The lcd displays battery voltage when the button is pressed or when initially plugged in display voltage range is 3 to 16v resolution is 0 1 volt. Display voltage range is 3 to 16 volts. The colder the temperature the higher the lcd voltage what happens if the lcd driving voltage is too low if the supplied lcd voltage drops too low the display is under driven and will produce segments that are grey.

Sensitive lcd digital display the small battery voltage reader with a pvc waterproof screen poterctor clear and bright green backlight lcd display from any angle. Displays the voltage in numbers with one digit to the right of the decimal point ie. Actually it s not rocket science but i had waited for it 2 3 weeks and didn t want to blow it at first try. Digital voltage indicator with lcd display deltran battery tender s digital voltage indicator with lcd display shows voltage range from 3 to 16v resolution is 0 1 volt.
