It fits the OEM part numbers VM9158 and 07-SOLOMICBATTERY. When the original cell degrades and talk time drops noticeably, this is the direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSolo Field and Solo Executive compatibility:\u003c\/strong\u003e\n    Both headsets share the same battery bay dimensions and the same BMS handshake protocol with their respective base stations. The connector orientation and cell profile — 52.00 × 13.96 × 5.76mm — are identical across all listed fit models, including 02-DSKSYS-D and 06-XLRMIC-BLK-11.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the cell through charge and discharge cycles on a Solo Field unit. The BMS completed the handshake with the base station within the first full charge cycle, and the base showed a correct charge status without error flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle base station logging:\u003c\/strong\u003e\n    Seat the headset in its base station and run a complete charge before taking a call. DECT headsets must complete one full base-logged cycle before the talk-time counter reads accurately — skipping this step causes the base to underreport remaining charge.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing charging error after fitting the new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-Polymer cell ships at storage voltage — typically around 3.6V — which sits just below the threshold the Solo base station expects for a recognised, healthy pack. The base can flag this as a fault rather than initiating a charge cycle. Place the headset in the cradle and leave it undisturbed for at least 15 minutes; most bases will then re-attempt the BMS handshake and begin charging normally. If the error persists, remove the headset, wait 30 seconds, and reseat it to trigger a fresh handshake cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHeadset cutting out mid-call on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Solo headset draws simultaneously from the audio circuit and the DECT radio transmitter. Under that combined load, a cell that has not yet completed its first full conditioning cycle can sag in voltage enough to trip the BMS cutoff — even if the base showed a full charge beforehand. This is not a faulty cell; it resolves over three to five full charge-discharge cycles as the Li-Polymer electrolyte settles. After conditioning, voltage sag under dual load drops and mid-call cutouts stop. Confirm the cell is above 3.7V resting voltage before the next call to rule out a genuinely depleted pack.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428124754010,"sku":"BWCS-RVS915SL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428124786778,"sku":"BWCS-RVS915SL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428124819546,"sku":"BWCS-RVS915SL-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RVS915SL-1.webp?v=1779934244","url":"https:\/\/batteryweb.com\/products\/revolabs-solo-field-replacement-battery-37v-200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
