  • Water Powered
  • 8 Digit Display
  • Compact & Light Weight
  • Ergonomically Designed
  • For Professional or Home Use The new H2O Compact Calculator is the latest in ecological and environmental design. Incorporating the revolutionary and patented, H2O powered battery, together with conventional digital technology the H2O Compact Calculator offers the user an environmental design solution for a product that is used in every day home or office life.

    This has all been made possible by groundbreaking developments in portable power technology operated by an inexhaustible resource - “water”. The patented technology utilises two electrodes consisting of specially formulated alloys, one positive, and the other negative. When immersed in an electrochemical reaction takes place resulting in the production of electrical energy.

    To maintain a constant supply of energy simply refill as the evaporates, typically every 2 to 3 months. The H2O battery has a minimum continuous life of at least 2 years. In addition to this, the H2O 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 and 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, and the recycling of such waste is not only expensive but often incomplete, resulting in hazardous pollution and damage to our environment.
