According to Sean West, an American, this time is enough to charge his newly invented battery, which is based on lithium-ion capacitors. And it is not only the charging speed that makes the battery stand out but also its safety and diversity of possible applications. The battery, while being the same size as a regular AA battery, lasts just as long as any conventional battery of the same type.
However to be able to use the battery users also need a special charging device as no regular ones are suitable for the purpose. Anyways, the set of a battery and a charging device is expected to cost not more than 25 USD.
The inventor intends to present his first products this October already, the range including both standard AA batteries, AAA batteries and batteries of other typical sizes.
