I got stranded in a deserted highway because of a weak battery once, and the first thought that entered my mind was “how to jump start a car battery without another car?” Since then, I’ve been wiser, and I’ve learned not to be caught in such a distressing predicament again.
How do you boost or jump a car battery without help from another vehicle? If your car has a manual transmission, the easiest and simplest way to jumpstart a car battery is to give the car a push. For cars with automatic transmission, however, you will have to use a portable jump-start battery to do it.
Methods Of Giving A Weak Car Battery A Start
Push the car
The most uncomplicated way to give a car battery a start without jump starting it is to push the car until it has gathered momentum. All you need to do is switch on the ignition, shift to 2nd gear, and give the car a good push until it gains some speed.
Once the car has picked up speed, let go of the clutch pedal. At that point, the engine will be sufficiently fired up by the transmission for it to start. But, this method does not work for all cars, but only for those with manual transmission.
Jumpstart the battery with the battery of another car
For cars with automatic transmission, an effective way to give its weak car battery life is to jumpstart it with a healthy battery from another car. It is a simple and straightforward procedure. All you need are jumper cables and a working battery from another car.
Here is how it goes:
Step 1– Set the two cars on park front bumper to front bumper or side by side
Step 2 – Connect the terminals of the two batteries with the jumper cables
Step 3 – Start the engine of the car with a healthy battery and allow it to run for several minutes.
Step 4 – Start the engine of your car. At this point, your battery must have received enough juices from the donor battery for it to start. If it doesn’t turn on, continue the charging it from the working battery of the other car. Revving the engine of the donor car will be a great help.
Step 5 – Once your engine is running, disconnect the jumper cables connecting the two batteries.
Step 6 – Build-up the charge of your battery by driving it. At this point, the alternator takes the task of charging it.
