1. No-load voltage. No-load voltage refers to the voltage when the charger is connected to the power supply and the output terminal is not connected to the battery. It should be noted that the no-load voltage of some original chargers is 0v, that is, in no-load There is no voltage output in the state and measurement is impossible.
2. Constant voltage load voltage. The load voltage refers to the voltage at both ends of the battery when the charger is charging normally, but the voltage value changes when the current voltage of the battery continues to rise to the constant voltage charging state.
