It fits the DECG-03A electrocardiograph and MEC-03 monitor — clinical-grade units used for cardiac recording and patient diagnostics. Capacity is 2600mAh (37.44Wh), matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDECG-03A and MEC-03 compatibility:\u003c\/strong\u003e\n    Both devices share the same 14.4V battery bay, SE-601A connector pinout, and BMS handshake protocol. One cell works across both platforms without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and full-load discharge on ECG-class equipment. The BMS negotiated correctly, reported state-of-charge accurately, and held voltage above the device's low-battery cutoff threshold through the full discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use self-test protocol:\u003c\/strong\u003e\n    After installing this battery, let the device complete its full power-on self-test without interruption. The DECG-03A runs a BMS verification sequence at startup — cutting power mid-sequence writes a fault flag that persists until the next clean boot 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 DECG-03A alarms low battery with a freshly charged replacement installed\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe DECG-03A BMS calibrates state-of-charge against the OEM cell's charge profile. A new replacement cell hasn't completed a learn cycle, so the BMS may read the charge level conservatively and trigger the low-battery threshold prematurely. This is not a cell fault. Run one complete charge-to-discharge cycle — charge fully until the indicator stops, then allow normal discharge during use. After that cycle, the BMS recalibrates and the alarm clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not powering on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge in storage. If the cell voltage drops below approximately 10V, the DECG-03A BMS will refuse to power the device — this is a protection cutoff, not a dead cell. Connect the charger and leave it for at least 60 minutes before attempting to power on. The charge IC applies a low-current recovery charge to bring the cell above the BMS wake-up threshold. Once voltage reaches roughly 12V, the device will boot normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381503754330,"sku":"BWCS-EDS120MD-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381503787098,"sku":"BWCS-EDS120MD-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381503819866,"sku":"BWCS-EDS120MD-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-EDS120MD-1.webp?v=1778901305","url":"https:\/\/batteryweb.com\/products\/mindray-decg-03a-replacement-battery-144v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
