The F-718SGA features a practical dual power source. Solar power ensures maximum energy saving, whilst back-up battery power means this calculator never lets you down whatever the light conditions. The ‘auto power-off’ function switches the calculator off after 7 minutes when not touched or not in use, saving even more energy. Also this calculator has a replaceable battery for a long life, unlike some calculators that have to be disposed of after single battery use.
