The disposal of your hearing aid batteries depends on the type of battery that you have. If you have a type that contains no mercury, getting rid it is an effortless task. Mercury-free battery options are safe to be disposed of in household waste. To check if your batteries contain mercury or not, you’ll have to consult the packaging.
If you find that your batteries contain mercury or if the manufacturer did not write “mercury-free” on the package, you should immediately assume that it is not safe to throw in regular garbage containers. To dispose of these batteries you should go to a recycling center that accepts batteries with mercury.
