The zinc-air battery contains a highly conductive potassium hydroxide electrolyte and a zinc anode. When this combination is exposed to air by removing a small sticker from the back of the battery (uncovering a small inlet of holes), it produces electricity for a given length of time. How long the batteries would last would depend on many factors (the level of your hearing loss, environment (altitude), individuals hearing usage etc).
As you will be regularly changing your hearing aid batteries, you may be attempted to toss the batteries into your trash.
While convenient, tossing these tiny batteries into your trash may actually harm the environment.
Batteries and the environment
Zinc air or NiCd batteries found in most hearing aid should never be tossed in with your household trash.
Batteries can leach toxic chemicals (such as cadmium or lead) into the ground, contaminating soil and water. If groundwater is contaminated, it carries the contaminants with it as it moves. This can cause soil and water pollution and endanger wildlife.
Batteries and human health
Nickel is toxic in high doses but the cadmium in rechargeable batteries is one of the most dangerous substances. According to the World Health Organization, cadmium has toxic effects on the kidneys, the skeletal system and the respiratory system. It is classified as a human carcinogen.
Recycling batteries safe energy
But there is another reason to keep batteries out of landfill. The metals in batteries, including zinc, nickel, silver and cadmium, can be recovered and reused.
Using recycled metals from batteries also saves energy. According to the European Union Batteries Directive, using recycled cadmium and nickel requires 46 per cent and 75 per cent less primary energy, respectively, than extracting and refining virgin
Clarisound would like to do their part to reduce the environmental impact of hearing aid batteries by collecting them and sending them to a recycling centre. We are the FIRST hearing aid company in Malaysia to launch a recycle your used hearing aid batteries with us.
You can drop your used hearing aid batteries at any of our Clarisound outlets.
Recycling promotes the “take, make and reuse” circular model that will help to sustain our planet for generations to come.
