The storage battery, directly or indirectly, plays a vital role in the life of everyone today. In the industrial world it moves Materials, starts the engines of railway locomotives, control power systems, and performs and performs an infinite variety of special functions. In our personal contacts it starts our cars, provides light and comfort in railway coaches, and propels our golf carts. Whether seen or unseen, whether in a airplane or a mine it is a part of our way of life.
A battery cannot, however, function alone. Its original energy, and the replacement of that which it delivers, must came from a charging source of charger. In fact, the proper design and functioning of the charger are by far the most important factors in the satisfactory operation and service life of the battery.
