Sanyo has presented new batteries within its Eneloop range, which have very interesting features on the paper. According to the manufacturer, these AA and AAA batteries may be recharged more than 1,500 times (500 more than the rest of the market), keeping the power inside even three years after his last load, keeping 75% of it available yet. They have not commented on pricing or availability, but even though they are more expensive than usual, I think that in the long run they will make us a favor to our planet, compared with disposable ones both our pocket.
