Chitownbarb: while I have only used the manual battery operated aids for 30+ years, I would shy away from rechargeable battery aids - personally! They may work fine for others with a different lifestyle, but not for me.
I travel a lot - to some exotic countries and places where I’m not even sure what the power situation would be. Just getting to these places involves flight times of 20-30 hours. So I’d hesitate to be going to a foreign country with my aids gone DEAD on the flight. Imagine explaining that to a Customs Officer. (I actually had a gal in my tour party that went through that very scenario.)
I like ultimate control over a device that is so absolutely critical to my day-to-day living. For that reason, I would similarly never go the route of Lyric, et al, where the audiologist has you come in every couple of months to change the battery. Have you ever had a brand new battery either DOA or die within a day or so cuz it’s defective? I have. I always travel with spare batteries to last the entire length of a trip PLUS a few extra weeks. You never know if you’ll be caught in a political situation or natural disaster with no access to power charges or buying batteries.
The rechargeable batteries may also wear down over time, too, as most rechargeable devices need to be used till drained, then charged up again. That whole scenario is simply unacceptable to me with my hearing loss - like I’m going to take my aids out in the middle of the day, walk around deaf as a brick for a couple hours while they charge up? Nope.
Again, different folks with different loss profiles & lifestyles than mine may be able to use rechargeable aids with JOY and freedom! But I understand what my limits are, and the yoke I wear on a daily basis that has to be taken into account.
