Yes, most battery operated toys for my kid use these small AAA batteries and rechargeable concern is that they also discharge when not in use so that they not. So we put the batteries and when he wants to play again three months later, the thing does not wake up. So although I prefer rechargeable batteries, well it is not suitable for all uses.
So this package allows for a relatively economical price to have a reserve of 32 tidy piles. Even when the boxes are opened, one can always keep itself in sending cardboard box you see in the picture.
