These portable ECG units use a single internal pack to power acquisition, display, and transmission functions. Voltage and form factor match OEM part numbers HYLB-727, M21R-064114, TWSLB-004, and 21.21.064146.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSE-12, SE-601, and SE-1202 compatibility:\u003c\/strong\u003e\n    All three models share the same 14.4V battery bay, connector pinout, and BMS communication protocol. The charge IC in each unit expects the same thermistor response and cell-ID handshake, so one pack covers the full platform.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and load cycles on an SE-12 unit. The BMS accepted the cell profile without fault flags, and the charge IC reached full termination voltage without triggering a protection cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test requirement:\u003c\/strong\u003e\n    After installing this battery, allow the device to complete its full power-on self-test without interruption. The ECG's BMS runs a verification routine at startup — cutting power mid-sequence logs a false battery fault 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\"\u003eSE-12 not completing boot sequence after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe SE-12 runs a hardware self-test during every boot that includes a BMS handshake with the installed pack. A new cell that hasn't completed one full charge-discharge cycle may return a state-of-health value outside the expected window, causing the device to stall at the initialisation screen. This isn't a defective battery — it's the charge IC applying conservative thresholds to an uncharacterised cell. Charge the pack fully, power on the device, and let it run through one complete clinical-load discharge before relying on it for patient use.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator stalls below 100% on the first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe SE-12's charge IC uses a current-taper cutoff — it terminates the charge cycle when current drops to roughly 3% of the C-rate, not on a fixed timer. With a new cell, internal impedance is slightly elevated, so the taper threshold is reached before the pack reaches full capacity. The display may hold at 95–98% and stop climbing. One full cycle normalises cell impedance and the subsequent charge typically reaches 100%. If the indicator still stalls after three full cycles, check that the pack is seated fully and the terminal voltage at the connector reads at least 16.4V at charge termination.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381506113626,"sku":"BWCS-EDS601MD-1","price":73.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381506146394,"sku":"BWCS-EDS601MD-2","price":85.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381506179162,"sku":"BWCS-EDS601MD-3","price":94.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-EDS601MD-1.webp?v=1778901305","url":"https:\/\/batteryweb.com\/products\/edan-se-12-replacement-battery-144v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
