I had a variety of AAA, AA, 2/3A, C, D Alkaline/NiMH as well as a few Li-Ion cells, and tried dropping them off at my local electronics store, then Rat Shack, & Best Buy while running errands. None of them would take them. They said the only ones they take are sealed cell phone batteries at Rat Shack. Are there EPA guidelines mandating who must accept them?
