How big is a traction batterys capacity?
A traction battery’s capacity will decrease toward the end of its life. Unless a specific problem occurs, this will be a gradual decrease and ample warning of reduced capacity will be evidenced by the slowing down of the vehicle toward the end of the day’s work. A traction battery is considered to be at the end of its useful life when its capacity decreases below 80% of its rating. However, it can sometimes be transferred to a smaller job to provide additional life and service. As a motive power battery usually discharges every day in the course of its regular performance, it is seldom necessary to conduct a formal test of its capacity. Most users do not have the facilities to do this conveniently or accurately. If any such testing is desired, consult the Dart Traction service engineer.
