VOLKSWAGEN POLO LIM IN 2011 (01) PDF Document

To ensure long use of the battery, the battery must be checked, serviced and maintained according to the specifications in this manual.

The description for these batteries is for maintenance-free batteries. No stickers may be removed and do not replenish with distilled water. Only perform a visual check.

Batteries where the magic eye is colourless or light yellow must not be checked or charged. Do not slave/jump start the vehicle! These batteries must be renewed.

Absorbent glass mat batteries are identified by the abbreviation AGM on the battery.

Always replace an absorbent glass mat battery with another absorbent glass mat battery.

1. Fires, sparks, naked flames and smoking are prohibited when handling batteries. Avoid sparks as well as electrostatic discharge when working with cables and electrical units. Avoid short circuits. Therefore never lay a tool on a battery.

2. Wear eye protection before commencing work on battery.

4. Disposal: old batteries are classed as hazardous waste. They may only be disposed of through a suitable collection centre and only in accordance with respective legislation.

5. Never dispose of old batteries in household waste system!

6. There is a danger of an explosion when working with batteries. A highly explosive gas is produced when batteries are charged.

8. Battery acid is very caustic; therefore wear eye protection and gloves when working with batteries. Do not tilt battery. Acid can leak out of the gas vents of some batteries.

The battery clamps should only be fitted by hand and without using force.

Battery terminals should not be coated with grease.

The battery clamps should be fitted so that the battery terminal is either flush with the clamp or protruding from it.

Once the battery clamps have been tightened to the specified torque, the threaded connections should not be tightened any further.

Carry out the procedure in sequence as follows:

1. Visual check.

2. Check colour display of “3-colour” magic eye or “2-colour” magic eye.

3. Perform a battery load test using battery tester with printer -VAS 5097 A- or -VAS 6161-.

4. Depending on the result of the battery test, perform current draw test.

Carry out the procedure in sequence as follows:

1. Visual check.

2. Perform a battery load test using battery tester with printer -VAS 5097 A- or -VAS 6161-.

3. Depending on the result of the battery test, perform current draw test.

It is essential to visually inspect the external condition, to check the terminals and to ensure proper attachment of the battery before performing extensive tests.

The battery will be damaged if the battery is not secured correctly.

Vibrations shorten the life of the battery, there is a danger of an explosion, the cell plates may be damaged and the clamping bracket may damage the battery housing.

Check battery is securely seated, if necessary tighten securing bolt to specified torque.

If battery housing is damaged: Electrolyte can leak out if the housing is damaged. If battery acid leaks out, serious damage to the vehicle could be caused. Treat components affected by leaked battery acid immediately with acid neutraliser or a soap solution.

Check whether the battery terminals (battery wire connections) are damaged. The necessary contact on the battery clamps cannot be guaranteed if the battery terminals are damaged. When connecting the battery clamps, tighten the battery clamps to torque specified in this workshop manual “Electrical system” for the respective vehicle. If the battery clamps are not correctly seated and tightened, the wiring may burn. Which will cause malfunctions in the electrical system. Therefore it can no longer be guaranteed that the vehicle will function correctly.

Before carrying out a visual check, tap the magic eye lightly and carefully using the handle of a screwdriver. The air bubbles, which can influence the display, will dissipate when doing this. The colour display of the magic eye will therefore be more accurate.

Three different colour displays are possible:

»Green«, battery is charged sufficiently.

»Black«, battery partly discharged, charge state < 65 % or completely discharged.

»Colourless or light yellow«, battery must be renewed.

Three different colour displays are possible:

»Black«, electrolyte level is OK.

»Colourless or light yellow«, electrolyte level too low. The battery must be renewed.

It is not necessary to remove or disconnect battery when using battery tester with printer -VAS 5097 A-.

If the battery is OK, the voltage value drops only to the minimum voltage.

If the battery is defective or has a low charge, the battery voltage quickly drops below the minimum voltage.

After the test is completed, this low voltage value remains over a longer period, and the voltage increases very slowly again.

Perform test once only. Repeating the test falsifies the result.

The tester requires approx. 30 minutes to cool down before carrying out another test or testing another battery to ensure the results are not falsified.

For battery tester with printer -VAS 6161-, the current draw test must always be performed when the test result „Perform current draw test“ appears on the display.

The current draw test must be carried out when the test result with battery tester with printer -VAS 5097A- is as follows:

1 – Starting output sufficient

2 – Starting output poor

3 – Starting output very poor

4 – Cannot be tested – charge battery and repeat test.

and when the tester will not switch on (no LED, no printout)

Performing a current draw test whilst charging a battery will quickly establish whether a partly or fully discharged battery can be recharged to return it to a serviceable condition.

When charging a battery, battery temperature must be at least ≥ +10 °C.

The charger must be capable of outputting a charge current of at least 30 A, as for example with VAS 5095A, VAS 5900, VAS 5903.

The battery’s current draw must be measured with a current pick-up clamp, e.g. VAS 5051B/7, when charging with battery charger -VAS 5095A-. Battery charger -VAS 5900- and battery charger -VAS 5903- display the current draw on the unit.

Connect battery to battery charger and start charging sequence.

Measure charging current of battery after 5 minutes.

If the current draw A is higher than 10 % of the nominal capacity (e.g. > 6.1 A for a 61 Ah battery), fully charge battery and test again.

If the charge current, in amperes, lies below 10 % of the nominal capacity after 5 minutes of starting the charging sequence, renew battery. For Guarantee and ex-gratia cases: complete battery test sheet and keep it with the battery.

The battery must not have been charged or discharged within the last 2 days.

Check battery no-load voltage with hand multimeter -V.A.G 1526 B-.

A battery is designated „totally discharged“ when the no-load voltage is less than 11.6 V.

Totally discharged batteries freeze prematurely.

Frozen batteries should no longer be used.

Batteries that have not been used for a long period of time discharge themselves, e.g. those fitted in stored vehicles.

In totally discharged batteries, the electrolyte is comprised almost entirely of water because the acid content is so low.

Totally discharged batteries sulphate, that means, the entire plate surfaces of the battery harden.

If a battery is recharged shortly after it has totally lost its charge, the sulphation will mostly dissipate.

If these batteries are not recharged, the plates continue to harden and the ability to recharge is reduced. The result of which is a reduction in the battery output.

Check battery no-load voltage.

The functions of the cruise control system are controlled by the engine control unit.
