It matches the OEM part numbers 70868-01, 73366-01, AHB371030PA, and PA-PL002. Swap it when the original cell no longer holds a charge through a full call.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBT250V \/ BT500V \/ BT2010 \/ BT2020 fit:\u003c\/strong\u003e\n    These models share the same 3.7V cell format, connector pinout, and BMS handshake protocol. One cell covers the whole group — voltage rail and physical dimensions are identical across the lineup.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on a BT250V unit. The BMS accepted the pack without error, balanced correctly at full charge, and cut off cleanly at the low-voltage threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for DECT and Bluetooth headsets:\u003c\/strong\u003e\n    Place the headset in its base station and run a complete charge cycle before taking any call. The base needs to log the new cell before its talk-time estimate can track accurately — skipping this step causes the indicator to read incorrectly for several cycles.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the BT250V cuts out mid-call on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe BT250V draws simultaneously from the audio codec and the Bluetooth radio during active calls. In a housing this compact, that combined load creates momentary voltage sag — especially if the new cell hasn't completed its first full charge cycle. The BMS interprets the sag as a low-voltage event and interrupts power. A complete first charge cycle before use brings the cell to its rated capacity and reduces sag under combined draw.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows full charge but headset drops off after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when a replacement cell arrives at storage voltage — typically around 3.6V — rather than fully charged. The base station's charge indicator may show complete before the cell has actually reached 4.2V. The headset then pulls load from a partly charged pack and the BMS cuts out quickly. Put the headset back in the base for a second uninterrupted charge cycle and confirm the cell reaches 4.2V before use.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428156178522,"sku":"BWCS-PEX340SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428156211290,"sku":"BWCS-PEX340SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428156244058,"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\/jabra-bt250v-replacement-battery-37v-140mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
