It fits the portable suction device used for airway management in emergency and clinical settings. Voltage, capacity, and connector match the OEM specification (part no. 637145600125).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAtmos Emergency Suction compatibility:\u003c\/strong\u003e\n    The Atmos Emergency Suction platform runs a 7.4V dual-cell Li-ion configuration with a BMS that validates cell voltage at startup. This replacement uses the same voltage rail and connector pinout, so the BMS handshake completes without error on power-on.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through the Atmos Emergency Suction's startup sequence and load profile. The BMS accepted the cell, completed its verification routine, and held voltage within the expected band under suction load. No false fault codes were logged.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePower-on self-test protocol:\u003c\/strong\u003e\n    After installing this battery, let the device run its full power-on self-test without interruption. The Atmos Emergency Suction runs BMS verification at startup — cutting power mid-sequence triggers a persistent battery fault flag that clears only on a complete reboot cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Atmos Emergency Suction alarms low battery on a freshly charged replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe device's charge IC applies a conservative voltage threshold tuned to an aged OEM cell. A new cell has a slightly different open-circuit voltage profile in the first few cycles, which the BMS can misread as below threshold. The low-battery alarm fires even though the cell is fully charged. One complete charge-discharge cycle recalibrates the BMS reference and clears the false alarm on subsequent startups.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not powering on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage, and the Atmos Emergency Suction's BMS has a recovery floor — typically around 2.5V per cell. If the replacement battery dropped below that threshold before installation, the BMS blocks power-on as a protection measure. Connect the device to its charger for at least 30 minutes before attempting to power on; this allows the charge IC to push the cell above the BMS recovery threshold. If the charger LED shows activity, the cell is recovering — wait for a stable charge indication before powering the device on.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381472231514,"sku":"BWCS-ATS125MD-1","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381472264282,"sku":"BWCS-ATS125MD-2","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381472297050,"sku":"BWCS-ATS125MD-3","price":60.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ATS125MD-1.webp?v=1778901051","url":"https:\/\/batteryweb.com\/products\/atmos-emergency-suction-replacement-battery-74v-6800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
