to recharge them without buying the rechargeable batteries instead? The regulare AA's are 1.5v where the rechargeable AA's are only 1.2v so you are losing out. I heard years ago something along the lines of wrapping them in foil and putting in the freezer. Anyone heard this?

Take a good look at your batteries. I'm sure they have a warning not to recharge them. There is a good reason for that. The chemical reaction in regular batteries is ONE WAY. Once the chemicals are used up there is no way to restore it. Trying to recharge them will only cause you grief. Replace them when they die or consider rechargeables.
Most devices that use AA batteries will work just fine with rechargeables even though the battery voltage is a bit lower. In fact, regular battery voltages drop too so they may start at 1.5 volts but end up closer to 1 volt when they die. Unless you're using the batteries to power something you use only once in a while - like a flashlight, I'd go with rechargeables myself

I knew someone wrapped them in foil. Ran the batteries down. I never laughed so hard.
Years ago, you can charge them up.
Now, the companies made them so you can't charge them.

no but you can smash them (seriously) and it gives them a little boost and they work longer.
