Will a Jump Starter Charge a Battery? Jump Start Battery Pack

If someone has a dead battery and jump-starter or a jump start cable also, many times people think they can charge their dead car battery using these. Even you might have thought of this once but the answer to this question is a bit different. 

No, the jump-starter does not charge the battery, it helps the car battery to get to a state where it can recharge itself or revive its battery on its own. Now you must be thinking then what is its real use and what is the whole procedure of making your dead battery work again after jump-starting it.

So here we will help you to understand the complete step by step process which makes your battery work again.

Step 1: Recognising The Status Of Battery

Yes, the very first step should be while going through other successive steps to check properly where the battery is dead or not. This is because if we do not take care of this thing on the primary level, then jump-starting a non-dead battery may result in its failure forever or may blast the battery since we apply a very sudden and high ampere current while jump-starting the car battery. This may also cause injury to us so it’s better to take care of this step before all other ones.

Step 2: Knowing The Batteries Requirement Of Current for Jump Start

Before going through the process of jump-starting one should correctly know the right amount of current the battery will need to jump-start it by checking the weight and size of the engine of the car. Although, there are some other factors also which tell how many ampere currents our car battery needs. These two factors are the primary ones.

Step 3: Jump-Starting The Car Battery

Now as we know how much ampere current should we apply to our battery we should start the process of jump-starting the car battery. For this following are the steps:-

  1. Turn off the car’s ignition.
  2. Remove the dirt or corrosion if present around the car battery’s clamps of voltage points.
  3. Now identify the positive and negative terminals of the battery and carefully join the positive and negative terminals to the cable.
  4. Firstly join the positive of the battery to the positive of the starter and the then negative terminal of the battery to the negative of the starter.
    *Make sure the starter is switched-off while joining these terminals.
  5. Now switch on the starter for some time.
  6. After this, you can try to restart the car. Do not chunk it for more than 4-5 seconds. If it does not start at once try another chunk after 2-3 min wait.
  7. If the car does not start even now then there might be some problem with the battery.

Step 4: Running The Car after Jump-Start

After jump-start, if the car starts we have to take it to the road and run it for about 10-15 mins or for a minimum of 2000-25000 RPM to revive the engine. After taking this ride turn-OFF the ignition, then you should wait for about 10 seconds and then again turn-ON the ignition. If the car’s engine starts then the battery charging of the car is successfully over now.

Why is this running process performed?

When our battery has fully discharged the work your jump-start does is to provide energy to the engine to start the engine because the only work primarily your engine does is to start your engine. As your engine starts, the alternator performs the further work of recharging. The alternator is the electrical powerhouse of the car, it generates electricity by its turning which helps to recharge the engine up to an extent after which we can properly charge it by some other charger. The Alternator not only charges the car’s battery but also it’s other devices like radio, AC, etc.

So this is why it’s important to run the car after jump-starting it to revive the engine and recharging the battery by itself only.

Conclusion

The jump-start cannot charge our battery engine. Our battery’s work is to give power to the engine for starting it. After that Alternator generates electricity and charges the battery. Jumpstart just provides that initial start to the engine so that it can revive its engine power and recharge itself because it is dead up to that point so that it can get that initial start.

Frequently Asked Questions

Q1. Can we recharge a completely dead battery?

Every battery has a shelf life of about 3-5 years. If this shelf life of your car is over then there will be no possibility to charge this same battery.
But if the battery is present in the discharge state because of leaving the headlight “ON” and under the period of its shelf life then it can surely charge the battery by jump-start.

Q2. What are the precautions should we take in the whole process of starting the engine from jump-start to charging the battery?

Here are some precautions that one should take while charging a dead battery
1. Identify the dead battery properly whether it is dead or not, since it may lead to the explosion of the battery.
2. Provide Ampere current according to the need for jumpstart of the battery.
3. During jump-start, the initial ignition of the car should be “off”.
4. The negative and positive of the battery should not join each other.
5. Chunk the ignition for 4-5 seconds only, not more than that.
6. Wait for sometime if the car doesn’t start at once.
7. One should run the car near a place which is safe and where we can jump-start the car in an emergency.

Q3.Which is better a portable s type jump-starter and lithium battery?

A portable s-type jump-starter is anytime much better than a lithium battery to jump-start a battery because of the following reason
 1. A portable s-type jump-starter is portable so we can take it anywhere with us for an emergency which is not possible with a lithium battery.
2. A portable s-type jump-starter is more reliable in comparison to a lithium battery for jump-start as it provides sufficient start to the engine.
3. The portable s-type starter is much safer as it has very little possibility of bursting while jump-starting the car.
