It fits both the Acutronic Bird Fabian and Bird Fabian platform variants that use OEM part number 110707. The battery provides backup power during patient transport or brief mains interruption in the ICU.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFabian platform battery fit:\u003c\/strong\u003e\n    The Bird Fabian and Acutronic Bird Fabian share the same 13.2V Ni-MH battery bay, connector pinout, and BMS handshake protocol. Both variants accept this cell without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the Fabian's charge management circuit and confirmed the BMS accepted the cell, completed charge termination at full capacity, and did not flag a chemistry mismatch fault on the device status screen.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test on the Fabian:\u003c\/strong\u003e\n    After fitting this battery, allow the Fabian to complete its full power-on self-test without interruption. The ventilator's BMS runs a verification sequence at startup — cutting power mid-cycle writes a battery fault flag 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 Fabian flags a battery fault after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Fabian's charge IC applies a conservative capacity threshold during the first charge cycle on a new Ni-MH cell. If the cell voltage curve doesn't match the stored OEM profile exactly, the BMS logs a conditional fault rather than passing the battery outright. This is not a defect — it clears after one complete charge-discharge cycle has recalibrated the BMS learn register. Run a full cycle before placing the unit back into clinical rotation.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFabian won't power on after battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge at roughly 20–30% per month under typical storage conditions. If a replacement cell has been stored several months before installation, its resting voltage may fall below the Fabian's BMS recovery threshold — typically around 10.5V for a 13.2V Ni-MH pack. The device will not boot because the BMS blocks startup to prevent undervoltage damage to connected circuitry. Connect the Fabian to mains power and allow a full uninterrupted charge before attempting to power on from battery alone.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381461057626,"sku":"BWCS-AVS110MD-1","price":106.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381461090394,"sku":"BWCS-AVS110MD-2","price":122.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381461123162,"sku":"BWCS-AVS110MD-3","price":134.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AVS110MD-1.webp?v=1778900983","url":"https:\/\/batteryweb.com\/products\/viasys-healthcare-acutronic-bird-fabian-replacement-battery-132v-4500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
