This Eneloop Power Pack Kit from Panasonic includes a 4-position charger, 8 AA and 2 AAA rechargeable batteries, as well as two C and D spacers, and a carrying case.
The Eneloop batteries come pre-charged and ready to use out of the pack. They are not subject to any memory effect so you can charge them up to 2100 times whether they are fully or partially drained. After ten years of non-use, they maintain 70% of their charge. These cells have also been improved for enhanced performance in temperatures down to -4°F.
The included battery spacers allow you to power devices that normally take C or D batteries, with AA batteries. A carrying case is included to keep all of the contents together.
