Extends battery life

With time, the springs holding the batteries in your devices can get loose which can render the device useless. A small piece of foil will do the trick. Just fold the aluminum foil into a small pad and wedge it between the spring and batteries and it’s done.

Another one for batteries is how to add life to your battery. If your batteries run down and you don’t have news one just yet, you can also use some aluminum foil. All you need to do is to place the foil on the positive tips of the batteries and your batteries will last for a little while longer.
