In many electrical devices the old issues (for example, ampervoltmetry Ts20, Ц4315, etc.) as an internal power source used battery KBS (L,X), sedss,7-4,1 In, unfortunately, which are currently very difficult as the industry is almost not released. This situation makes the owners of such devices to switch to other batteries, even of different denomination — to have the necessary EMF through a variety of their compounds, as they say, a trick.
Not privy to his secret for a long time to turn this wooden “hedgehog” in my hands, trying to figure out how he knows and not full at all if he is so closely connected with each other all the cubes, as if glued.
