Lately Jason and Matthew like to play with remote controlled cars in our backyard.
Matthew still doesn't understand when the batteries are empty, that's why I have to make sure that there are always batteries available at home. It costs me a lot of money when i need to buy new AA batteries for the children's toys every time. So... I am thinking to buy a rechargeable sanyo eneloop battery. I am sure that over a longer period, it will save us lots of money if we use this rechargeable battery.
