The control of level of electrolit

The liquid in the storage battery consists of the sulfuric acid dissolved дистилированной with water. Any part of this water can evaporate or break up in the course of gymnastics to hydrogen and oxygen.

In cars Audi 80 it is established so the storage battery not demanding servicing corresponding to standard DIL 72311 and having rather large supply of water. In normal conditions it should to do without all service life доливания some the new distilled water. The raised expense of water is caused only by the raised temperature of air, long stay in hot regions (holiday), a faulty regulator of pressure of the generator, the self-category at long parking of the car or the deep category caused, for example, included all night long lay headlights.

 PERFORMANCE ORDER

  1. The electrolit in the storage battery should reach at least the bottom mark in the case, put by a varnish or squeezed out, but, at least, it is good to close upper edges of plates.
  2. At the lowered level of a liquid to unscrew a stopper.
  3. If the storage battery is charged normally it is necessary to add the distilled water to the top mark or 15 mm over upper edges of plates.
  4. If the storage battery is strongly discharged to add only so much water that plates have been covered from above because at repeated gymnastics liquid level considerably will raise.
  5. To add to the top mark only after gymnastics.
  6. The quantity of water from a bulk small bottle should be well dosed out because it is easy to overflow the accumulator.
  7. The overflowed storage battery "begins to boil", acid acts at a stopper.

Removal of the storage battery

Removal of the storage battery at models with 4 and 5-cylinder engines. To uncover the storage battery (4), to disconnect a hose for tap of gases (marksman). The first to disconnect the negative plug (2), then to disconnect положителльную the plug (1). Now it is possible to weaken a bolt (3) on a fixing plate in the bottom part of the accumulator.


Removal аккумулярной batteries of the 6-cylinder engine occurs the same as and at other versions:

1 – a positive conclusion;
2 – a negative conclusion;
3 – a bolt of a fixing plate. The hose of tap of gases on an illustration is covered by wing edge.


 PERFORMANCE ORDER

  1. To disconnect anticreeping system and a radio code that they could be included again after accumulator connection.
  2. Models with 4 and 5-cylinder engines: to uncover the storage battery after easing of both fixing clips on the right and at the left, or high-speed locks.
  3. Models with 6-cylinder engines: for removal of protection of the storage battery to unhook plastic fasteners below, one in a direction to the engine and one in a direction to a wing.
  4. The first necessarily should disconnect a negative wire for short circuit prevention at the further work with the accumulator.
  5. To weaken a nut on the plug of a negative wire, to disconnect the plug from a negative conclusion.
  6. To weaken and remove the plug of a positive wire.
  7. To turn out bolts of a fixing lath in the bottom of the storage battery, to remove bolts and a lath.
  8. To disconnect a plastic hose from central газоотвода.
  9. To take out the storage battery.
  10. At installation at first to connect positive, then negative wires.
  11. Without application of force to mix plugs of wires it is almost impossible, because a positive conclusion thicker than a conclusion negative.
  12. Again to include the alarm system and radio.

Care of contacts of the storage battery

 PERFORMANCE ORDER

  1. Crystals on accumulator plugs to wash warm water with soda or to process «Leutralol» from Varta.
  2. To grease conclusions and wire plugs кислотозащитной with plastic greasing («Ft 40v1» from Bosch).
  3. It is impossible to put greasing on lateral faces of conclusions and an inside of plugs, problems with contacts differently are possible.
