Traction batteries are mainly used in heavy industrial electrical applications such as: electric forklift trucks, electric tractors, large industrial cleaning machines, aerial platforms, …A traction battery consists of several cells of 2V. When those cells are connected in series, you get higher voltages. A traction battery of 24 volts has 12 cells, a 48 volts battery has 24 cells, a 80 volts battery has 40 cells. To recharge a battery, the cell voltage has to be increased to above 2 volts by an external voltage source.Traction batteries differ from starter batteries because they have been developed to provide a certain amount of energy for longer periods. As a result, traction batteries usually have a much higher capacity than starter batteries.
