When charging a battery, what determines the charging rate? Is it possible to charge a battery with a charging source that has a lower voltage than the battery you want to charge? Why or why not?

Question

Quizplus · Accepted Answer

The Answer is The charging rate depends on the voltage difference between the battery voltage and the voltage of the charging source. In all instances, the voltage of the charger must be greater than the total battery voltage. If the charger voltage were lower than the battery voltage, the battery would discharge by driving electrons through the charger.
