Looking for the Best Brand of Battery for Hearing Aids

Hearing Aid Batteries

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.

Where I live, we get given Rayovac and Power One batteries.

new ones are better than old ones, other then that, they are all about the same.

So, size 13? Do you have any Costco stores there? If so, go with KIRKLAND brand.

FWIW, I get over a week on Phonak Nadia Link M with Sz 30 Kirkland (Costco) batteries.

PowerOne and Rayovac are both good hearing aid battery brands, either of them can be as long as it’s convenient for you.
