Looking for the Best Brand of Battery for Hearing Aids

Hi everyone!

I’m looking for the best brand of battery for my hearing aids — Phonak Naida M70-SP.
Today I have only 3 batteries left — I replaced one today. I asked ChatGPT for information about the best batteries for my hearing aids.
The results were:

• Renata
• PowerOne (this brand is not sold in Argentina, but it’s the same as Phonak and the factory is identical)
• Rayovac Extra

The first and third brands are available in Argentina. I am currently using Rayovac Extra but I have some doubts about the brands.
I would appreciate your advice. Maybe this year I will change my hearing aids, possibly to the Audeo Infinio Sphere UP — the first test units will be available soon, between August and September in my country (yes, the bureaucracy is quite big).
Or maybe I should wait for the next Naida Infinio, which is expected to be released between August and October.

Thank you!
Have a nice day!
Best regards.
