How do batteries store energy?
You flip a switch and your flashlight clicks on. You press a button and your phone wakes up. Something inside is ready — holding energy like a coiled spring, waiting to be released. That something is a battery. But how does a battery hold onto energy without letting it leak away?
Energy can't just sit still by itself — it needs to be locked in something. Batteries lock energy in a chemical arrangement, like storing potential energy by separating two things that badly want to come together. Imagine pulling apart two magnets and holding them separated. Your muscles are doing work, storing energy in that separation. The moment you let go, they'll snap together and release it.
