It fits into the original housing and reconnects to the headset's charging and audio circuitry. Swap this in when your original cell no longer holds charge through a full call.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHeadset pack compatibility:\u003c\/strong\u003e\n    Wireless headsets using the AHB472625PST share a common small-form Li-Polymer format — same footprint at 27.96 x 28.08 x 6.50mm, same voltage rail, same connector orientation. The BMS on the base station expects a 3.7V nominal cell; this replacement meets that handshake without modification.\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 the bench, confirmed BMS recognition at the base station, and verified the protection circuit trips correctly under over-discharge conditions before shipment.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on a DECT base station:\u003c\/strong\u003e\n    Place the headset in the base and let it complete one full uninterrupted charge cycle before making a call. DECT base stations log the new cell during this cycle — without it, the talk-time indicator reads from stale data and the headset may report incorrect charge levels.\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 full charge but headset cuts off after short use\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-Polymer cell ships at storage voltage — typically 3.6–3.8V, not fully topped. The base station may interpret this as charged and stop the charging cycle early. The headset then runs off a cell that was never fully conditioned. One complete charge cycle from the base corrects this; the base resets its charge log and fills the cell to proper capacity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHeadset cutting out mid-call on a freshly installed battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDECT headsets draw from two systems simultaneously — the audio codec and the radio transmitter. On a new or unconditioned cell, this combined draw can pull voltage below the BMS cutoff threshold briefly, tripping a protection disconnect. This is not a faulty cell. Run three to five full charge and discharge cycles through the base station and the protection circuit becomes less likely to trip under normal combined load. If dropout continues after five cycles, check that the cell connector is fully seated in the housing.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428155457626,"sku":"BWCS-LOH800SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428155490394,"sku":"BWCS-LOH800SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428155523162,"sku":"BWCS-LOH800SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LOH800SL_1.webp?v=1779934278","url":"https:\/\/batteryweb.com\/products\/synergy-replacement-battery-37v-230mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
