It cross-references OEM part numbers 110579, 11389, 6038, 8-100152-00, B11511, and OM11511. Verify your OEM part number against this list before fitting.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRespironics 60 Monitor and Criterion 40 compatibility:\u003c\/strong\u003e\n    These models share the same 6V power rail, connector format, and BMS handshake protocol. A single cell pack services all variants in the Criterion 40 family, including the Airway Pressure Monitor configuration, without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full charge and discharge on a Ni-MH compatible charge controller, confirmed the BMS accepted the cell chemistry without fault flags, and verified terminal voltage held above 5.4V under a sustained load profile consistent with oximetry sensor operation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test procedure:\u003c\/strong\u003e\n    After fitting this battery, allow the Respironics 60 Monitor to complete its full power-on self-test without interruption. Medical device BMS firmware runs a verification sequence at startup — cutting power mid-cycle registers 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 Respironics 60 Monitor alarms low battery after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe device BMS stores a charge acceptance profile calibrated to the original OEM cell. A new replacement cell has a slightly different internal resistance signature on the first cycle, which the BMS interprets as insufficient charge rather than a new cell. This is not a fault with the battery. Run one complete charge-discharge cycle and the BMS recalibrates its threshold to match the new cell's actual capacity curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRespironics 60 Monitor not powering on after battery sat unused in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge at roughly 1–2% per day in storage. A cell that has sat uninstalled for several months can drop below the BMS recovery threshold — typically around 4.8V on a 6V pack — and the device will not boot. Place the pack on a compatible Ni-MH charger for a full charge cycle before attempting to power on the monitor. If the charger does not detect the cell, check terminal voltage with a multimeter; below 4.5V, the pack may require a trickle pre-charge before the main charge cycle can begin.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381368356954,"sku":"BWCS-RPC400MD-1","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381368389722,"sku":"BWCS-RPC400MD-2","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381368422490,"sku":"BWCS-RPC400MD-3","price":60.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RPC400MD-1.webp?v=1778900303","url":"https:\/\/batteryweb.com\/products\/respironics-60-monitor-replacement-battery-6v-1800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
