It matches the OEM part numbers 120236 and BATT\/110236. Voltage, capacity, and connector are matched to factory specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAR600ADV and AR600 compatibility:\u003c\/strong\u003e\n    Both recorders run the same 9.6V battery rail with identical connector and BMS handshake. The cell count, voltage steps, and pack geometry are shared across the two model variants, so one replacement cell fits both.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on a Ni-MH compatible charger and monitored BMS response at each voltage step. The protection circuit engaged correctly at both low-cell and overcharge thresholds, and charge termination triggered at full capacity.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, allow the AR600ADV to complete its full power-on self-test without interruption. The device runs a BMS verification sequence at startup — cutting power during this window registers 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\"\u003eWhy the AR600ADV may not complete its boot sequence on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe AR600ADV runs a startup verification pass that checks cell voltage against a stored BMS threshold. A new Ni-MH cell fresh from storage often sits below this threshold even when the pack reads charged, because surface charge and resting voltage differ in Ni-MH chemistry. The device interprets this as a depleted or faulty battery and halts the boot. One full charge-discharge cycle normalises resting voltage and clears the condition.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on the first charge after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn a new Ni-MH cell, the AR600ADV charge controller applies a conservative current limit on the first cycle. This is a deliberate behaviour — the charge IC cannot yet predict the cell's heat and voltage response curve, so it terminates early. The pack is not defective. Run a full discharge to the device's low-battery cutoff, then recharge completely — the indicator will reach 100% from the second cycle onward. Resting voltage after a complete cycle should read approximately 9.6V at the pack terminals.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381493006426,"sku":"BWCS-CAG600MD-1","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381493039194,"sku":"BWCS-CAG600MD-2","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381493071962,"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\/cardiette-ecg-recorder-ar600adv-replacement-battery-96v-2500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
