BRUSSELS--()--Panasonic Energy Europe NV will sell eneloop rechargeable batteries under the Panasonic brand from April 2014. The new product lineup will feature three different types – an eneloop standard model, "eneloop pro" high-end model, and "eneloop lite" entry model. The new eneloop standard model can be recharged up to 2,100 times*2, making it one of the most reusable batteries in the industry*3.

eneloop is built on the concept of "For a Sustainable Lifestyle." It combines the reusable qualities of a rechargeable battery with dry battery qualities which is immediate usability after purchase or long-term storage. All batteries will naturally self-discharge but eneloop offers significantly improved resistance to this self-discharge. A charged eneloop can be left for up to an industry leading*4 five years – and still be used afterwards without the need for a further charge.

eneloop was first launched in Japan in November 2005. Today, the batteries are on sale in over 60 different countries worldwide, with cumulative unit shipments having passed the 300 million mark (as of March 2014).

The concept and design of the eneloop batteries have been highly praised and earned a number of different awards – including a "Good Design Award – Gold Award" in Japan (2006), an "iF Design Award – Gold Award" in Germany (2008), an "IDEA Award" in the United States (2008), an "Australian International Design Award" (2009), and a "Design for Asia Award" (2010). Panasonic user satisfaction surveys have shown that more than 95% of users*5 are satisfied with the products in the United States, Germany, Thailand, and China.
