It also fits the PB560 and the Airox Legendair ventilator. This battery powers the device during patient transport and operation away from mains supply.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePB560 and Legendair platform fit:\u003c\/strong\u003e\n    These ventilators share the same 25.2V battery bus, connector footprint, and BMS handshake protocol. One battery cell configuration covers both platforms without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran charge-discharge cycles on this battery and confirmed the BMS communicates correctly with the PB560's battery management interface. State-of-charge reporting and low-battery threshold triggering both behaved within normal parameters.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePower-on self-test protocol:\u003c\/strong\u003e\n    After installing this battery, let the ventilator complete its full power-on self-test without interruption. The device runs BMS verification at startup — cutting power during this sequence can trigger a false battery fault that persists until the next complete reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSelf-test failure after battery swap on the PB560\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe PB560 runs a BMS learn cycle during its first post-installation self-test. A new cell that hasn't completed one full charge-discharge cycle may not meet the charge IC's verification threshold, causing the self-test to flag a battery fault. This is not a defective battery. Complete one full charge cycle to 25.2V, then run a full discharge under normal ventilator load before returning the unit to clinical use. After that cycle, the self-test passes consistently.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator stalls below 100% on first charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge after installation, the PB560's charge IC applies a conservative upper voltage limit to an uncharacterised cell. This causes the charge indicator to plateau short of 100%, even after several hours on charge. The battery is not at fault and is not defective. Allow the unit to complete the full first charge cycle without removing it — after one complete cycle the charge IC recalibrates and the indicator reaches full charge correctly on subsequent cycles.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381383987290,"sku":"BWCS-CDN560MD-1","price":408.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381384020058,"sku":"BWCS-CDN560MD-2","price":488.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381384052826,"sku":"BWCS-CDN560MD-3","price":547.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CDN560MD-1.webp?v=1778900493","url":"https:\/\/batteryweb.com\/products\/medtronic-puritan-bennett-560-ventilator-replacement-battery-252v-4800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
