6 FAQs about [The current decreases when the battery is charging]

Why does the charging current decrease when charging a battery?

So as charging continues at a constant voltage, the charging current decreases due to the decreasing potential difference between the charger-output voltage and the battery terminal voltage as the battery charges. Expressed differently, the charging current is highest at the beginning of the charge cycle and lowest at the end of the charge cycle.
