Water Powered Calculator

£18.50

The Accountants Calculator runs on the H2O replaceable battery. The calculator has a 12 digit display screen, which makes it suitable for basic day to day use at home or at work. 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 it's life extended indefinitely.
