It also fits the SE-1 ECG and several other Edan clinical devices that share the same battery bay and connector. Cross-reference OEM part numbers 21.21.064149, HYLB-102, or TWSLB-005 to confirm fit before installing.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eM3 and SE-1 series compatibility:\u003c\/strong\u003e\n    These models share a common 14.4V battery architecture, connector pinout, and BMS communication protocol — which is why one cell pack covers both imaging and ECG platforms without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge-discharge cycles on Edan-compatible equipment and confirmed the BMS handshake completes correctly, charge IC accepts the new cell, and no spurious fault codes are thrown during the power-on self-test sequence.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, let the device complete its full power-on self-test without interruption. Medical-grade BMS firmware runs a verification pass at startup — cutting power mid-sequence registers a false battery fault that sticks until the next clean 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 M3 flags a battery fault on a brand-new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe M3's BMS uses a stored charge-history profile to validate battery state at boot. A new cell with no cycle history doesn't match that profile, so the device can flag a fault even when the cell is fully charged. This is not a hardware fault — it's the BMS learning cycle running as intended. One full charge-to-discharge-to-charge cycle typically clears the flag and allows normal clinical operation.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator stalls below 100% on first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge, the M3's charge IC applies a conservative current limit to new cells — this is normal behaviour built into the charging firmware. The indicator can stall at 90–95% for an extended period before completing. Do not interrupt the charge. Leave the device on charge until the indicator confirms full charge, then run one complete discharge cycle before clinical use to calibrate the capacity gauge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381503852634,"sku":"BWCS-EDS120MD-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381503885402,"sku":"BWCS-EDS120MD-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381503918170,"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\/edan-m3-replacement-battery-144v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
