What.. alternates by them to recharge the battery? How is it recharging? In a gas car? While its off? I feel like an idiot!

In the old days, they used DC generators but those generators couldn’t output the amount of current that modern cars need to operate everything. Alternators can output a lot of current and do it fairly efficiently. There is a high current rectifier inside the alternator that converts the alternating current into sort of a pulsed direct current that your car needs.
