These are brand new tools.

Supports 6v/12v/24v - CCA IEC EN DIN JIS

Test car load state directly.
Test car starting voltage.
Test car charging voltage normally or not.
Low frequency signal testing without external large load discharge test.
Easily read out electrical capacity and physical condition to estimate lifecycle.
Directly detect on the car without removing the battery.
Continuous operation,fully protected overvoltage and reverse connection protection.
Battery test:cold starting current,battery internal resistance and voltage,lifecycle analysis.Starting test:battery 
changing status during system starting.System test:output state during charging system working.
Maximum load test:battery maximum load state.
