Don't buy hearing aids with rechargable battieres. They will slowly last shorter and shorter until you don't have even half a day until you need to charge them over half an hour or longer. They also have a typical runtime of less than a day, even the modern expensive ones. A friend of mine uses hearing aids where the batteries last them about a week until they need to change them, which takes them not even a minute. Batteries cost only a few bucks and are well worth the "empty to full in 1 minute" feature. Plus batteries don't require you to give the whole hearing aid away when the rechargable battery eventually dies.
