Danelectro2D9V 9V Batteries (2 Pack)

where are they made?

Title say (4 pack). Am i gonna get 2 battery or 4? Seem like other customers got trick by the title.

Are these alkaline? There is no indication on the product itself.

How thick are the batteries because normal 9-volt batteries from Energizer are too wide to fit in my old Spica transistor radio?
