Been doing it since I was a kid. Nowadays it's laptop batteries. The vast majority of them are filled with 18650 lithium cells. These put out roughly the same voltage as two c cells, but have way more capacity. There is one caveat, though: battery management. Many 18650 batteries have internal battery management, many don't.
