Our alkaline batteries are composed primarily of common metals – steel, zinc, and manganese – and do not pose a health or environmental risk during normal use or disposal. We have voluntarily eliminated all of the added mercury from our alkaline batteries since the early 1990s .... Therefore, alkaline batteries can be safely disposed of with normal household waste, everywhere [in the U.S.] but California.
