Experts advised the German Technical Inspection Authority to take proper care of the car battery to reduce faults in the winter. To avoid rust and leakage, keep the battery body, electrodes and clamps as clean as possible. Oxides can be removed from above the electrodes with a fine sandpaper and then cleaned with a dry cloth.
Next, apply some grease to the electrodes and clamps, according to the manufacturer's instructions, while the battery body can be wiped with a damp cloth.
On the other hand, German experts recommend before the start of the car to close all equipment, which consume unnecessary current; the modern gasoline engine needs about 400 watts for fuel pump and injection nozzles and engine management.
Systems such as ventilation and air conditioning consume 100 to 500 watts, while heating, lighting and radio consumption is 1,000 watts. The problem is that the equipment consumes more power than the generator can produce, causing the battery to be discharged.
Increased energy requirements also increase fuel consumption. Dynamo needs to generate more current. For 100 watts of electricity, fuel consumption increases by 0.1 liters / 100 kilometers.
