In science we learned about energy and batteries. We also learned what happens when you charge a battery and when you put batteries in things like TV remotes. When you charge a battery electrical energy comes from the outlet in the wall and into the charger. But when it goes into the charger it turnes into stored chemical energy then goes into the battery. When you plug a battery into something the stored chemical energy from the battery turns into electrical energy and goes through the wires and into the thing you are powering and turns it on.
