There are many types of consumer batteries, from the lead-acid batteries we use in our cars to the little button batteries in our watches. There are household batteries like AA, AAA, C, D and 9-volt, some of them rechargeable, some not. But whatever type of battery, they all have chemicals inside them.
Of course, chemicals are not all equally toxic. The 3 worst "baddies" in batteryland are:
Other battery compounds like silver, zinc, and nickel can also be problems, but less so.
Sending any type of battery to the landfill or incinerator means the contents of the battery will ultimately end up getting into the soil, air, groundwater, and/or surface water, and thus eventually into the food chain and drinking-water supply. Thus, the key thing is to make sure batteries with toxic components do not go to the landfill or incinerator in the first place.
Contact your county or municipal government to determine how best to dispose of them.
