Can you jump start a car with no battery

Boosting is an ideal solution when your car battery dies and you’re in the middle of your journey. However, you need jumper cables and a running vehicle with a working battery to jumpstart your car. What if you don’t have jumper cables or there’s no car in sight and you’re stuck in the middle of nowhere? Sometimes it’s possible to deal with a dead battery without jumper cables. The first step is to keep calm.

This blog post will describe a few valuable methods to get your car back on the road. How you can start your car with a dead battery and without cables depends on what type of car you’re driving: manual or automatic.

Jumpstart a manual transmission car without cables

It’s hard to predict the circumstances in which you have to start your car with a dead battery. Ideally, you should position your car on elevated terrain. The incline will make it easy for you to get the car moving and achieve the required momentum to start your car. However, if the road is flat and your vehicle is too heavy to move, you might need a person or two to push your car.

The extra force will give your car enough momentum. While spare hands are pushing your car, turn on the ignition and switch your car to second gear. Wait for your car to build up some momentum before you release the clutch quickly. In case your car doesn’t start, press the clutch over and over again.

Jumpstart an automatic car without cables

Push start method won’t work if you’re driving a vehicle with automatic transmission. Vehicles with manual transmission are easy to jumpstart without cables. The only method to start an automatic car with a dead battery is to use a portable battery charger. If you drive an automatic car, make sure you have a simple portable charger in your roadside emergency toolkit.

If you have a portable charger and your car battery is dead, all you need to do is plug it in the cigarette lighter and wait for about 20 minutes. Before you go anywhere else, drive to the nearest auto repair shop for a quick inspection.

Call a roadside assistance service

If you’re unable to start your car after trying out all the techniques mentioned above, call a reputable towing company that provides roadside assistance services. It is always recommended to let a professional take care of your roadside emergencies such as a flat tire, dead battery, road accident, etc. Roadside assistance companies provide a range of services ranging from emergency vehicle recovery to boosting.

A dead battery is no-one's idea of fun, but you can still jump a car by connecting the bad battery to a fully charged one using jumper cables.

Here, we show you how to jump start a car, assuming that the charged battery is in another vehicle.

Bear in mind that depending on how dead the car battery is, jumper connections may or may not start a vehicle immediately. After you've connected the two, you may need to start the car with the healthy battery, and spend a few minutes with the two hooked up to give the dead battery some charge. 

It’s also a good idea to read your car’s manual carefully to see if there are any special recommendations to be observed when jump starting. And if you're in any doubt, call AAA or your local roadside assistance, who will have the equipment to get your car running without any risk of damage.

Your Step-by-Step Guide To Jumping A Car

Precautions:

  • Position the vehicles close enough so that the jumper cables will reach easily, but MAKE SURE THE VEHICLES DON’T TOUCH EACH OTHER!
  • Make sure the cables will not be damaged by the fan, drive belts or any other moving parts when the vehicles are started.
  • Make sure the booster battery is the same voltage as the dead one in the vehicle. Nearly all modern car and truck batteries are 12 volts.
  • Make sure the ignition switches of both cars are in the off position, and the transmissions are in Neutral (manual) with the parking brake set, or Park (Automatic).
  • Turn off the lights and other electrical loads on the car with the dead battery, although if it is a modern car with a computer, it’s a good idea to turn on the heater blower motor which will minimize the damage an excessive electrical surge can cause.
  • It’s a good idea to wear safety goggles, because there is always a chance of an explosion and batteries are full of acid.

Make the jumper cable connections in EXACTLY this order:

  1. Connect the red jumper cable to the positive terminal of the dead battery (or jump start terminal on a car with a remote-mounted battery).
     
  2. Connect the opposite end to the positive terminal of the booster battery or jump start terminal.
     
  3. Connect the black jumper cable to the negative terminal of the booster battery or jump start terminal.
     
  4. Connect the other end of the black cable to a well-grounded bolt or bracket on the engine block of the vehicle being jumped, not the battery itself. This prevents sparks near the battery which may cause an explosion.
     
  5. Start the engine of the vehicle with the good battery and let it run at a moderate speed to charge both batteries.
     
  6. Start the engine of the vehicle with the discharged battery.
     
  7. Reduce the engine speed to idle on both vehicles and leave all switches off to prevent damage to the vehicle electrical system.
     
  8. Remove the jumper cables in the reverse order they were attached, making sure to never touch the red and black terminals to each other.

If the charging system and the battery of the car which had to be jumped is in good condition, 30 minutes of driving should being it back up to a full charge.

Remember, sometimes in extreme cold conditions a perfectly functional car may need a boost to get started because batteries put out less energy the lower the temperature, while at the same time need more power to turn in the cold.

Can you jump

A dead battery is just that, dead, there is no residual charge left and more often than not will have a dead cell that drains the other cells of charge continuously. Dead batteries will not take a charge and therefore cannot be jumpstarted.
