Power supply 4.5v can drive 3.6v lithium battery
it is recommended:
1, carefully measure the output voltage of the regulated power supply.
2, if it is 4.5 volts, easy to transform the output can be connected to a "germanium diode" (its forward conduction voltage is 0.2 ~ 0.3V), will make the output voltage is basically reduced to the appropriate.
Because the lithium battery requires a charge termination voltage of 4.2 volts.
If you want to strictly control the charge termination voltage
Can charge. But to the late to be careful, do not overcharge.
