The batteries, a set of piles built by alternately materials, which can produce a potential difference are one of the many components which we use everyday and of which we ignore almost everything and we underestimate the importance.
Plenty of equipment, useful or completely unnecessary, stay in our life working with batteries. We do not want to make a list, but we suggest you to begin in the morning it when the alarm rings, which has no more the tick of mechanics, but the absolute silence of the battery.
Then continue, but do not forget the remote control cars, the car itself etc..
The batteries are everywhere and unfortunately we throw them everywhere, if we are not able to store them in appropriate containers, always too few and always hidden, we find always when not needed. A good rule is to take them in the shop where we buy the new ones.
