: The rechargeable batteries of the future have arrived

Sanyo has announced their ENELOOP batteries yesterday. These rechargeable AA and AAA Nickel Metal Hybrid batteries have as main characteristics:

1) they are ready to use as they are already charged. Sanyo seems to have solved the "Self-Discharge" problem (a rechargeable battery discharges slowly when it's not being used).

2) the batteries are "eco-friendly" and can be recycled.

3) the battery life is greater than a Dry Cell type of battery. Sanyo did some tests and they say that you can take 4.4 times more pictures with their batteries than with a normal Dry Cell battery. They can be recharged more than 1000 times too before they start losing their initial capacity.
