3.11. Check of a condition of the battery and care of it

Address also materials of the Head Sistema of electric equipment of the engine. The rechargeable battery is placed at the left in a forward part of a motive compartment.


During the work with the battery it is necessary to undertake certain security measures. At banks of the battery there is always extremely a flammable hydrogen therefore do not allow an arrangement about the battery of naked flame. Electrolyte of the battery represents solution of sulfuric acid which at hit in eyes or on open parts of the body causes serious injuries. Besides, acid corrodes clothes and paints. At shutdown of the battery always the first disconnect a weight cable, and connect it in the last turn!

Care of the battery is very important procedure which implementation requires the corresponding tool.

 PERFORMANCE ORDER

  1. Before the procedure of service always at first switch off the engine and switch-off all electric devices, then disconnect a weight cable from the battery.
  2. The considered cars are completed with completely sealed batteries which are not demanding special leaving. Only check of level of electrolyte is supposed, and adjustment of its level is not provided.
  3. Check electrolyte level in each of battery cans – it has to be between the marks MIN and MAX in the battery case. Some batteries are supplied with the color indicator which is clarified at the low level of electrolyte. If necessary the unattended accumulator is subject to replacement.
  4. If the served battery is used, add only the distilled water and then close covers of cans.

Overflow of cans can lead to transfusion of electrolyte during the accelerated charging that will cause corrosion and damage of the components, next to the battery.

  1. If the positive plug and a collar of a wire of the battery are equipped with a rubber protector, make sure that it is not torn and is not damaged. It has to close the plug completely.
  2. It is necessary to examine periodically an external condition of the battery on existence of such damages as cracks in the case.
  3. Check reliability of tightening of collars of wires of the battery providing good electric connection. Check each of wires on all length for existence of cracks and attritions of isolation and the carrying-out core.
  4. At detection of traces of the corrosion (which is usually representing a friable raid of white color) disconnect wires from plugs, smooth out them a wire brush and again connect. Emergence of corrosion can be minimized by installation of specially processed washers, or by drawing on plugs and collars of wires of a layer of acid-free vaseline or suitable lubricant after their connection.
  5. Make sure that the pallet of the battery is in satisfactory condition, and the bolt of a fixing collar is reliably tightened. If the battery was removed from the pallet, track that in installation time on it any foreign objects did not lie. At a latching of a fixing collar do not tighten its bolt too hardly.
  6. Corrosion traces from the pallet, cases of the battery and surrounding surfaces it is possible to remove by means of water solution of baking soda. Apply mix with a small brush, let's it stand and then wash away plentiful amount of clear water.
  7. The metal surfaces of the car which underwent corrosion should be covered with primer on a zinc basis and then to paint.

Additional information on the battery and on start of the engine from the auxiliary power supply can be found in the Head Sistemy of electric equipment of the engine and in Introduction.
