Original COMEN C50 Patient Monitor Battery 11.1V 5.2Ah 57.72Wh Lithium-Ion Medical Equipment Battery

Q1: While transporting a patient by ambulance, the monitor suddenly displays "Battery Low," but the hospital is still 20 minutes away. What should I do?

A1: You can use the "Reducing Power Consumption to Extend Battery Life" feature as an emergency measure. Disable non-essential monitoring parameters, such as temporarily stopping automatic non-invasive blood pressure measurement and reducing screen brightness to 30%. If there are no backup batteries, prioritize heart rate and blood oxygen monitoring, closely monitor the patient's consciousness and respiratory status, and contact the hospital's emergency department to prepare for the patient's arrival. This will minimize the time it takes to connect data after transport.

Q2: After the battery is fully charged, the monitor displays "Battery Health 75%" when installed and in use. Does this indicate a battery failure?

A2: "Battery Health 75%" does not indicate a failure; it is a normal indicator of natural battery capacity degradation. This battery is designed for 350 cycles. After about a year of use, the health level will drop from 100% to 80-75%. As long as the battery life still meets basic clinical needs, it does not need to be replaced.

Q3: I'm using the Coman C50 monitor charger to charge this battery, but the charger indicator light isn't on and the battery won't charge. Is the battery damaged?

A3: This is most likely due to charger incompatibility, not battery damage. This battery requires the original C30 charger (12.6V DC/1.5A output), while the C50 monitor charger outputs 14.8V DC/2A. The voltage, current, and interface protocols differ. We recommend replacing the original C30 charger and trying again. If charging still fails, check the battery connector for cleanliness or damage.
