Soshine 3.0V batteries have diodes in them. You see, Li-ion chemistry produces 3.6V (nominal) and those Soshines are Li-ion batteries. The diodes are not there for protection. They are there to drop the output voltage from 3.6V (nominal) to 3.0V (nominal). So inside your battery is a charged Li-ion cell that has about 4.2V (full charged state of 3.6V Li-ion). But the power is coming through an output diode (0.6V typical) to drop the voltage to 3.6V (result of regulation) so that it can be put into devices that cant handle the 4.2V.This is the reason that you must use the 3.6V setting to charge them(yenster)
