General information

The battery is one of the most important electrical components in the modern automobile. A battery that provides trouble-free service has a great influence on customer satisfaction. To ensure trouble-free service and optimum service life, batteries must be checked, serviced and maintained as per the instructions in this information.

Apart from starting the engine, the battery has other tasks. It acts as a buffer and also supplies electrical energy to the complete vehicle electrical system. In addition, the cyclical and capacity demands on the battery have increased due to additional safety and convenience features (electrical consumers) being installed.

The automobile battery has undergone many technical changes and improvements, and development of new battery technologies continues.

A new generation of maintenance free batteries uses physically and constructively optimized, lead-calcium coated positive electrodes. Advantages include minimal electrolyte consumption and servicing requirements, as well as improved charge stability over a longer period of time. Simplified checking of these batteries is also achieved with the charge indicator (magic eye).

Several different types of battery may be installed. Each requires specific servicing.

Electrolyte level - batteries with sealing plugs, checking

Special tools, testers and auxiliary items required

Scheme 16

1. Battery filler bottle VAS 5045

Scheme 17

1. Hydrometer (commercially available)

The correct electrolyte level is an important factor in ensuring long battery service life.

1. On batteries with visible min. and max marks it is sufficient to perform visual inspection from outside to check electrolyte level.

1. The electrolyte level must be above the minimum marking but not exceed the max marking.

1. On batteries on which the min. and max marks are difficult to see, or on which the electrolyte level cannot be seen because of the opacity of the battery housing, remove the sealing plugs.
2. Check the electrolyte level by making a visual inspection of the inside of the battery.

1. The electrolyte level must coincide with the internal level mark (plastic web). This corresponds to the max marking on the outside.

Electrolyte level too low

If the electrolyte level is too low, drying-out of the cell plates will reduce the capacity (power) of the battery. The cell plates must be fully covered by electrolyte (sulfuric acid/water mixture) in order to prevent corrosion of plates, plate bridges and cell connectors. Such corrosion would impair battery operation and make the battery unusable.

Scheme 18

1. If electrolyte level is too low, use battery filler bottle VAS 5045 to add distilled water until max mark is reached.

Note. Filler neck of battery filler bottle VAS 5045 is designed to prevent over-filling of battery cell and electrolyte spills. When the maximum filling level is reached, the flow of distilled water into the battery cell is cut off. Use distilled water only, this prevents contamination of the battery electrolyte and the associated increase in self discharge. Screw sealing plugs of battery cells back in again.

Electrolyte level too high

If the electrolyte level is too high (overfilled), escaping electrolyte (sulfuric acid/water mixture) will cause damage outside the battery.

1. If the electrolyte level is above the inner level mark (the plastic web) or the outer max mark, it is essential to drain some off.
2. Remove the battery cell sealing plugs.
3. Use a commercially available hydrometer to drain off the sulfuric acid until it has fallen to the level of the plastic web or the max mark as appropriate.
4. Screw sealing plugs of battery cells back in again.

Electrolyte specific gravity - batteries with sealing plugs, checking

Special tools, testers and auxiliary items required

1. Hydrometer (commercially available)

Note. The electrolyte specific gravity test in conjunction with the battery test provides specific information on battery condition. The temperature of the battery electrolyte must be at least 10 ° C. Electrolyte specific gravity can be checked immediately after charging battery.

Test sequence

1. Remove all battery plugs (battery cell sealing plugs).

Scheme 19

1. Immerse end of hydrometer in a cell and extract sufficient electrolyte so that float swims free in the electrolyte.

1. The greater the specific gravity of the electrolyte drawn in, the higher the float will ride.
2. The specific gravity in kg/dm 3 (specific gravity of electrolyte) can be read off the scale - arrow - on the hydrometer.

1. Take reading on hydrometer and compare to values given in table

The specific gravity in normal climatic zones must be at least 1.24 kg/dm 3 . If specific gravity is too low in all battery cells

1. Charge battery and then repeat electrolyte specific gravity test.

Example 1

* specific gravity in cell 4 is too low (deviation greater than 0.03 kg/dm 3 )

Example 2

* specific gravity in cells 4 and 5 is too low (deviation greater than 0.03 kg/dm 3 )

If specifications are not obtained

1. Replace battery.

Note. The measured values for the electrolyte specific gravity of the individual battery cells must NOT deviate by more than 0.03 kg/dm 3 , otherwise battery has to be replaced. Reinstall battery sealing plugs.

Battery, testing

Note. In order to better determine a batterys overall condition, it is recommended to always perform the battery test in conjunction with the electrolyte specific gravity test Always follow the battery tester operating instructions. It is not necessary to remove battery from vehicle or disconnect battery terminals.

1. Adjust charging rate according to battery capacity (refer to Midtronics INC-940 Instruction Manual).

Charging totally discharged batteries

1. Batteries which have not been used for lengthy periods, e.g. in vehicles which have not been driven, are subject to self-discharge.
2. A battery is considered to be totally discharged if the no-load voltage has dropped below 11.6 V. Initial battery damage can occur between 12.2 and 11.6 V. Measuring no-load voltage --> «No-load voltage, checking»(/audi/a4/b6-2000-2006/remont/cruise-control-systems/#electrical-equipment__no-load-voltage-checking) .
3. In a totally discharged battery the electrolyte (sulfuric acid/water mixture) is reduced to almost all water, as the sulfuric acid content is heavily reduced. At temperatures below zero, the battery may freeze and the cause the housing to burst.
4. Totally discharged batteries become sulphated, i.e. all the plate surfaces of such batteries become hard. The electrolyte has a slightly milky appearance (instead of being clear).

1. If totally discharged batteries are charged directly after being discharged, the sulphation dissipates.
2. If this is not done, the plates become even harder and their ability to absorb charge is impaired. This results in reduced power output.

Procedure for charging exhausted batteries (sulphated)

Totally discharged batteries (that are also sulphated) must be charged as follows using a low charging current

1. Set charging current to approx. 5 % of battery capacity, i.e. for a 60 Ah battery the charging current is approx. 3 A.
2. Charging battery --> «Battery, charging»(/audi/a4/b6-2000-2006/remont/cruise-control-systems/#electrical-equipment__battery-charging) .

1. The charging voltage (U max ) must not exceed 14.4 V.
