HCF3 series charging and discharging machine: suitable for charging and discharging various acidic and alkaline batteries; Adopting microcomputer technology, equipped with LCD liquid crystal display screen, fully displaying in Chinese; Not only does it have a complete human-machine interface, easy operation, clear and easy to understand display, but it also has powerful functions, integrating multiple working modes such as charging, discharging, and cycling charging and discharging.

Charging working mode:
Using constant current and constant voltage control method for operation; The entire charging process is divided into two stages: constant current and constant voltage. In the initial stage, the battery has a strong acceptance capacity and is charged with a large constant current. In the later stage, the acceptance capacity of the battery weakens and it automatically switches to constant voltage charging. The charging voltage remains unchanged, and the charging current gradually decreases as the battery charging amount increases.  

Discharge working mode:
Using constant current control mode for operation; During the entire discharge process of the battery, the discharge current remains constant; And it discharges into high-power resistors without polluting the power grid;  
Charging and discharging cycle working mode:
The above charging and discharging methods are used for operation, and automatic switching between charging and discharging is achieved, as well as allowing users to set the number of cycles for charging and discharging. Provide convenience for users in initial charging, maintenance, and upkeep of batteries.

Complete equipment functions:
Comprehensively judge the completion of charging and discharging work using various methods such as voltage method, time method, and capacity method, and automatically shut down;  
It has the functions of automatic detection, delayed start, soft start, and soft shutdown;  
It has fault protection and alarm functions for open circuit, reverse connection, overload, overheating, and power shortage.  
The device has an automatic gear shifting function. In order to improve the efficiency of the charger, the main transformer is divided into multiple outputs and can automatically switch gears according to the voltage of the battery connected by the user, without the need for personnel operation.  
The LCD screen displays real-time working modes, various charging and discharging parameters, and fault information.  
High brightness LED indicates the operating status and fault alarm of the device;  
Automatic shutdown if the charging connection cable falls off during charging;  
The system can remember the parameters set by the user for a long time without losing them even during power outages. After setting the charging and discharging parameters for the first time, if the same battery is charged and discharged in the future, only confirmation is needed each time without resetting;  
Users can set or modify all parameters online during the charging and discharging process.
