It replaces the original internal battery in clinical and hospital settings where the Colin 2070 is used for continuous patient vital sign monitoring. Capacity figures are taken from the product data — 47.52Wh total energy at 10.8V nominal.\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 uses a three-cell Li-ion configuration at 10.8V nominal. This battery matches that voltage rail and cell count. The BMS expects a specific charge profile — deviating from that triggers fault flags in the device firmware.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through the Colin 2070's power-on sequence and monitored BMS handshake behaviour. The protection circuit engaged correctly at low-voltage cutoff, and the charge IC accepted a full charge without triggering fault codes on the second cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap startup protocol:\u003c\/strong\u003e\n    After installing this battery, allow the Colin 2070 to complete its full power-on self-test without interruption. Medical device BMS verification runs at startup — cutting power mid-sequence causes a false battery fault flag that persists 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\"\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 was calibrated against the original OEM cell chemistry. A new replacement cell has a slightly different internal resistance profile, and the BMS reads that as a capacity shortfall during its initial self-test. This false alarm typically clears after one complete charge-discharge cycle, which allows the BMS to recalibrate its state-of-charge estimate against the new cell. Do not use the device clinically until that first full cycle is complete and the alarm does not reappear. If the alarm persists after two full cycles, check the battery seating and connector contact before escalating.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eColin 2070 shuts off unexpectedly during patient monitoring\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eUnexpected shutdown during active monitoring is usually a BMS overcurrent trip, not a dead battery. The Colin 2070 draws a sharp current spike when the cuff inflates — new cells in the first ten cycles have slightly elevated internal resistance, which amplifies the voltage sag during that spike and can push the BMS past its cutoff threshold. Letting the battery complete five to ten full charge-discharge cycles before sustained clinical use reduces internal resistance and lowers the sag. If shutdown occurs during cuff inflation specifically, check that the battery is above 11.0V resting voltage before starting a monitoring session.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381400240218,"sku":"BWCS-CKP122MD-1","price":176.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381400272986,"sku":"BWCS-CKP122MD-2","price":210.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381400305754,"sku":"BWCS-CKP122MD-3","price":236.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CKP122MD-1.webp?v=1778900536","url":"https:\/\/batteryweb.com\/products\/medtronic-colin-2070-replacement-battery-108v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
