Can AG13 LR44 alkaline batteries, SR44 357 silver batteries be interchangeable with 675 PR44 hearing batteries?

In practice, it is not worth installing a hearing (zinc-air) battery, e.g. in watches, remote controls, calculators, toys, where we replace batteries very rarely - e.g. once every few weeks. However, if our device works very briefly on alkaline batteries (e.g. a few hours, or a maximum of a few days), and the battery compartment is not completely tight, the zinc-air battery will provide a significantly longer operating time.

The use of AG13 or SR44 batteries in a hearing aid may also be justified, but only in exceptional circumstances - e.g. in an environment with high humidity (e.g. a swimming pool), where zinc-air batteries do not work optimally. Remember, however, that neither alkaline nor silver batteries are designed for use in hearing aids, sound processors or implants - zinc-air batteries should be used in everyday use.
