It fits the internal battery bay on both portable ECG units and uses the same cell configuration as the OEM pack. Also cross-references part numbers GPRHC222N056, 80608069, and GP220AAH10WMX2.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eECG200L and ECG200S compatibility:\u003c\/strong\u003e\n    Both units share the same 12V battery bay, connector pinout, and BMS handshake protocol. One replacement SKU covers either model — no hardware modification required.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the ECG200L's charge IC and confirmed the BMS accepted the cell chemistry without triggering a fault. Charge termination behaviour matched OEM thresholds after the first full cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, let the ECG200L or ECG200S complete its full power-on self-test without interruption. The device BMS runs a voltage verification at startup — cutting power during this sequence logs a battery fault 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\"\u003eECG200L not completing boot sequence after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe ECG200L runs a BMS learn cycle during its first few boot sequences with a new cell. A fresh Ni-MH pack straight from packaging sits at a resting voltage that can fall slightly below the device's boot-confidence threshold — particularly after storage. If the unit stalls mid-boot, connect it to mains power and allow it to charge uninterrupted for a full cycle before attempting battery-only operation. The BMS recalibrates its capacity estimate after one complete charge-discharge pass, and normal boot behaviour typically resumes from the second cycle onward.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm triggers immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the ECG200L's battery monitor compares cell voltage against a reference table calibrated to a conditioned OEM pack. A new replacement cell holds a slightly different voltage curve until it has completed one full charge-discharge cycle, so the device reads it as below threshold even when the charge indicator shows full. Run one complete cycle — full charge, then use the device until it prompts for charge again — before trusting the battery indicator in clinical use. After that cycle, the voltage curve aligns and the alarm clears at the correct state of charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381403484250,"sku":"BWCS-CAR200MD-1","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381403517018,"sku":"BWCS-CAR200MD-2","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381403549786,"sku":"BWCS-CAR200MD-3","price":70.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CAR200MD-1.webp?v=1778900597","url":"https:\/\/batteryweb.com\/products\/cardioline-ecg200l-replacement-battery-12v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
