It uses OEM part number DJDB2600 and matches the connector, voltage rail, and BMS handshake of the original cell. Intended for clinical and portable cardiac monitoring environments where unplanned downtime is not acceptable.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eECG-1230S and ECG-1230T compatibility:\u003c\/strong\u003e\n    Both models share the same 14.4V battery bay, connector pinout, and BMS communication protocol — this cell satisfies the handshake requirements on both units without firmware intervention.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge, standby, and active ECG recording loads. The BMS passed protection thresholds at both ends — no false overcurrent trips under the device's acquisition burst draw and no premature cutoff at low state of charge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap startup routine:\u003c\/strong\u003e\n    After fitting this battery, allow the ECG unit to complete its full power-on self-test without interruption. The device runs a BMS verification sequence at boot — cutting power mid-sequence registers 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\"\u003eDevice not completing boot sequence after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe ECG-1230S runs a multi-stage self-test at power-on that includes a BMS capacity check against a stored threshold. A new cell that has not completed its first full charge-discharge cycle may report state-of-charge data the device considers out of range. This is not a fault in the battery — it is the BMS learn cycle not yet finished. Run one complete charge to full, then discharge through normal use, before treating any boot failure as a hardware fault.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn a new cell, the ECG unit's charge IC applies a conservative current limit until it has profiled the cell's internal resistance. This typically holds the reported charge percentage below 100% for the first one or two cycles, even when the cell is physically near full. The device is not malfunctioning — the charge IC is calibrating. After the second full charge cycle, the indicator will read accurately. Confirm the cell voltage reads between 16.4V and 16.8V at the battery terminals to verify a true full charge state.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381439955034,"sku":"BWCS-ECG123MD-1","price":49.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381439987802,"sku":"BWCS-ECG123MD-2","price":57.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381440020570,"sku":"BWCS-ECG123MD-3","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ECG123MD-1.webp?v=1778900838","url":"https:\/\/batteryweb.com\/products\/cmics-ecg-1230s-replacement-battery-144v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
