Disposal of Mercury-Containing Button Cell Batteries

Mercury was discontinued from regular alkaline batteries in 1996. Mercury is still used in button cell batteries in the types listed below. Do not place button cell batteries in the regular trash. It is recommended, to place the spent batteries in a sealed childproof container out of reach of children. Batteries are known to be a choking hazard. Contact your local municipality or solid waste district for guidance on disposal of all types of batteries, which some may be considered hazardous for reasons other than mercury content. Some pharmacies, nursing homes, audiologists and hearing aid dispensers offer free recycling.
