Battery C-1 
Appendix C  Battery 
The battery is inside the machine; only technical 
professionals from Mindray or engineers authorized by 
Mindray after training can perform battery installation and 
uninstallation. 
If you need to change the battery or buy a new one, please 
contact your sales representative. 
C.1  Overview 
The built-in battery is an option. 
When the system is working, the battery charges when its capacity is not full, and the indicator turns 
green when the capacity is full. 
Generally, a completely discharged battery will fully charge in less than 8 hours. 
 
Power off the system if you will not use the system for a long period of time (including storage/ 
transportation condition), and you should not allow the system in standby status, otherwise the 
batteries will be out of power and permanently damaged. 
The battery cannot support the ultrasound system for normal working, but only standby function. 
When you need to move the ultrasound system in a hurry, you can first make the system enter the 
standby mode, pull off the power plug to power the machine in standby status when moving the 
machine, and then press the power button to exit standby after you move the machine to the target 
position and connect the AC power.   
 
C.2  Battery Status Indicator

capacity. 
  : Indicates the battery capacity is nearly empty. 
  : Indicates the battery capacity is full.
