While the article is about the lithium coin cells, I think hearing aid batteries are an even bigger risk.<p>Given that zinc air batteries last for a week or two in most hearing aids (I use these batteries on active shooting earplugs; they are amazing), it would be great if some store or other facility frequented by users would do the change in person with proper disposal for free.  (Yes, I buy the batteries in bulk to save money, but even with the tabs, I can imagine this being a difficult task for older people with bad eyesight or motor skills to do, so paying a small premium at retail would work.)<p>Doesn&#x27;t work as well for homebound users.  Maybe a battery changing robot which stored the batteries internally, including used ones, for bulk replacement and disposal?  Although a lifetime for a 70 year old of batteries could probably fit in a small enough volume.
