The dangers of jump starting
When you find yourself stranded with a dead battery, you might feel tempted to jump start your vehicle. You can either do it from another vehicle, using jump cables, or by using a battery booster pack.
Even though this can get your vehicle back on the road again, you should be aware of the dangers that might follow. It can actually harm the complex electronics in the vehicle, leading to costly reparations and permanent damage to your battery.
In the modern vehicles today, there is over 200 ECUs (electronic control units) with various functions. They perform many different functions such as engine management, controlling of the air conditioning, lights, operation of parking sensors. The ECUs can be viewed as mini-computers in the vehicle and they have a level of about 16 volts. However, if you jump start your lead acid battery it will have a level of 20 volts, meaning that your battery will be shocked back to life. This rapid shift in voltage can easily break one of the valuable ECUs, costing you hundreds or thousands of dollars.
If you jump start a car, the battery booster pack, or if you are using jump leads, the battery on the connected vehicle, works like a power reserve to get your engine started again, briefly bypassing the dead battery. When your engine is running again and you disconnect the booster pack or jump leads, the alternator notices the empty battery and reacts by opening the floodgates to fill it up. This huge amount of power generates a spike in voltage, causing damage to your vehicle.
Jump starting can also have a negative effect on your battery, as the alternator is charging up the battery with more current than it can handle. This causes the battery to heat up, bending the battery plates, leading to the shedding of active material (lead dioxide) and causing a build-up of debris in the bottom of the battery. The damage decreases the efficiency of the battery and will reduce its lifetime, which makes early replacement necessary.
However, there is one smart and easy way to safe-start your vehicle if you have a dead battery. CTEK’s portable CS FREE has patented adaptive boost technology which gets you going again in about 15 minutes.
This process won’t damage the vehicle’s electronics because the CS FREE softly refills the battery and lets you know when it is safe for you to start your car again. When you disconnect the CS FREE, your battery is going to be half full already, which means that the alternator only raises the charge a little bit to power up the battery.
The CS FREE is also a 4-in-1 unit. It is both an adaptive booster, a battery charger, a smart maintainer and a high-tech power bank. If you also use your CS FREE to regularly charge and maintain your battery, you can extend the battery life up to three times.
You can find more information about the CS FREE, which is compatible with all types of 12V lead-acid battery as well as lithium (12V LiFePO4) batteries, here.
