As the title, I wonder if it is safe to use disposable hearing aids batteries after their expiry date?
And for how long can you still use them after their expiry date?
I’ve got a box of 60x 675 batteries that expired in Sep 2023, so not sure if I can safely use them or discard them?
As it seems difficult to find disposable batteries with long shelf life at the moment, my last brand new 675 I’ve got last month (puretone.net) will expire in March 2025, way shorter than the standard 4 years shelf life.
Thx
