It also fits the Cardio Touch 3000, Cardio 7 ECG Monitor, and Cardiocare 2000 ECG Monitor. Voltage and capacity match the OEM specification at 12V and 48Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCardioCare and Cardio Touch platform fit:\u003c\/strong\u003e\n    These models share the same 12V battery rail, physical form factor, and BMS communication protocol. The connector and cell configuration are identical across the listed devices, so one replacement covers the full family without modification.\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 discharge on the CardioCare 2000 platform. The BMS accepted the cell, completed its initialisation handshake, and the device cleared the power-on self-test without fault codes on the second full cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap startup protocol:\u003c\/strong\u003e\n    After installing this battery, let the CardioCare 2000 complete its full power-on self-test without interruption. The device BMS runs a chemistry verification at startup — cutting power during that sequence triggers a battery fault flag that will persist until the next complete 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 CardioCare 2000 flags a battery fault on the first charge cycle\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe CardioCare 2000 charge IC applies a conservative acceptance threshold on unrecognised or new cells. On the first charge, the BMS compares the incoming cell's internal resistance and charge acceptance curve against stored OEM parameters. A fresh Ni-MH cell hasn't yet settled into its rated profile, so the reading can fall outside the expected window. Running one complete charge-discharge cycle lets the cell stabilise and allows the BMS to update its reference values. After that cycle, the fault flag clears and the charge indicator reads normally.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCardioCare 2000 powering off mid-monitoring session in first week of use\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNew Ni-MH cells carry a slight voltage sag under the load profile of continuous ECG acquisition and display backlight draw before they fully condition. The device's undervoltage cutoff is calibrated for a fully conditioned cell, so a new battery hitting that sag in the first few cycles can trigger an unexpected shutdown. This is not a defective battery — it corrects itself within 5 to 10 charge-discharge cycles as the cells reach full capacity. To reduce the risk during that break-in period, avoid running the device to cutoff; top up the charge when the indicator drops below the halfway mark.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381493563482,"sku":"BWCS-BCC200MD-1","price":82.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381493596250,"sku":"BWCS-BCC200MD-2","price":96.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381493629018,"sku":"BWCS-BCC200MD-3","price":107.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BCC200MD-1.webp?v=1778901249","url":"https:\/\/batteryweb.com\/products\/bionet-cardiocare-2000-replacement-battery-12v-4000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
