These monitors run continuous vital signs acquisition — ECG, SpO2, NIBP — and depend on a stable battery rail to sustain both the display and sensor modules. Voltage and capacity match the OEM specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCM100 and CM300 platform compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay format, 14.4V nominal rail, and BMS handshake protocol. The connector and cell configuration are identical across the two monitor variants, so a single replacement cell covers both units.\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 discharge on the CM100 platform. The BMS accepted the cell without fault flags, completed charge termination at the correct cutoff voltage, and passed the monitor's internal battery status check on the second full cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After installation, let the monitor complete its full power-on self-test without interruption. The CM100 runs a BMS verification sequence at startup — cutting power during this sequence logs a battery fault that persists until the next clean reboot, even if the cell is fully charged.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCM100 not completing boot sequence after battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe CM100 runs a sequential self-test at power-on that includes a battery state check against stored BMS thresholds. A new cell that hasn't completed one full charge-discharge cycle may report a state-of-charge value the monitor's charge IC treats as out-of-range, stalling the boot sequence. This is a BMS calibration issue, not a faulty battery. Charge the replacement cell to full, run the monitor through one complete discharge, then recharge to 100% — the boot sequence completes normally after that first cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator stuck below 100% on the first charge after installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge, the CM100's charge IC applies a conservative current limit to an unrecognised cell — it doesn't yet have a capacity baseline. The indicator stalls between 85% and 95% because the IC is holding back until voltage stabilises at the top-of-charge threshold. This is normal behaviour and clears after one full cycle. If the indicator still won't reach 100% after two full charge cycles, measure cell voltage at the battery terminals — a healthy cell should read between 16.6V and 16.8V at full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381450702938,"sku":"BWCS-CMA100MD-1","price":59.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381450735706,"sku":"BWCS-CMA100MD-2","price":70.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381450768474,"sku":"BWCS-CMA100MD-3","price":78.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CMA100MD-1.webp?v=1778900876","url":"https:\/\/batteryweb.com\/products\/comen-cm100-replacement-battery-144v-1100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
