dry cells
Flashlight power sources
Dry cells are batteries that use a paste electrolyte rather than liquid, making them portable and leak-resistant.
The common cylindrical batteries—AA, AAA, C, D—are dry cells.
The term distinguishes them from wet cells like car batteries, which contain liquid acid.
The flashlight takes two dry cells.
