Agreed 100% @prodigyplace… But, I feel the manufacturers would need to play ball, which is perhaps questionable… It’s not in their best interests to increase the longevity of rechargeable aids, and though it might be marginally better for the environment, it doesn’t increase their sales… They want to regulate sales, and much the same as Apple
, they make it difficult to swop out Lifepo4 batteries, by making aids obsolete due to battery degradation… IMO, it’s a win, win, win for the manufacturers, who’s only interest is increased revenue, and that is the bottom line! As always, YMMV… Cheers Kev
