Is jump starting another vehicle damaging to your own battery or electronics? Are sparking jumper cables a bad sight? Should I charge a super dead battery? Should I charge a battery that died overnight? Explanations to those questions, safety tips, and how to properly start jump starting another person's car battery.

Also, don't forget to look into how battery voltage works! Also, make sure your battery isn't dying overnight.

This is one step out of a multi-step series.

Is Jump Starting Bad for Your Battery?

It's possible jump starting your car may damage your car. Current and voltage spikes are common when jumping a vehicle. This is due to the shorting (connecting) of two automotive batteries together without a medium between both components. Note this is an activity that is minimized if you have the right tools such as the jumper booster pack.

I would be careful when considering jump starting if you are using jumper cables. There may not be harm to the good battery's car. However, you don't want to be the one being jumped. Try your best to ensure you take care of your car and take care of your battery before going down this road. Risk is increased the more you are jumped over time.

A lot of clients and homeowners do not comprehend the damages associated with jump starting car batteries. For the most part the process seems harmless. However, deeper inside the system you'll notice electronics going haywire. It's important to ensure you don't jump start the system too often. I suggest finding therapy if you're finding yourself in the same situation again and again. This is because you may need to find professional help with your vehicle in the case you need frequent jump starts. Why that is the case is something to consider.

Of course, you may damage more than just the car's electronics. It's also possible to damage the car battery itself. Batteries are rated at 12 volts. They also don't do so well when connected together. This is due to the fact that batteries shorted together causes a loop of flowing juice to each other. As stated above, you don't want to run into issues with spikes in current. There are plenty of fuses to protect against spikes in current. However, the battery itself is not fully protected in this manner. Your automotive battery is fully naked when you jump start your vehicle. There may be direct damage as a result of the process.

There is more risk if your battery is the maintenance type. Maintenance type batteries are not sealed. As a result, gas may come out and cause a fire risk in the case sparks happen. Take the proper steps to ensure you don't spark the battery by connecting negative to ground and not negative to the negative terminal of the battery. This is a great step towards keeping sparks low to non-existent.

You may need professional help in the case jump starting your car damages the car's electrical modules known as computers. These are especially tricky for a mechanic because they may cause all sorts of false problems. This, unfortunately, may lead to a heftier price tag due to labor charges.

Conclusion

  • It's possible to jump start your vehicle. But, don't do it too often. Don't make it a weekend habit.
  • Damages can occur over the long run. I wouldn't worry too much if you don't do this often.
  • Risk of fire with maintenance-type batteries (be careful about sparking and leaking battery acid gas). Maintenance-free batteries are perfectly sealed and safe from fires.
