Troubleshooting Battery, their causes and remedies

On cars Golf III / Vento established lead-acid batteries, consisting of 6 separate batteries connected in series with each other and placed in an electrolyte (25-30% solution of sulfuric acid, which corresponds to the density of the electrolyte 1,25-1,31 g / cm3).

The battery pack consists of:

- Of a monoblock with the battery compartment;

- Caps with filling openings, closed with a plug;

- Positive and negative plates, respectively, collected in mid-blocks;

- Separators;

- The live baretok with pin-and inter-element bridges serving for the serial connection to the battery pack.

Installed in avyatomobile battery has the following main characteristics:

Rated voltage ................ 12;

Rated capacity, Ah ...... from 36 to 92;

specific gravity (at an air temperature of 25 ?� C):

- The battery is fully discharged - 1.12 g / cm3 (16 ?� C);

- The battery is fully charged - 1.28 g / cm3 (32 ?� C).

On cars Golf III / Vento mounted batteries, ready for work, filled with electrolyte and charged, and are maintenance-free, ie, under normal operating conditions in which the electrolyte refill is not required. However, the following guidelines for the operation of the battery:

- Before servicing the battery put on the apron of canvas or rubberized fabric - it will protect your clothes from splashes of electrolyte;

- Periodically (at least once every two weeks) Clean the surface of the battery cover, as dust, dirt, drops of electrolyte therein lead to rapid self-discharge;

- To clean the battery soak a clean cloth in a 10% solution of soda ash or ammonia solution, then wipe the surface of the battery, and a brush with stiff bristles to clean all the places where it is difficult to get close cloth;

- Then wipe dry with a battery used rags emissions and brush wash with water;

- Check the condition of the pole of the battery terminals. Close-white or greenish patina removed with a cloth soaked in hot water;

- Clean the battery terminals and the terminals for the medium grit sandpaper to a metallic luster;

- After connecting the stripped wire end ferrules with the conclusions of the battery and they both cover the protective film (PVC grease or BTB-1, "Unisma" etc.);

- Complete cleaning of the battery clean and dry its side walls and a bottom;

- Check the electrolyte level, which should not be lower situated on the outside of the battery casing bottom line. If the electrolyte level is below the norm should be refilled with distilled water;

- The battery discharged in the winter by more than 25%, remove from the car and recharge.
