Am wondering why they don’t just preserve their charge until the next time someone decides to use them.
In: Engineering
Imagine a battery is like a water bottle with a small leak, where a drop leaks every two days. Even if you don’t drink from it, water slowly drips out over time. Similarly, a battery slowly loses its stored energy even when it’s not being used, because of tiny “leaks” in the form of slow chemical reactions inside.
So, even if you leave a battery unused, it will still lose charge because of these unavoidable, natural processes happening inside it
