It fits the A190 directly, restoring full audio and radio operation to the headset. Dimensions are 37.00 × 25.00 × 4.50mm — confirm these against your existing cell before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eA190 fit confirmed:\u003c\/strong\u003e\n    The A190 runs a single-cell Li-Polymer pack at 3.7V nominal. The AK320A connector and BMS handshake protocol are matched to the base station's charge controller, so the dock reads state-of-charge correctly from the first cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through combined DECT radio and audio draw, monitoring BMS cutoff thresholds. The protection circuit tripped correctly at low-voltage and recovered cleanly on reinsertion into the base station.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle base station protocol:\u003c\/strong\u003e\n    Before taking a call, seat the headset in the base and let it complete one full charge cycle. The A190's base station logs the new cell during this cycle — skipping it causes the talk-time indicator to read inaccurately for several sessions.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station not recognising the new pack after fitting\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe A190 base station completes a BMS handshake when a new cell is seated. If the pack arrived at storage voltage — typically around 3.6–3.65V — the base may display a charge error or show no activity. This happens because the BMS protection circuit has not yet been initialised by a charge event. Seat the headset firmly, leave it undisturbed in the cradle for at least 30 minutes, and the base should begin the charge cycle and clear the error.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHeadset cuts out mid-call even with a new battery fitted\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe A190 pulls current simultaneously from the audio circuit and the DECT radio during active calls. Under combined load, a cell sitting near the low-voltage cutoff — around 3.0V — will trigger the BMS protection and drop the headset offline instantly. This is not a fault with the replacement cell; it means the previous charge cycle was incomplete. Return the headset to the base for a full uninterrupted charge, then confirm the base indicator shows 100% before the next call.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428105945178,"sku":"BWCS-SNA190SL-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428105977946,"sku":"BWCS-SNA190SL-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428106010714,"sku":"BWCS-SNA190SL-3","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SNA190SL-1.webp?v=1779934133","url":"https:\/\/batteryweb.com\/products\/snom-a190-replacement-battery-37v-320mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
