Many vintage radios and other collectible electronic items use large, expensive 9-volt batteries that are either no longer made, or very expensive. The old batteries often have contacts which are larger than the ones used today.
These adapters let you use inexpensive AA or 9-volt batteries instead. They mate with the contacts in your vintage device, making it unnecessary to modify and potentially devalue collectibles.
