Control of level of electrolyte
Liquid in the battery consists of sulfuric acid, the divorced distilled water. Some part of this water can evaporate or break up in the course of charging to hydrogen and oxygen.
The battery which is so not demanding servicing conforming to the DIL 72311 standard and having rather large supply of water is installed in Audi 80 cars. In normal conditions it has to do all service life without dolivaniye of the new distilled water. The raised consumption of water is caused only by the increased air temperature, long stay in hot regions (holiday), the faulty regulator of tension of the generator, a self-discharge at long parking of the car or the deep category caused, for example, by the headlights included all night long parking.

- Electrolyte in the battery has to reach at least the lower mark in the case put with a varnish or which is squeezed out, but, at least, it is good to close the upper edges of plates.
- At the lowered level of liquid to unscrew a stopper.
- If the battery is charged normally, it is necessary to add the distilled water to the top mark or 15 mm over the upper edges of plates.
- If the battery is strongly discharged, to add only so much water that plates were covered from above because at repeated charging liquid level considerably will increase.
- To add to the top mark only after charging.
- The amount of water from a bulk small bottle has to be well dosed because it is easy to overflow the accumulator.
- The crowded battery "begins to boil", acid acts at a stopper.

Removal of the battery
|
|
Removal of the battery at models with 4-and 5-cylinder engines. To uncover the battery (4), to disconnect a hose for removal of gases (shooter). The first to disconnect the negative plug (2), then to disconnect the positive plug (1). Now it is possible to weaken a bolt (3) on a fixing plate in the lower part of the accumulator. |
|
|
Removal of the akkumulyarny battery of the 6-cylinder engine happens as well as at other versions:
1 – positive conclusion;
2 – negative conclusion;
3 – bolt of a fixing plate. The hose of removal of gases on an illustration is covered with edge of a wing. |
|
|
- To disconnect anticreeping system and a code of radio that they could be included again after connection of the accumulator.
- Models with 4-and 5-cylinder engines: to uncover the battery after weakening of both fixing clips on the right and at the left, or high-speed locks.
- Models with 6-cylinder engines: for removal of protection of the battery to unhook plastic fasteners below, one towards the engine and one towards a wing.
- The first surely should disconnect a negative wire for prevention of short circuit during the further work with the accumulator.
- To weaken a nut on the plug of a negative wire, to disconnect the plug from a negative conclusion.
- To weaken and remove the plug of a positive wire.
- To turn out bolts of a fixing level in the bottom of the battery, to remove bolts and a level.
- To disconnect a plastic hose from the central gas outlet.
- To take out the battery.
- At installation at first to connect positive, then negative wires.
- Without application of force it is almost impossible to mix plugs of wires because the positive conclusion is thicker than a conclusion negative.
- Again to turn on the alarm system and radio.

Care of contacts of the battery
|
|
- To wash crystals on plugs of the accumulator warm water with soda or to process "Leutralol" from Varta.
- To grease conclusions and plugs of a wire with kislotozashchitny plastic greasing ("Ft 40v1" from Bosch).
- Greasing cannot be applied on lateral faces of conclusions and inside of plugs, differently problems with contacts are possible.
