principle of water power battery:

The product used in everyday life offers the user an environmental design solution. It is a groundbreaking development that portable power technology operated by an inexhaustible resource - "water". The  technology utilizes two electrodes consisting of specially formulated alloys, positive and negative. When they are immersed in water an electrochemical reaction takes place resulting in the production of electrical energy. To maintain a constant supply of energy simply refill as the water evaporates every 2 to 3 months. The water battery

has a minimum continuous life of at least 2 years. In addition to this, the water battery (unlike all other conventional batteries) can be stored in its dry state indefinitely and can be left to dry out at any time during its life.
