To recharge a 37v lithium-ion battery a battery charger, Ask an Expert

Academics

To recharge a 3.7V Lithium-ion battery, a battery charger must move 1320 mAxh of charge from the negative terminal to the positive terminal. How much work is done by the charger? Hint: This is not a capacitor! Convert mAxh to C first. (I don't know how to do this).
