This battery (PN: 01573) is the standard replacement for the Stephan Sophie electric-driven ventilator platform. It is compatible with all Sophie transport and ICU ventilator configurations that use the 7S2P INR-18650PB2 battery system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: Can I use a third-party charger?\u003c\/strong\u003e\u003cbr\u003eA: No. The Sophie ventilator has a built-in charging circuit. Always charge through the ventilator's AC power connection — third-party chargers bypass the BMS and can cause uneven cell charging across the 7-series groups.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: How do I verify this is a genuine 01573 replacement?\u003c\/strong\u003e\u003cbr\u003eA: Check the label for the 01573 part number and 25.2V \/ 3000mAh rating. Inspect the connector — it should match the Sophie ventilator's battery bay without force. All our batteries include a QC test report with individual cell group voltages.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: What is the expected runtime on a full charge?\u003c\/strong\u003e\u003cbr\u003eA: Runtime varies by ventilator settings (tidal volume, respiratory rate, PEEP, FiO2). Expect 4-8 hours for typical transport settings and 2-4 hours for ICU-level support with higher flow rates.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Stephan","offers":[{"title":"Default Title","offer_id":46316012798124,"sku":"01573-25.2V-3000mAh","price":249.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0429\/2047\/6834\/files\/Stephan-01573-25.2V-3000mAh-Medical-Battery-3.jpg?v=1779928569","url":"https:\/\/www.batterymall.com\/en-nl\/products\/01573-replacement-battery-stephan-sophie-ventilator-7s2p","provider":"BatteryMall.com","version":"1.0","type":"link"}
