I am trying out Starkey Genesis A24 rechargeable. I have never worn any before so it is difficult to compare with disposable batteries. However, let me share my experience with other wearables as it influenced me to choose rechargeable. I have been using a rechargeable watch for several years and there has never been a problem with either the charger or the watch itself. Of course, the battery life is degrading as the time goes by. Ear buds is another example.
My Starkey HA batteries are good for two days so I have plenty of room to handle any future degradation. My hearing loss is mild so I can get away with a short interruption. My HAs also warn me in my ears when the battery life reaches 10 per cent. This is a great feature.
So far the weak link with my HAs is not the HAs but the charger which has been failing to charge one of the HAs occasionally because of the slotting issue. They have given me a new charger but there is no doubt that where either the rechargeable or charger fail, you need to have a plan B in case you have serious hearing loss. I believe that in the future they might introduce a super tiny magnetic emergency battery pack hugging the HAs (example, iPhone).
Another reason I bought the rechargeable is that they are known to be waterproof as they do not contain a slot for disposable batteries. The other day, I received heavy rain on my HAs and there was no worry. I have been told that my hearing aids are covered for battery replacements but it is not crystal clear.

Spare aids, check, spare batteries, check, secondary spare batteries, check, , check, spare ALD, check, charging brick for ALD’s, check, all these get packed before anything else, I kid you not!
I think because of our loss, we are natural worriers, so much so, future hearing aid development is a big part of our lives & interest, and the apparent lack of BTE UP’s with 675 batteries under development, also has us worried… At present, only Phonak with their Naida Lumity BTE UP’s, are the only new game in town, a Cros version of this would be most welcome in the not too distant future! Oticon Xceed, is coming up on 5 years since its release, in relative terms, it’s old hat! I would say, most UP users, will be worried about the future, we see at present, more and more development of rechargeable aids, and less, and less BTE UP’s, with replaceable batteries options being made available, I don’t think these worries are misplaced? This might be the primary reason for any angst on this thread or others like it? As always, YMMV… Cheers Kev 
I was going to try these 675 batteries on my Naida Lumity’s, perhaps my next purchase of batteries, in a few months? I might get a couple of days longer runtime? They are slightly more expensive than the ordinary 675’s, not that I am bothered with the price though, around 13 days runtime with the ordinary batteries… Thank you for the reply. Cheers Kev
