The Colin 2070 is a clinical-grade cardiac monitoring and patient assessment device used at bedside and during patient transport. Voltage and capacity match the original specification so the device's charge management circuit operates within its expected parameters.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eColin 2070 platform fit:\u003c\/strong\u003e\n    The Colin 2070 runs an 11.1V three-cell Li-ion pack with a BMS that validates cell voltage at startup. This replacement uses the same cell configuration and voltage rails, so the monitor's internal charge IC recognises the pack without flagging a battery fault on boot.\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 clinical device test bench. The BMS completed its initialisation handshake, the charge indicator progressed normally, and the protection circuit engaged correctly at the low-voltage cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, allow the Colin 2070 to complete its full power-on self-test without interruption. The device runs a BMS verification sequence at startup — cutting power during this window writes a battery fault flag to memory that persists until the next complete 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 Colin 2070 alarms low battery immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Colin 2070's BMS stores a learned voltage profile for the OEM cell chemistry. A new replacement cell has not yet completed a full charge-discharge cycle, so the monitor's state-of-charge algorithm underestimates remaining capacity and trips the low-battery threshold early. This is a calibration state, not a faulty battery. Run one complete charge-to-discharge-to-full-charge cycle before clinical use. After that cycle, the BMS recalibrates its capacity model and the alarm clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eColin 2070 shuts off unexpectedly during patient assessment in the first week of use\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNew Li-ion cells have slightly elevated internal resistance before they are broken in. The Colin 2070's load profile during active monitoring — screen, wireless, sensors running simultaneously — draws enough current to cause voltage sag on a fresh cell that hasn't completed its first few cycles. The BMS interprets this sag as a low-voltage event and cuts power to protect the cell. The fix is to run five full charge-discharge cycles before relying on the battery in active clinical use. Internal resistance drops after conditioning, and voltage sag under the device's full load stays within the BMS tolerance band.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381398831194,"sku":"BWCS-CKP121MD-1","price":146.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381398863962,"sku":"BWCS-CKP121MD-2","price":174.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381398896730,"sku":"BWCS-CKP121MD-3","price":195.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CKP121MD-1.webp?v=1778900536","url":"https:\/\/batteryweb.com\/products\/medtronic-colin-2070-replacement-battery-111v-2500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
