"0.59 inches in diameter"? That's driving me mad at all of the modern AAA flashlights manufacturers. The AAA cell is only 0.41". Add 0.07" (1+1 mm) for the more than supper-heavy-duty walls and you should never go over 0.5" - the Maglite Solitaire's diameter. Why everybody desperately adding so much "fat" to AAA in a simple flashlight?

(actually, I probably know the answer. Because in China they still have severe manufacturing quality problems and cannot drill the battery hole exactly centered to the body, so they are trying to reduce defective walls production increasing their thickness severely).
