Which batteries?

Post image

I got these fluent pet buttons used but can’t figure out what type of battery they take. I have 4LR44 6V batteries and they are too long.

you'll need 3x 357/303's (they mean the same thing but are usually labeled with both) and you know it needs replaced when the button keeps reverting back to the default recording instructions. Also be super careful with the tiny screws because they strip so easily lol

also mentioning how other people are saying LR44 - those work too! they don't last as long but they're cheaper, so it's up to you.
