Sanyo's ever-so-practical Eneloop rechargeable batteries, you'll be smitten with its two latest AA additions. First into the battery compartment is the 2400mAh Eneloop Pro; it's loaded with twenty-five percent more juice than the standard model, and is a perfect match for your power-draining Nikon Speedlight -- not quite as formidable as the 2,500mAh XX series, though. Moving onto the next slot is the Eneloop Plus, which adds a positive temperature coefficient thermistor -- a resistor that prevents the batts from reaching skin-scorching heat levels in kids' toys. Blazing Hello Kitty anyone? Both will come in packs of two or four, and also as bundles with a charger. Residents of Japan will be able to pick up the batteries at varying points this year, but aside from the ¥1,260 (about $15) Pro two-pack, pricing remains open.
