Checking the battery
The level of the electrolyte Battery is filled with sulfuric acid, diluted with distilled water. Since water can evaporate from time to time should check the electrolyte level and if necessary top up with distilled water. The electrolyte should be between labels on the housing of the battery. Batteries are usually protected from transfusions. To refill unscrewing the plug on the cover of each battery and fill with distilled water until it will not be visible. Batteries may also have a tray, covered with a lid. The charge level (

To determine the state of charge of the battery electrolyte density hydrometer is used. To control unscrewing the cap and lower the hydrometer into the tube bankiris. 317). Use a rubber blower to recruit a sufficient amount of electrolyte that it could float to float freely. Depending on the state of charge changes the density of the electrolyte. If the density is 1.28 g / cm3, the battery is fully charged; at 1.12 g / cm3, the battery is fully discharged. Intermediate values indicate the charge status. Check the state of charge all batteries. Charging the battery In the fully discharged battery should be topped up with distilled water only after the charging. During charging, the electrolyte level rises, so filled, in accordance with the instructions battery can "boil". First charging current should not exceed 10% of the battery capacity, such as battery capacity of 45 Ah it should be 4.5 A. Once it reached a voltage equal to approximately 2,4-2,45 In each cell, the current charge should be reduced by half. Depending on the design of the charging current of the charger in most cases will be reduced automatically. The battery is considered fully charged if the density of the electrolyte in the next two hours is not changed. Corks batteries usually have to turn away and remain on the loose holes. Thus provides the opportunity to enter detonating gas composed of hydrogen and oxygen. Since the intensive charging inevitably occurs splashing electrolyte, the surface adjacent to the battery, should be protected. When charging indoors is necessary to ensure good ventilation. In no case do not use an open flame to illuminate the holes in the battery. When applying battery charger can be left in the car. For safety reasons, disconnect the two wires from the battery terminals.
A warning When disconnecting the battery information is erased from the memory of the electronic memory devices. |
Refitting

The battery is located in the engine compartment and fixed pressure plate 2 (Fig. 318) and the clamping plate 1. Before removal, disconnect the wire from the battery. Always disconnect the negative cable. Then unscrew the bolt 3 and remove the pressure plate 2 and remove the battery. When installing the battery, you must first clean the terminals, make the battery to force a flange on one side for clamping plates 1. Set the pressure plate 2 and firmly press it to the battery, insert the bolt and tighten to 20 Nm. To install on vehicle batteries are suitable height 175 mm or 190 mm. Start the engine with the discharged battery The easiest way to start is to start using a special wire to connect to the battery of another vehicle. The wire should have a large sectional area and a large coupling clips to pass a current from one battery to another. You must first connect the "plus" wire, then "minus". The assistant should start up the engine and maintain a high speed, the generator can generate additional current. The best-known way to start the engine with very low battery - towing vehicle.
