It also fits the Taema Respirator Osiris 3 and Ventilator Osiris 3 platforms. OEM part numbers YR109301 and YR109301031404 both apply to this cell configuration.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOsiris 3 platform fit:\u003c\/strong\u003e\n    The Blease 5500, Taema Respirator, and Ventilator Osiris 3 share the same battery bay geometry, voltage rail, and connector. All three draw from this 9.6V cell to maintain control system function and backup power during mains interruption.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through charge and load sequences matching the Osiris 3's backup draw profile. The BMS accepted the cell without fault codes on a conditioned unit after one full charge-discharge cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, allow the Osiris 3 to complete its full power-on self-test without interruption. The device runs a BMS verification sequence at startup — cutting power during this step generates 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\"\u003eSelf-test failure after battery swap on the Osiris 3\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Osiris 3 runs an internal BMS learn cycle during its first few charge-discharge sequences with a new cell. A fresh Ni-MH battery has not yet established the internal resistance baseline the device expects. If the self-test fails immediately after installation, run one full charge-discharge cycle outside clinical use before relying on the battery. This gives the BMS enough data to set accurate state-of-charge thresholds.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on the first charge after installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge, the Osiris 3's charge IC applies a conservative current limit against a new Ni-MH cell — this is normal behaviour, not a cell fault. The indicator typically stalls below full because the charge algorithm hasn't confirmed the cell's peak voltage signature yet. Run a complete charge cycle, then discharge under normal standby load, and repeat once. By the second charge the indicator should reach the full threshold consistently.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381356363866,"sku":"BWCS-ART300MD-1","price":76.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43381356396634,"sku":"BWCS-ART300MD-2","price":90.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43381356429402,"sku":"BWCS-ART300MD-3","price":101.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ART300MD-1.webp?v=1778900199","url":"https:\/\/batteryweb.com\/products\/air-liquide-blease-5500-osiris-3-replacement-battery-96v-1500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
