In a battery recharger. They basically suck power out of an AC outlet, and store it inside the battery. Rechargeable batteries leak power -- unlike alkaline batteries that hold their charge for years -- rechargeables go dead after a month or two, and need to be recharged again, even if they are not used. There are two types of rechargers: smart -- stops recharging when the battery is recharged. Smart rechargers are usually pretty fast -- some are very fast rechargers. stupid -- keeps recharging until you unplug the recharger. Stupid rechargers are usually slow rechargers -- 100mA/hour... so typical AAA rechargeable battery takes 5 - 8 hours to recharge. Go for smart chargers -- it may be double the price -- but you will be able to get many more recharges out of your batteries. Best to let your batteries completely discharge before recharging. google rechargeable batteries -- there's really a lot more that can be said about rechargeable batteries.

I'll do my best at explaining it for ya. To start, you need to understand how they work in the first place. Theres a chemical reaction going on inside of the battery that produces the electricity. I'm not going to go into all the details involved in this with flowing ions etc. When you put a battery in a recharger, the electricity effectively forces the reaction to reverse, allowing it to happen again, providing more electricity. Eventually the system wears out, and the batteries won't hold a charge or will only last a few minutes.
