The secondary battery was designed so that it would not become overcharged even when being charged. However, this charging circuit has drawbacks such as not only it taking a long time to fully charge the secondary battery, but also power loss due to resistance and the output of the expensive solar cell not being effectively utilized. Note that 3 indicates a backflow prevention diode.
