It slots into the internal battery bay and provides backup power during transport or mains interruption. Voltage, chemistry, and terminal configuration match OEM part B11152.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e754 Eagle and 326 Aspirator platform:\u003c\/strong\u003e\n    Both units share the same 12V SLA bay, connector orientation, and BMS handshake protocol — a single cell spec covers the full device family listed under this part number.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the 754's self-test sequence and confirmed the BMS accepted charge, passed the internal resistance check, and released to run mode without a fault code.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After swapping the cell, allow the ventilator to complete its full power-on self-test without interruption. Cutting power mid-sequence causes the BMS to log 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\"\u003eWhy the 754 Eagle flags a battery fault on the first charge cycle\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 754's charge IC applies a conservative acceptance threshold tuned to a broken-in OEM cell. A new SLA cell presents slightly higher internal resistance until it completes its first full charge-discharge cycle. The BMS reads this resistance delta as a marginal cell and may not release the fault flag even when the battery reaches full voltage. Running one complete charge-discharge cycle normalises the cell's internal resistance and allows the BMS to pass the threshold on the next startup check.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator stalled below 100% after installing a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSLA cells stored before sale develop a surface charge pattern the charge IC doesn't recognise as a fully conditioned cell. The 754's charging circuit responds by capping current early and displaying an incomplete charge state. This is not a cell defect — it clears after one full discharge to approximately 10.5V followed by a slow recharge. After that cycle, the charge indicator tracks correctly and the device passes its pre-transport battery check.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381460566106,"sku":"BWCS-MDL754MD-1","price":146.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381460598874,"sku":"BWCS-MDL754MD-2","price":170.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381460631642,"sku":"BWCS-MDL754MD-3","price":188.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MDL754MD-1.webp?v=1778900983","url":"https:\/\/batteryweb.com\/products\/impact-medical-754-eagle-uni-vent-ventilator-replacement-battery-12v-5000mah-sealed-lead-acid","provider":"BatteryWeb","version":"1.0","type":"link"}
