Professional battery service

How about a free battery check?

Have you any idea about the current state of your battery? Most drivers probably do not give it a thought until they have a breakdown or their vehicle refuses to start. But if you have a battery check performed regularly at one of our workshops, we will always replace it when necessary. Advantage: It is better to spend a few minutes having a top quality Bosch product fitted rather than waiting hours for the breakdown service to arrive.

• Bosch battery S4 (12 V, 60 Ah, 540 A)

Winter leaves our experts cold.

As soon as the weather turns cold your can hear and see it everywhere: Stuttering starters and stranded vehicles. A weak battery is usually the cause of the problem, as chemical processes slow down at low temperatures and greater frictional resistance occurs in the engine. Bad news for any starter battery – particularly when the alternator is not operating.

As if that were not enough, modern vehicles are fitted with ever more demanding electronic equipment – from start/stop systems right through to a variety of electrical loads. Which means that car batteries are increasingly becoming the domain of experts. And so we would urgently advise drivers never to change the battery themselves unless they have the necessary technical knowledge. It is always best to leave maintenance and replacement to the experts at our workshops – both in summer and winter.

A helping hand for weary batteries

Starting assistance can give a boost to weary batteries. But before you connect up your car to another vehicle there are a few important points to consider:

The rated voltage of both batteries must be the same (e.g. 12 V). There must not be any contact between the bodywork of the two vehicles. After switching off all electrical equipment, connect the red jump lead to the positive post of the flat battery and then to that of the full battery. Then connect the black cable to the negative post of the full battery before connecting the other end to a metal surface in the engine compartment of the vehicle with the flat battery. Important: Never connect it to the negative post of the flat battery as otherwise there would be an acute risk of explosion. Only then should you attempt to start the vehicle.
