The AR600 is a portable cardiac monitoring device used in clinical and ambulatory settings for heart rhythm recording. This battery restores field power to the unit when the original cell has degraded through repeated charge cycles.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAR600 platform compatibility:\u003c\/strong\u003e\n    The Cardiette AR600 runs a 9.6V Ni-MH architecture with a BMS that handshakes at startup to verify cell chemistry and state of charge. A Li-ion or NiCd swap at this voltage rail will trigger a persistent battery fault — Ni-MH is the correct chemistry for this platform.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the AR600 BMS verification sequence. The charge controller accepted the cell on first connection, and the BMS completed its state-of-charge calibration after one full charge-discharge cycle without triggering a fault flag.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, allow the AR600 to complete its full power-on self-test without interruption. The device runs a BMS verification at startup — cutting power during this sequence causes a false battery fault that persists until the next clean reboot cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAR600 not completing boot sequence on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe AR600 runs a BMS learn cycle at first boot with a new cell. If the battery sat in storage before installation, self-discharge may have pulled the cell below the BMS recovery threshold — typically around 8.5V on a 9.6V Ni-MH pack. At that voltage, the charge controller enters a trickle pre-charge phase rather than full charge, and the device may stall partway through boot. Connect the unit to mains power and allow a full uninterrupted charge before attempting to power on again.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAR600 alarming low battery immediately after a full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS threshold issue, not a cell fault. The AR600's charge IC applies OEM-calibrated thresholds, and a new cell that has not completed a full charge-discharge cycle may read below those thresholds on first use. The BMS has not yet mapped the cell's actual capacity curve. Run one complete charge-discharge cycle on the device before clinical use — after that cycle, the alarm should clear and the charge indicator should read correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381493137498,"sku":"BWCS-CAG600MD-1","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381493170266,"sku":"BWCS-CAG600MD-2","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381493203034,"sku":"BWCS-CAG600MD-3","price":58.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CAG600MD-1.webp?v=1778901248","url":"https:\/\/batteryweb.com\/products\/colson-ecg-cardiette-ar600-replacement-battery-96v-2500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
