A few threads have gone this direction lately and to much debate on the use of AA batteries.

I have not jumped into the world of rechargeable batteries or designer types, specifically in AA. A brick of coppertop Energizers are just to darn cheap at Costco. I now obviously see a need for something better so would like feedback on what works and what doesn't. For comparative purposes lets use flashlights, digital cameras and radios as our power draw.

In your opinions what are the best rechargeables, lithium, NiMh(?) or whatever this battery neophyte is missing to list. Also if discussing rechargeable batteries what unit works best, if any to do so, solar, wall outlet, etc.

I have a solar panel that recharges AA's but not used it yet. And a 'survival' radio that uses rechargeable batteries and a hand crank. I have avoided the "charge your cell phone with AA's" so far, hoping the solar charger would do that better but, I haven't soldered the USB connection yet.

What 'designer AA batteries' should I avoid as well.
