It fits devices using OEM part numbers 68339, 68339A, 68339K, AMED0013, B11407, BMED11407, and OM11407. These units are used in non-invasive ventilation support and sleep apnea therapy delivery in clinical settings.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e6068 and Avea SEBAC platform fit:\u003c\/strong\u003e\n    Both the 6068 and Avea SEBAC share the same 24V battery bay, connector pinout, and BMS handshake protocol. One battery part number covers the full range because the charge management IC and thermal cutoff logic are identical across these models.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through the full charge-discharge profile the 6068 BMS expects. The thermal cutoff engaged correctly at elevated draw, and the BMS passed the cell voltage verification sequence without flagging a fault on the first boot.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After installing this battery, allow the device to complete its full power-on self-test without interruption. The 6068 BMS runs a voltage and impedance check at startup — cutting power mid-sequence stores a false battery fault that persists until the next clean reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm triggering on the 6068 immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe 6068 BMS was calibrated to the impedance profile of an aged OEM Ni-MH cell. A new cell has lower internal resistance, which the BMS can misread as a voltage anomaly during the initial self-test. The alarm clears after one full charge-discharge cycle gives the BMS enough data to re-anchor its cell model. Charge to full, run the device through a complete session under normal load, then recharge — the alarm should not return after that cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not completing boot sequence after battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge at roughly 1–2% per day in storage. If the cell voltage dropped below the 6068's BMS recovery threshold — typically around 20V for a 24V pack — the firmware will refuse to boot rather than risk a brownout during the ventilation cycle. Connect to mains power first and let the charger run a trickle recovery cycle for at least two hours before attempting to boot on battery alone. Check the battery indicator on the device panel — if it climbs past 22V, the BMS will release the boot lock.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381451456602,"sku":"BWCS-AVS683MD-1","price":179.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381451489370,"sku":"BWCS-AVS683MD-2","price":210.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381451522138,"sku":"BWCS-AVS683MD-3","price":233.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AVS683MD-1.webp?v=1778900876","url":"https:\/\/batteryweb.com\/products\/viasys-healthcare-6068-replacement-battery-24v-4000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
