H20 Eight Digit Calculator with Replacable Cell

This calculator runs on fully recyclable, water based batteries, which have an estimated life of two years. The H2O batteries are easy to refill and can provide constant power for up to 3 months at a time from just a few drops of water.

The batteries contains two electrodes of specially formulated alloys, one positive, and the other negative. When immersed in water, an electrochemical reaction takes place resulting in the production of electrical energy. Just refill with water every few months to replenish that which has evaporated.

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.

All the components of the H2O battery are fully recyclable, so the benefits over traditional batteries are countless. Replacement water powered batteries are readily available from Leaf Living.
