Perfect *just use a piece of aluminum foil if needed*
These are great and turns my D size flashlight into AA rechargeable battery use perfectly.<br />Not really perfectly because my Mag-Lite flash lights have a large spring on the end and would miss making contact with the battery. To fix this just fold a small piece of foil (a few layers keeps it strong) over the spring to close the hole and it's ready to go. The foil and spring self adjust to make the right contact. These adapters saved the nights thru Hurricane Sandy here in NJ. A great product that makes expensive D batteries a thing of the past.
