(SANYO), a world leader in rechargeable battery technology, is pleased to announce the new additions to line-up of the eneloop rechargeable battery series, the “eneloop pro”, the “eneloop plus” and their charger sets to be released for the Japanese market.

The new “eneloop pro” battery has a 25% higher capacity than regular eneloop batteries, making it especially suitable for gadgets with high power consumption, such as digital cameras, strobe lights and flashlights etc. The new “eneloop plus” battery, with its overheat prevention function which suppresses overheating in case of improper use, is ideal for toys.



In addition, SANYO will also launch the “Wireless Charging Carrying Case” which can wirelessly recharge eneloop batteries. The carrying case is compliant with ‘Qi’, a standard of the Wireless Power Consortium (WPC) who are working towards the international standardization of wireless recharging technologies.

The “eneloop pro” will be available from July 21, 2011 and the “eneloop pro” charger set will go on sale from September 21 in Japan only. The “eneloop plus” and its charger set will be available from December 1, 2011, also in Japan only.

The new addition to the line-up, the “eneloop pro” rechargeable battery with Min. 2400mAh, has a 25% higher capacity than the regular eneloop battery with Min. 1900mAh. This means that the battery has a longer life than the eneloop and is more suitable for professional use of digital cameras, strobe lights and flashlights etc.

In addition, thanks to the eneloop’s self discharge control technology, a fully-charged “eneloop pro” is capable of holding approx. 75% of its initial capacity and is ready-to-use even after 1 year of storage. The “eneloop pro” can be recharged by existing eneloop chargers as well. (An equivalent model of the “eneloop pro” has been marketed in Europe as “XX (double X)”.)

In accordance with the “Green Power Certification System,” the “eneloop pro” batteries are charged by “Green Power” from photovoltaic generation. A part of the electric power used for manufacturing “eneloop pro” batteries (the amount equivalent to that used for factory pre-charging) is generated using clean, renewable solar energy, part of SANYO’s initiative to realize a “Clean Energy Loop,” where power is generated from renewable energy sources, stored for use when needed in batteries, and conserved or used efficiently.
