13.5. Rules of care of the accumulator

THE GENERAL DATA

If you are going to keep working capacity of the battery throughout as much as possible long period of time, observe following rules:

  – At the idle engine switch off all electric devices in the car;
  – Switching-off of the battery from a car network begin with a negative wire;
  – Each 15–20 days (through 2 500 km of run) wipe the accumulator from a dirt in order to avoid its self-category. With the same purpose it is necessary to eliminate begin to flow electrolits and to isolate from the case a fixing framework;
  – The accumulator should be reliably fixed on the car. Watch that plugs of wires have been strongly fixed on accumulator conclusions, explosion otherwise is possible;
The accumulator can continuously work in стартерном a mode no more than 15 seconds; the break between cycles should ` make not less than 60 seconds;
  – ериодически check the voltmeter the pressure developed by the relay-regulator. Indications are necessary for removing directly on plugs аккумулято ра at the working, heated-up engine. The pressure size should keep within a range from 13,8 to 14,5 Volt;
  – On served accumulators it is desirable to check up level and electrolit density through each 3 000 km. Electrolit level is checked on a special mark in transparent cases or by means of a special glass tube in opaque cases. The electrolit should close an upper edge of plates on 10–15 mm. The electrolit density is checked with the help ареометра. If the density became below value of 1,23 g/sm³ in the winter and 1,19 g/sm3 in the summer, additional charge is necessary;
  – Even if the generator and a regulator of pressure are serviceable, and electrolit level in norm, additional charge with the help зарядного devices is necessary once a month in the winter and each 6 months in other seasons;
  – It is possible to store the accumulator filled in with electrolit only completely charged, thus the electrolit density should be checked once a month;
  – Accumulator gymnastics make a current making exactly 0,1 from nominal capacity. For example, the accumulator in capacity 50 А/ч is necessary for charging a current force 5 And, at the unscrewed stoppers of jellied apertures;
  – It is not necessary to fill in in the accumulator of electrolits with relative density more than 1,28/sm3 Trying to increase, thus, a starting current, you in a short time interval will put out of action the accumulator. For the same reason to lead up level of electrolit to norm it is possible only the distilled water;
  – In the opaque served battery electrolit level can be measured by means of a hollow glass tubule, having closed its one end a finger. In taken "test" the height of a column of a liquid in a tube will correspond to height of excess of level of electrolit over an upper edge of plates;
  – It is necessary to remove begin to flow electrolits or to neutralise possibility of influence of electrolit on surrounding subjects; to make it it is possible by means of a 10 percent solution of sal ammoniac or soda.

Operation of the discharged battery, especially is not supposed in the winter.

In the discharged accumulator the water percent in electrolit is too high. The electrolit can freeze and put out of action the accumulator case. Do not try to charge the frozen accumulator the big current or to get the car from an extraneous source, Allow to the accumulator to thaw, and then try to restore it by gymnastics a current of small force, and it still can serve.

Crack in bank of the served accumulator – not always the reason of its replacement. Pour out electrolit, dry up and wash out gasoline a crack then process its file. Sawdust, having formed шиеся at crack cutting, mix with эпоксидным glue or шпатлевкой. With the received structure carefully cover a crack. After the given procedure of electrolits fill in not earlier than in 24 hours.
