Lithium battery Charging requirements specifically support the form of lithium battery charger, usually in the charger packaging is marked. Many chargers compatible with the two forms of charging, when you choose to pay attention to the active identification is still manual switch settings, if it is manually set, it is necessary to set the type of charging pool correctly. For Ni-cd/Ni-MH battery, the excellent charger adopts the charging method with negative pulse charging, which can reduce the polarization effect during the charging process. The usual charge for the sale of the charger is constant current. The battery charge waveform depends on the oscilloscope talent accurate investigation.
