Since its launch in November 2005 eneloop has become well-known around the world as it has revolutionized the consumer-use rechargeable battery segment with its unique features: * rechargeable approximately 1,500 times * coming pre-charged, making it usable immediately after purchase * its unique design departing from the look of traditional batteries What is the difference between the "old" and the "new" improved eneloop? An extra of 500 charging cycles - instead of being rechargeable 1000 times, the new eneloop is even rechargeable up to 1500 times. Improved self-discharge. 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.
