A battery can also last less than three years in some cases. Some probable reasons may be due to shortage of Usage, fewer electrolyte stages, extreme draining and charging, decay, charging difficulties, or chambers may be broken.

Like, going to long-distance places or an unknown location, you must check whether your car battery is in good shape or not. You may have to face a problem if you did not check, and it stops in the middle road.

It is always best to check before going to such places. You must also keep a backup because even a good one may stop or become dead unexpectedly for any reason, which may cause your problem.

However, you must have minimum knowledge of a car battery and specific parts to do these types of repairs. Otherwise, you must take help from a car expert. Nearly all repairing techniques need the use of definite gears and resources. These required resources are stated below:

  • Purified Liquid
  • Magnesium Sulfate(MgSO4∙7H2O)
  • Wedge
  • Spindle
  • Acetylsalicylic Acid(Aspirin)
  • Cable
  • Rotary Tool
  • Petrol Saw
  • Battery Cable
  • Igniter

There are some alternative techniques you can use to revive your dead car battery. They are explained below:

Magnesium Sulfate(MgSO4∙7H2O) Usage

The battery may also stop working due to fewer electrolyte stages. It can be solved by creating an electrolyte mixture using magnesium sulfate. Another widely used name of magnesium sulfate(MgSO4∙7H2O) is Epsom Salt. So, you must check the battery before to see whether the problem is created due to low electrolytes or not.

In the case of low electrolytes, it is seen that Epsom salt may supply adequate charge to help to revive the machine again. Magnesium Sulphate is a powerful acid. It contains a range of hydrates, which helps to stabilize the compound.

The main procedure to create an electrolyte mixture using magnesium sulfate is given below:

First, you need to melt one portion of Epsom salt with three portions of hot filtered liquid to create an electrolyte mixture using magnesium sulfate. You have to pour separately in each chamber until the chambers are enclosed by one-fourth to half electrolyte mixture.

Durable Pointer Moving Technique

The durable pointer moving technique is mostly known as the “Hand Cranking Technique.” The way this technique work is given below:

This technique needs a spindle(axle stand) and back wheels to toughen the vehicle under maintenance. The forward-facing steering wheel must be fixed firmly at the core and right-angled to the tire.

When the lighter is on, the car must be in the 5th gear position. You must cover the cable near the drive tire while rotating the vehicle wheel in the usual way of its turning. Afterward, you have to try very hard to start working the machine and motor.

Usages of Aspirin Mixture

You can also use an aspirin mixture to recover your dead car battery. For that, you need to make a mixture by using filtered liquid and Aspirin.

The main procedure to create an aspirin mixture is given below:

  • Firstly, To make this mixture, you have to break 12 aspirin tablets of 350 mg or 500 mg.
  • Secondly, you have to pour the powder mixture into 6 ounces of hot filtered liquid.
  • Finally, you have to pour equally in each chamber until the chambers are entirely enclosed with it.

Petrol Saw Technique

The Petrol Saw technique is mostly known as the “Chain Saw Technique”. This technique enables a chainsaw usage to charge the battery by moving the generator (situated on the machine).

The procedure this technique work is given below:

Firstly, you need to take out the shackle, edge, and radiating bars for support.

Secondly, you have to take out the belt drive from the generator. It will look like a lifter.

Then, you can attach the chainsaw axle and the generator steer lifter by using the belt.

However, by giving mild force, you can involve your drive belt and then initiate the chainsaw. It would be best if you kept it working until it begins to recharge the car battery.

Although this mechanism works well, it is dangerous to apply. Because moving belts can move at a very high speed, making it unsafe.

That’s why you need to take additional measures and convinced enough if you want to follow this technique. Otherwise, it is recommended not to use these techniques.

Filtered Liquid Usages:

Pouring filtered liquid into the cell helps to immerse the section, facilitating a new reaction that causes the machine to work. If the battery stops due to fewer electrolytes, then it will be beneficial in this case. It only can be used as a substitute if there is no Aspirin or Epsom salt with you.

Rotary Tool Technique

The rotary tool technique is the Usage of the drill battery system, which maybe 18 or 20 volts. Its working mechanism is like a spring.

The procedure this technique work is given below:

It would be best to have a completely charged 18-volt drill battery(mostly) and alternating current(AC). You can purchase from any car garages If you don’t have these things.

You can temporarily link your dead car battery to the drill battery along with the alternating current. This process lets the 18-volt drill battery merge with your car’s dead battery to make it work again.

Warm Residues Technique

This technique can be used as the last option if either of the above-stated methods does not work. It works in the following way:

Firstly, using a lighter or anything that causes a fire, you have to burn something to make hot ashes. Secondly, you need to take away the discharge cover situated above the battery. You need to take it outside the car and place it on the warm residues.

You need to very cautious that the fire doesn’t spread in any other place. The warm residues will make the battery hot. Finally, reassemble the battery into its place correctly and then try to see whether it is working properly or not.

So, these are the techniques that you can resort to anyone to recover your dead car battery within the shortest time. However, all of these repairing techniques need to be done with extreme caution.


I hope this article helped you know how to revive a dead car battery. If a car battery stops working, then you can not start your car. You can try any one of the above-stated repairing techniques to avoid facing these types of problems while traveling to any place. Because while traveling, if your car breaks down suddenly and you don’t know what to do, then your happy moment may turn into a bad dream.
