Some states in the USA (Currently Maine ME, Connecticut CT, Rhode Island RI, and Louisiana LA, Wisconsin WI, Illinois IL ) require all hearing aid batteries to be completely free of mercury.

Mercury is used as a trace element in button cell batteries, but this metal is considered a hazardous metal and is toxic to the environment when disposed into our garbage dumps.

The hearing aid batteries in this category are in stock and available for purchase.

Residents of these states should purchase mercury free brands to comply with their local regulations.
