Car battery repair

How to choose a Bosch battery for your car?

Turning to the repair of the car's battery, the owners complain about the occurrence of malfunctions even before the expiration of the warranty period. This may be due to an incorrectly selected battery. The fact is that modern cars have much more electronics. These include the start-stop system, braking energy recovery systems and other energy-consuming on-board devices. Special models of Bosch batteries, for example, S5A (AGM) and S4E (EFB) are able to withstand more start cycles and are more powerful. They are more expensive, but they give you the following advantages:

• stability of launch;
• battery longevity;
• the efficiency of the electrical system of the car.

Diagnosis of the state

Almost no one checks the level of charge until the machine stops start. However, regular repair and maintenance of car batteries will help not only to prevent the failure of work, but also to maintain the battery life for a long time. Bosch Car service offers checking and maintenance of batteries based on its own service station at a time convenient for the customer. You can evaluate the battery by yourself using  C3 or C7 chargers from Bosch, which can be purchased at any of Bosch's authorized technical centers. With the help of these devices, you can recharge the battery without resorting to service.

Reasons for battery breakdowns

The cause of the failure of the car battery can be not only its malfunction, but also the problems in the operation of the associated equipment. Repair of the vehicle's battery should begin with a complete diagnosis of the condition of all systems in order to exclude other problems that cause its discharge. Loss of efficiency of the battery can occur not only because of long-term storage. Other reasons are presented in the diagram:

The phenomenon of instantaneous discharge, characterising by instantaneous battery discharge, can be caused by any of these reasons. Remember, you can not leave a fully discharged battery for a long time - this will lead to irreversible damage, namely, a rapid drop in power, impossibility of recharging.

Problems of launching in winter

Experienced motorists know that by the winter it is necessary not only to change the rubber, but also to check the condition of the battery. Repeatedly recharging and "lighting-up" is better even replaced with a new one, so that in the cold you can not stay without a car and with a bunch of problems in addition - with filled  candles, for example. Strange as it may seem, with the manifestation of problems in winter, the battery itself loves the cold. High temperatures during the summer period will more likely cause a waste of capacity than frost. What's the matter? The problem is that in winter the viscosity of the engine oil rises, which increases the load of the engine at the moment of start. A greater consumption of energy and leads to a rapid deterioration of the battery.

Symptoms of a discharged battery

Assessment of the battery condition is carried out in appearance and indications of indicators, both in the car's interior and on the outer panel of the battery. Repairing the car's battery or its maintenance is required if:

• the indicator on the dashboard in the passenger compartment does not burn;
• the indicator on the dashboard in the passenger compartment does not light;
  The charge indicator on the battery itself lights up black or white;
• on the plates AKB seen appearance of light gray plaque;
  there was a change in the color of the electrolyte to violet or earthy brown;
• hear the clutching of the starter at startup;
  noticeable loss of headlamp power after the engine is switched off;

You can check the battery performance with a hydrometer, tester or multimeter.

• Repeated charging of the battery

  Chargers C3 and C7 from Bosch allow you to replenish battery power without resorting to  service. They are equipped with a built-in tester that determines the level of charge and is able to control the amount of charge your battery can accept. They are universal, suitable for batteries of different capacities, type and brand.

• They allow you to make a charge without removing the battery from the car, which is convenient for women, as well as is actual for high-capacity cars. When the charger is in operation, the contacts remain de-energized if the connection to the terminals is incorrect or absent. Start of work is given by one button.
