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 -10C - now even until -20C. The new eneloop is even more environment-
friendly as it is pre-charged with solar energy in Japan
