1. Can you damage your Mercedes-Benz electrical equipment by jump starting?
The short answer is yes, and it is actually likely if not done properly.
There could be 3 reasons why electrical equipment in a car fails upon jump starting. Some possible causes include:
1. Power surge: Jump starting a car can cause a sudden surge of electrical power, which may exceed the capacity of certain components, leading to failure.
2. Incorrect polarity: If the jumper cables are connected incorrectly, such as reversing the positive and negative terminals, it can cause damage to the electrical system.
3. Pre-existing issues: If there were pre-existing electrical issues in the car, jump starting it could exacerbate those problems and cause failure.
Methods:
1. Installing a new battery: this is when you know your car battery is more than 4 - 5 years old and it is approaching the end of its life cycle. Probably the green indicator on the battery is only white the best solution is to replace your battery with a new one. And using this method your Mercedes absolutely will love it as there are many issues like ABS, top convertible and fault code related issues that can be eradicated by only replacing the baatery.
3. using a charger to trickle charge your battery if you have time this a great method of you are sure tbat your battery is healthy and it is only flat due to leaving a light over night...
2. Using a good jump starter... portable Jump starters these days are so advanced in technology and they are designed to produce steady amount of power to quickly and efficiently crank the engine to avoid a power surge and consequently they can safely start your car. By using a high quality jump starter you actually eliminate the risk of electrical damage to the running car and you also do not need to carry a jump start cable.
4. Using a donor vehicle... this is probably what comes to mind first, but it should be actually your last option as there are better methods as mentioned to start your car. To use this method in case of an emergency if you are stranded and you do have access to a pair of good quality jump cabales, and a donor runing vehicle,
1. Bring both vehicles battry as close as possible to each other.
2. Make sure the ignition of both car are off and all and turn off all electrical components.
2. Always start with attaching the positive cable to the dead battery's positive pole.
Double check the polarities, make sure the red and black cables dont contact.
3. Connect the positive cable to the running car.
4. Connect the negative cable to the negative battery trminal of the runing car.
5. Last step is to connect the negative cable to a good ground on the engine bay area of the dead car. For this step you want a good and thick connection and as much possible you should avoid arching and sparking or a loose connection. Do not connect direcly to the battery as even the dead battery can emmit flamable hydrogen and prodcing archig or ignition can be dangerous. Stay at least 30cm from battery and fuel lines.
Make sure the cables are away from fan and belts and moving parts of the engine.
6. Start the runing car and let the dead battery to charge for at least 15 min, 30 min is ideal as the battery can be charged as much as 15 Amp hour in 30 min.
7. Proceed starting the dead car, hopefully the engine would start at this time safely, remember not to shut off the engine for at least 30 min so the battery can get some charge for the next start.
so now how to avoid dead battery situations?
1. Check the voltage of your battery time to time with a multimeter, making sure that it holds more than 12:56v after 15 min of shutting the engine. If the voltage is low and your battery is older than 4 years old, replace it.
2. Keep the battery terminals clean and free from corrosion.
3. Make sure your charging system is in a good condition when the engine is running a healthy voltage of 13.8 to 14.1v should exist.
3. If your car only travel short distances on daily basis or if it is only used few times a year, connect a trickle charger to it and charge it monthly.
