How will i know if the AAA batteries OR the silver oxide battery need a replacement?

Is there a different message for each of the above scenarios?

Also, how frequently do you replace the silver oxide battery?

How do we know when we need to change it? Do you do it on your own or get it done in a shop (screw , etc)…

Thanks so much
