COMEN Patient Monitor Replacement Battery CMLI2X3I002B 10.95V

COMEN Patient Monitor — 10.95V Li-ion Replacement Battery (CMLI2X3I002B)

This 10.95V, 5500mAh (60.23Wh) Li-ion battery replaces the CMLI2X3I002B cell used in COMEN patient monitoring devices. It fits the COMEN Patient Monitor series used in clinical environments for continuous vital signs tracking. Voltage and capacity match OEM specifications exactly.

• COMEN Patient Monitor platform: COMEN monitoring devices share a common battery bay and BMS handshake protocol across this series. The 10.95V three-cell configuration powers the display, sensors, and alarm circuits simultaneously — voltage tolerance is tight, and the BMS will reject cells outside its accepted range.
• Bench tested on actual hardware: We cycled this battery through a full charge-discharge sequence and confirmed the BMS handshake completes without fault flags. The protection circuit responded correctly to load transitions between low-draw standby and the higher-draw alarm and display states.
• Post-swap self-test protocol: After installing this battery, allow the COMEN monitor to complete its full power-on self-test without interruption. The device runs a BMS verification sequence at startup — cutting power during this window triggers a false battery fault that latches until the next complete reboot cycle.

Why the COMEN monitor alarms low battery immediately after a confirmed full charge

The COMEN BMS compares the cell's reported state-of-charge against a stored threshold calibrated to the OEM chemistry profile. A new replacement cell has not yet completed the learn cycle the BMS uses to build an accurate charge map. On the first one or two cycles, the BMS may read the cell as below threshold even when it is physically full. Running one complete charge-to-discharge cycle allows the BMS to recalibrate its capacity estimate. After that cycle, the low-battery alarm should clear and charge reporting should stabilise.

COMEN monitor fails to power on after the replacement battery sat in storage

Li-ion cells self-discharge during storage — if the cell voltage dropped below approximately 2.5V per cell (7.5V total for this 3S pack), the BMS enters deep-discharge lockout and will not pass current to the device. The monitor will show no response even when connected to mains charge. Place the battery on charge via the monitor's AC input and leave it connected for a minimum of two hours before attempting to power on — the charge IC applies a low-current recovery charge below the BMS trip point, and the pack will begin accepting a normal charge rate once cell voltage climbs back above 3.0V per cell.
