Power Knowledge of Cells

My father never trashes any old batteries because he knows that combined with another used one, a few weeks later, it can juice up the wall clock any such device. I know its not recommended, but bottom line is that people DO it! So if you can’t break them, may as well join them; provide them with a Digital Measuring Paper. It features soft OLED screen and paper-thin IC that displays the amount of backup juice in a cell. At least two like-powered batteries can be used together more effectively.

    Very nice but I’d lose that in an instant

  • miguel says:

    This idea is very old.

    The first time I used something like this with my own hands was in the late ’80.

  • Max Xie says:

    It’s not a brand new idea.Before disign the product ,the designer should google some keywords about their idea first, such as “Duracell POWERCHECK ” first…

    The form is very nice and cool.However, in my personal opinion, if the device has a function of collecting the remaining power of the cells,that will be better!!

  • Superb blog! Do you have any tips and hints for aspiring writers?
    I’m hoping to start my own blog soon but I’m a little lost
    on everything. Would you advise starting with a free
    platform like WordPress or go for a paid option? There
    are so many options out there that I’m totally confused ..
    Any suggestions? Thanks a lot!
