Our Hearing Aid Bank recycles hearing aids and along with the aids that are donated to us we receive a fair number of unused but out of date batteries. Do you know of any agency that recycles batteries and would buy them from us?

Tom,
As the article mentions, Zinc-Air batteries are air-activated meaning that once you remove that tab they start to work. You cannot switch them off.

Even though you’re only running them in your aid a few times, they will continue to drain to 0.

Battery life depends on many things, but certainly a couple of weeks is very good performance for the size 312.

Thanks

How long can I expect a size 312 zinc-air battery to last once the tab has been removed if the battery isn’t being used but is just sitting on the shelf? The problem I’m running into is that I use my hearing aids only 2 or 3 evenings each week, and I remove the batteries from the hearing aids between uses, but the batteries are dying within a couple of weeks.

thanks,
