V power rail, connector pinout, and BMS handshake protocol — one cell covers both. Swapping to a mismatched cell triggers a charging fault at the base station before the headset even powers on.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on the Wave platform. The BMS completed its handshake with the base station correctly, and charge termination triggered at the expected voltage without error flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for the Wave base station:\u003c\/strong\u003e\n    Seat the headset in the base station and leave it for a complete charge cycle before making any calls. The Wave base station logs the new cell during this first cycle — skipping it causes the talk-time indicator to report inaccurately for the first several uses.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Jabra Wave cuts out mid-call on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Wave draws from two loads simultaneously during a call — the audio codec and the Bluetooth radio. On a cell that has not completed its first full cycle, internal resistance is still elevated, and the combined draw causes a brief voltage sag. The BMS interprets this sag as a low-cell condition and trips the output. Running two to three complete charge cycles brings internal resistance down and stops the cutout. If it persists past cycle three, check that the base station contacts are clean and making firm contact with the headset charging pins.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing a full charge but headset dies after a few minutes\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the replacement cell arrives at storage voltage — typically around 3.6V — and the base station's charge circuit reads that as near-full rather than starting a proper charge cycle. The headset appears charged but the cell has not actually received a full top-up. Place the headset in the base, let it sit undisturbed for at least 90 minutes, then remove and re-seat it to force the charge circuit to re-evaluate the cell state. After one complete cycle from this point, the base station talk-time estimate will recalibrate to the actual cell capacity.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428140154970,"sku":"BWCS-JPR100SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428140187738,"sku":"BWCS-JPR100SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428140220506,"sku":"BWCS-JPR100SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-JPR100SL-1.webp?v=1779934222","url":"https:\/\/batteryweb.com\/products\/jabra-wave-replacement-battery-37v-100mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
