Crowe...you might look at Sanyo Eneloop NiMH rechargables for your AAs...I am trying to standardize to AAs and Ds (Ds for my ventilation fans, LED lantern, and MagLights, AAs for the mini MagLite LED and Grundig radio ), with the purchase of a quality AA LED headlight I am down to a couple of inexpensive AAA LED headlights and Fenix E01 EDC with AAAs, a couple of special purpose weapon lights using 123s (Surefire 6P and Scout Light)

I'm relying on a gallon of 1-K kerosene and two Dietz lantern for most of my illumination
