RC batteries
The kid in the house has lots of RC toys or remote controlled toys. These toys have different types of rc batteries. And in order for him to enjoy all of his RC toys, his father tried his best to buy and store different types of RC batteries for the kid’s convenience. Since he is already a big boy, he can just replace any of the RC batteries in any of his RC toys that he wants to play with. Though, there are times that he wants attention and he will ask me to replace the RC batteries for him.
