{ } To keep the battery going, refill it as the water evaporates typically every 2 to 3 months (the battery will last a minimum of 2 years continuous use). The patented technology utilises two electrodes consisting of specially formulated alloys, one positive, & the other negative. When immersed in water an electrochemical reaction takes place resulting in the production of electrical energy. In addition to this, the H2O battery (unlike all other conventional batteries) can be stored in its dry state indefinitely & can be left to dry out at any time during its life & its life extended indefinitely. As all the components of the H2O battery are recyclable, the benefits over traditional batteries are countless. Every year billions of conventional dry cell batteries are used, & the recycling of such waste is not only expensive but often incomplete, resulting in hazardous pollution & damage to our environment. The H2O Multifunction Clock is the most unique powered product anywhere in the world today. By just adding water you are providing your product with an endless source of energy. At the end of the H2O battery
