Since its launch in November 2005, eneloop (by SANYO) has become well-known around the world as it has revolutionized the consumer-use rechargeable battery segment with its unique features as stated below:
Rechargeable approximately 1,000 times -Coming pre-charged, making it usable immediately after purchase - Its unique design departing from the look of traditional batteries - An extra of 500 charging cycles - instead of being rechargeable 1000 times, the new eneloop is even rechargeable up to 1500 times - Improved self-dischcharge. Even though the self discharge of the old eneloop was already very impressive, you can store the new eneloop for 3 years and still it will retain 75% of its capacity - You need a battery, which is reliable even when having cold temperatures? Before eneloop was suitable for temperatures as low as -10°C – now even until -20°C - The new eneloop is even more environment-friendly as it is pre-charged with solar energy in Japan.
Specs
The specifications of eneloop will remain as they are. Both types are having a nominal voltage of 1,2 V. The Mignon-eneloop (AA) has a rating capacity of 2000 mAh, the Micro-eneloop (AAA) does have a rating capacity of 800 mAh.
Old Or New?
All original SANYO battery packages containing the improved eneloop have the information “Up to 1500 times” on the front. Also you can differentiate the two generations by checking the model name which is written on each eneloop. The “old” cells have written HR-3UTG (AA) and HR-4UTG (AAA) on them, the improved eneloop instead HR-3UTGA (AA) and HR-4UTGA (AAA). Additionally the new models have a crown on them.
Solar Pre-Charge
The new eneloop batteries are pre-charged in Japan by “green power” from photovoltaic generation. This means that a part of the electric power used for manufacturing (the amount equivalent used for factory pre-charging) is generated using clean, renewable solar energy.
