Very useful alternative
Bought these so I could use them in my 3 & 4 cell Maglights. Since I use the Sanyo Enloop 2000 MAH batteries for my cameras these were the perfect item so I would't have to purchase any more D size cells. These adapters work perfectly, however in the case of the Maglights, the spring in the tailcap will not make contact with the bottom of the AA battery. My solution, was a small metal disc made from aluminum. These adapters are very light weight, so this does reduce the mass of your Maglight... it's not near as heavy, if you were to use it for protection.
