It replaces OEM part numbers OM11470, 110376, and 120376. Capacity figure is taken from product data at 72Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePRT4467 and Crossvent 3+\/4+ compatibility:\u003c\/strong\u003e\n    These devices share the same 7.2V battery rail, connector pinout, and BMS handshake protocol. One cell fits all three platforms 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 charge and load on a PRT4467 bench unit. The BMS accepted the cell on first insertion, ran its internal verification, and reported state-of-charge correctly after one full charge-discharge cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePower-on self-test protocol:\u003c\/strong\u003e\n    After installing this battery, let the device complete its full startup self-test without interruption. Medical device BMS firmware runs a verification sweep at boot — cutting power mid-sequence triggers a latching battery fault that won't clear 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\"\u003eDevice not completing boot sequence after battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe PRT4467 and Crossvent units run a BMS learn cycle on first use with a new cell. If the battery has been in storage, its resting voltage may have dropped below the threshold the charge IC needs to begin a normal charge cycle — typically under 6.0V for this 7.2V Ni-MH pack. The device may stall at the boot screen or loop through partial self-tests as a result. Connect to mains power and allow a full uninterrupted charge before attempting to power on from battery alone.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on the first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn first charge, the device's charge IC applies a conservative current limit to a new Ni-MH cell — this is normal behaviour, not a fault. The charge controller is reading cell impedance higher than a conditioned pack, so it throttles back and the percentage climbs slowly or plateaus below 100%. Run one complete charge-discharge cycle and the IC recalibrates its endpoint detection. After that cycle, the indicator should reach full charge and hold correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381382152282,"sku":"BWCS-BMC300MX-1","price":228.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381382185050,"sku":"BWCS-BMC300MX-2","price":272.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381382217818,"sku":"BWCS-BMC300MX-3","price":304.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BMC300MX-1.webp?v=1778900493","url":"https:\/\/batteryweb.com\/products\/biomedical-prt4467-replacement-battery-72v-10000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
