batteries don't belong in the regular trash (why?). but i've been trying to figure out where/how they can be properly recycled (not in the regular recycling). apparently recycling of rechargeable batteries is common--but household batteries are generally overlooked.
here in LA, it turns out to be simpler than expected! (the state has strict laws about battery disposal.) the city setup a battery recycling program [pdf] with local Targets, Jiffy Lubes, and fabulous B&B hardware. surprisingly convenient!
