Insofar as LED flashlights are concerned, my definition of 'weird batteries' is any power cell that isn't one of the following: AAA, AA, C, or D. The rest are not cost effective and often not readily available. If a flashlight is powered by batteries in one of these four configurations, it passes the 'battery test'.
Meeting the 'battery test' ought to be viewed as an essential basic requirement for the common sense flashlight buyer. A 'cool light', with some great features, but failing the battery test, should be viewed as a DUD. Button cells may be occasionally OK for a throw away, and/or little used, miniature pocket light. They are; however, not for serious use.
Flashlight designers who build their flashlight configurations around around flaky, strange, and/or expensive batteries are either missing some critically important brain cells or they think the consumer suffers from such an affliction. With readily availabe LED driver circuits, the need for weird cells with high (such as 3V) terminal voltages is not justified.
Many enthusiasts are well aware of the importance of the 'battery test' and, yet, apparently many others are not. The rule, simply stated, should be, "Don't buy LED flashlights, unless they pass <font color="red"> the battery test! </font>
