Comen Rechargeable Li-ion Medical Battery 4800mAh 7.4V 35.52Wh for Long-lasting

Coman battery CMLI2X4I003B, with a nominal capacity of 4800mAh, is primarily suitable for medical devices such as Coman monitors. Its primary function is to provide stable and long-lasting power to ensure continuous operation and data monitoring.

• Battery Life Suitable for Medium to High Loads

  The battery voltage is 7.4V and the energy capacity is 35.52Wh. Under normal power consumption, the battery life can reach 6-7 hours. Under low power consumption, the battery life can be extended to 8-9 hours, covering core scenarios such as a morning of high-frequency examinations in the outpatient clinic and inter-floor transfers within the hospital, without the need for frequent charging.

• Built-in Protection Devices

  Six built-in protection mechanisms for overcharge, over-discharge, short circuit, overtemperature, overcurrent, and balancing prevent battery failure from causing device downtime or parameter monitoring anomalies.

• Low Maintenance Cost

  No memory effect, support on-the-go charging. During daily use, the battery can be recharged at 20% remaining, reducing maintenance costs for medical staff. Furthermore, when the device is plugged into an external power source, it can directly charge the battery, eliminating the need for a dedicated charging device.

• Portable Weight

  The battery weighs only approximately 320g. Combined with the device's lightweight design, it's easy for medical staff to carry with one hand or attach to a transport cart, reducing the burden during medical visits and transports.

Q1: A battery has been stored in a locker at a community health service center and has not been used for four months. After installing the device, it won't turn on. How can I activate it?

A1: First, charge the battery separately and observe the charger indicator. If it changes from solid red to flashing green within 30 minutes, the battery is activating and you should continue charging until fully charged. If the indicator remains solid red after one hour of charging, use a dry cotton swab dipped in a small amount of medical alcohol to wipe the metal contacts where the battery connector meets the device. Let it dry and then reinstall the device. If this doesn't work, the battery cell may be permanently damaged and needs to be replaced.

Q2: The battery case gets slightly warm during charging. Is this a safety risk?

A2: Heating during normal charging is normal and does not pose a safety risk. If the battery becomes excessively hot to the touch, stop charging and contact a repair technician.

Q3: After 16 months of use, the charging time has decreased from 3 hours to 1.5 hours, and the battery life has decreased from 6 hours to 4 hours. What should I do?

A3: This is a normal phenomenon caused by battery capacity degradation. We recommend prioritizing a "capacity calibration": Charge the battery to 100% using a charger. After installing the device, perform five consecutive complete "heart rate + blood oxygen + non-invasive blood pressure" monitoring cycles and record the remaining battery capacity. If the remaining capacity is ≥ 60%, the battery still meets basic monitoring needs and can be used for 1-2 months before recalibration. Otherwise, replace the battery.
