2. Check electrolyte level in the battery (concerns only equipped with removable covers the batteries needing service) – electrolyte has to hide completely lamels, otherwise in banks the corresponding amount of the distilled water follows. DO NOT POUR, – excess of electrolyte at excessive battery charging will begin to overflow mouths! By means of the areometer (ask in shops of automobile accessories) measure the specific weight of electrolyte (see an accompanying illustration). Uncover jellied mouths and take away the areometer electrolyte test serially from each of battery cans. Following instructions of manufacturers, determine the specific weight of electrolyte by the provision of a measuring float of the device. At the normal level of a charge the specific weight of electrolyte has to make 1.270 units (a green zone of a measuring scale). At excessively low density of electrolyte (a red zone of a scale) the battery should be charged (see the Head Routine maintenance). The output tension of the battery has to make 12.6 B or is slightly higher.
