how to charge a battery. this is an interesting question.... hmmm. well mr. g explained this, and it is long and complicated. so we better start soon!
a battery is a thing that STORES energy. the energy is called
STORED CHEMICAL ENERGY. this is an important phrase. i actually have no idea why, but mr. g said it was, so..... yeah.
so the stuff is inside the battery can convert to electric energy, and eventually to heat and light energy(which is what a lightbulb gives out.) so what do you do when the battery runs out of energy? HAHAHA! i know and YOU dont! but i will TELL you because mr. g said i had to. blah. well the charger goes ZZZWWWOOOOOOOOOOOOOOOOOOP!! and it does stuff thet makes me feel scienc-y. like charging positive electrolyte. and other technical stuff. well pretty mach it just charges that electrolyte solution so it has more power in it. and thats about it. the end!
