SANYO eneloop XX 8 Batteries type AA - LR6 - with 2 x 2400 mAh "Mertrado" Transport Case 4 AA battery (Mignon / LR6) or AAA (Micro / LR03) (Electronics)
Although Sanyo announces a lifetime below average (! 500 cycles, making it still long enough), these batteries work exceptionally well: good holding of the load without use, long-term landfill. Have become my portable electrical equipment reference.
