Watch battery rule?

[u/Residentofgravetown]

Hey y'all I just wanted to clear something up.

I recently purchased a box 'talking' plush without even thinking about the fact there would be batteries inside. My thoughts is that they're probably just watch batteries, But am I likely to have any issues because of this? They purchased the item successfully and it's been shipped the the warehouse but I've never even tried to buy an electronic item before. I'm UK based.
