Water Powered Compact 8 Digit Calculator 
Water Powered Compact 8 Digit Calculator

The H2O calculator  is designed and manufactured for both professional and home use in mind. By just adding water you are providing your product with an endless source of energy. At the end of the H2O battery’s life (indicated by dimming of the display) simply replace the battery and start all over again. (Replacement water powered batteries are readily available from us). Unlike conventional solar powered calculators the H2O Compact Calculator can be used in all light conditions - meaning no more fading displays at that critical moment.

The H2O batteries are easy to refill and can provide constant power for up to 3 months with just a few drops of water.

Not only is the H2O Compact Calculator environmentally friendly, innovative and ergonomically designed, it has a large 8 digit display and keyboard and offers all the functions demanded by professional users. It is the latest in ecological and environmental design, incorporating the revolutionary and patented, H2O powered battery, together with conventional digital technology.

The 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.
