Thanks, @Deaf_piper . That’s good to know that a 675P can last a couple of days. There has been the occasional time that our power has been knocked out for lengthy periods due to inclement weather, and I wondered how long I could expect to get out of disposable batteries. When our world rights itself, I would like to resume travel before I am too old, and disposables would be useful should I find myself sitting overlong in an airport. Interestingly, I have discovered that I use far less power in my rechargeable batteries when I stream, than when I listen to music, podcasts etc. acoustically. My audiologist confirmed that this is true. However, being bimodal, I like the balance that my hearing aid provides and I also like to keep that ear stimulated. Having received my implant during Covid, I am living a very quiet life as well, and also getting about 14 hours from a medium rechargeable. It will be interesting to see how long they will last when I resume a more active social life outside the confines of my home! Cheers!
