It fits the MicroCom XR, MicroCom XR 900MHz, and units listed under part numbers 00004394 and 00004445. Capacity is sourced from product data — 7.03Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMicroCom XR platform fit:\u003c\/strong\u003e\n    These models share the same 3.7V single-cell architecture, BT-01 connector footprint, and BMS handshake protocol — which is why one cell covers both the standard and 900MHz variants without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the MicroCom XR base station and monitored BMS communication. The cell completed the handshake, accepted charge current, and the base cleared its charging error flag within the first full cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for DECT headsets:\u003c\/strong\u003e\n    Dock the headset in the base station and let it complete one full, uninterrupted charge before taking any calls. DECT headsets use the base to calibrate the talk-time counter — skipping this step leaves that estimate inaccurate for the first few 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 showing a charging error after fitting a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe MicroCom XR base station reads the battery's BMS before it starts charging. If the new cell ships at storage voltage — typically around 3.6V — the base may flag a fault instead of entering charge mode. This is not a defective cell. Place the headset in the cradle, leave it undisturbed, and the BMS handshake will complete within a few minutes, after which the charge indicator clears and current begins flowing normally.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHeadset cutting out mid-call even with a recently charged battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe MicroCom XR draws current simultaneously from the audio amplifier and the DECT radio transmitter. Under that combined load, a cell that hasn't completed its first few conditioning cycles can sag below the BMS cutoff threshold briefly, dropping the headset mid-transmission. This is distinct from a short talk time — the cell may show full charge but still sag on peak draw. Run three to five full charge-discharge cycles through the base station; peak voltage stability improves to around 3.7V under load by cycle four.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428106436698,"sku":"BWCS-PMC100SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428106469466,"sku":"BWCS-PMC100SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428106502234,"sku":"BWCS-PMC100SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PMC100SL-1.webp?v=1779934117","url":"https:\/\/batteryweb.com\/products\/pliant-microcom-xr-replacement-battery-37v-1900mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
