SF200 is a precision battery performance test instrument integrated with charge & discharge, auto-cycle detection, it can set the voltage and current of charge and discharge by the user, and has automatic charging and discharging cycle function, the max. cycle number is up to 50 times. The instrument provides 7 work modes for easy operation. SF200 is a precision test instrument for battery manufacturers, electric vehicle manufacturers, and its dealers to process the battery test, regular maintenance, and after-sale service.

It's an essential instrument for battery performance testing & scheduled maintenance to prolong the service life of the batteries.

A number of SF200 modules can be assembled into a testing system to meet the needs of mass testing.

Battery Charge Discharge Testing System

Applicable Batteries:
6V/8V/12V/16V/18V Lead-acid batteries, recommended capacity:<65 AH.


- Instrument displays by LCD, each index is clear at a glance.
- The parameter setup and parameter switching are set and switched by a “START” switch and a “SET” knob. All parameters(voltage, current, mode) setting have the saving function.
- Intelligent speed fan can run continuously, delay the power-off of the fan, and blow-off the remaining heat.
- Polarity protection, anti-reverse connection, and so on.
- Each circuit is the independent module, no influence each other
- The instrument have simple mode and professional mode for choice to meet the different requirement of the user.
- Data protection startup: If the connection cables disconnected from the battery during the charging and discharging, after reconnecting the cables with the battery, press and hold the “Start” button to continue working.
- Power-off memory function.
