Since I have heard for the first time 2 years ago by the Eneloop batteries and tested it, I'm a fan of risiger. I know of no batteries that hold a charge longer than the Eneloop. After 1 month without use many other batteries often have to half of the charge already lost 1/3. Older batteries are after a month sometimes almost dead. Not as the Eneloop which still have after one month 80% -90% of the power. What use 2800 mAh power cheaper battery when it is no longer available after a short time? Since the batteries Eneloop lower power rating is much better, because in the end one so, how long you can use much power, and not how much power would theoretically maximum possible. And this gets Eneloop me 10 out of 5 stars! As long as I'm not adverse experiences, I buy for now only Eneloop batteries.
