I have no idea of the battery size...probably hearing aid size. You need a small screwdriver to open it. Have had it a year and it is still going strong.

We didn't have a problem with the batteries... I'm not sure the size but they're rectangular in shape. It was a breeze to install

No idea. They were just your standard-sized AAA batteries when I bought them.

They use a common battery, (I believe it was a AAA). They are in my travel bag ready for my next trip.

I can't recall the dimensions, but it was the same size as the conventional lead/acid battery it replaced. Just look up the size on a manufacturer's website.

It had batteries already in it and I don't remember what size, probably AA maybe two or three. I didn't pay much attention as it was a functioning toy upon receipt. Check in the info following the screen on toy and it should say. Have a good one!!!
