Are the devices disposable after the battery runs out? How do you dispose of them?

What to do when the devices are dead?

The content of the devices is not dangerous and is RoHs compliant. By using long life, very small batteries and by having ultra low consumption we are saving a lot of environmental stress by not using replaceable batteries. Due to the size we are using minimal plastics.


If you need to dispose of the device, please dispose of them properly according to your local legislation as with any other electronic devices at collection points.


We are actively researching how to further lower the environmental impact.


For USA regulations:

Li/MnO2 (Lithium/Manganese Dioxide) batteries are United States Resource Conservation and Recovery Act (RCRA) non-hazardous waste. 

Waste Li/MnO2 batteries meet the United States Federal definition of a solid waste per 40 Code of Federal Regulations (CFR) 261.2. 

As such, the generator must make certain determinations relative to the waste material. Waste Li/MnO2 batteries do not fall under any of the specific United States Federal RCRA F, K, P, or U lists, nor do any states specifically regulate this type of waste, to our knowledge. This leads us to the RCRA characteristic waste criteria. 

Toxicity Characteristic Leaching Procedure (TCLP) listed materials are not used as battery components and may only be present in trace quantities in some of the battery parts. Based on our knowledge of the battery and battery raw materials, waste Li/MnO2 batteries are not RCRA toxic. Only the characteristics of ignitability, corrosivity, and reactivity remain as possible classifications.

The batteries are solid, not liquid, which precludes their being a corrosive waste, since corrosive waste must be liquid by definition. As an inert solid, flash point is not an appropriate test for ignitability. Our batteries are a safe consumer product and, under standard temperature and pressure conditions, will not cause fire through friction, absorption of moisture, or spontaneous chemical changes. 

The batteries contain no sulfides or cyanides, and they do not meet any other reactivity criteria, including the criterion "reacts violently with water." An intact scrap battery will not react in that manner.
