The vehicles are equipped with a lead starter battery 6-ST55A or its imported analogues. The battery case is made of translucent plastic with marks for the maximum and minimum electrolyte level allowed in operation. The battery is low-maintenance, i.e. equipped with a device for collecting evaporating water, however, during prolonged use, especially in hot climates, the electrolyte level may decrease. If there were no cases of electrolyte splashing, only distilled water should be added. Strictly observe the safety regulations when working with the battery (see Repair Safety).
