Bring Dead Battery Back to Life-Methods and Possibility

Many people are often confronted with the problem of a faulty battery that refuses to start their vehicles. A dead battery is a tricky problem, especially if you are in a hurry. So, is it possible to recharge an entirely dead battery?

There are a few methods to recharge your battery, but the word "completely dead" is a little more challenging to assess. If your car doesn't start due to a completely dead battery, your only alternative may be to acquire a jump start from another car and get a new battery soon.

In this post, we'll look at whether or not a dead battery can be revived. And also the potential methods to do the same. 

First Thing First,

Can a dead battery be brought back to life?

Yes, a dead battery can be brought back to life, but it might not have 100% capacity. You may see a fall in productivity. So now you know you can get dead batteries back to life, let's jump in the next part on the same methods.

How do you bring dead battery back to life?

When someone claims their battery is dead, they usually mean that it has been discharged. This indicates that the battery's voltage is less than a functional level. Batteries typically operate at an operating voltage of 12 volts or higher, and if the voltage drops below that level, you may have a dead battery.

A battery serves five purposes, and if yours isn't working properly, you should check its voltage. If the voltage is just slightly lower than it should be, this is an easy remedy. Your car's alternator makes it possible to charge your battery. The battery is in charge of supplying the power required to start your vehicle. When your car is operating, though, the alternator is recharging the battery in preparation for the next start.

Driving around may be all that is required to repair a dead battery that still has a reasonable level of power. As previously stated, the alternator will recharge the battery while your vehicle is in motion. To ensure that this works as well as possible, you should avoid utilizing any automotive features that require battery power, such as air conditioning, radio, and TV.

Driving about for half an hour can raise the voltage in your battery to a safe level. However, if this is not solving your problem and you continue to have problems, there are more steps you can take.

If you observe that the voltage in your battery is significantly lower than it should be, you should try a different approach. It's possible that you won't even need to check the voltage. If your car does not start after you turn off the key in the ignition, you most likely have a dead battery. Jump-starting your car is an efficient way to resolve this issue.

Jumper cables and another vehicle are required to jump-start a car. The wires are connected to the battery of the second car, as well as your battery and a clean piece of metal under the hood of your car, once all necessary safety precautions have been taken. While the second car is running, the cables will transmit power from the alternator of the second car to your car's battery, and your battery should have enough power to start your car after a few minutes.

How do you bring lead acid batteries back to life?

Now we will learn how to bring dead sealed lead acid batteries to life again. This procedure has been tried and tested on a large number of dead and expired batteries, with 90% of them working again.

P.S: This method may not restore the battery to full functionality, but at my rate, it will operate for 50% to 70% of its previous capacity.

Materials you Need:

●3cm Syringe

●Crocodile Cords "Used With Psu "

●Voltmeter Or Multimeter

●Battery Charger Or Power Supply

●Distilled Water

Note: Please always keep safety precautions in mind by using goggles and chemical gloves.

Let’s begin with the steps on how to bring dead acid batteries back to life.

Step 1: Preparing the Battery

First, take your sealed acid battery, and there you will see a flat cover. Just remove that and now measure the volt of the battery using a voltmeter.

Step 2: Fill the Battery with Water

Now, in this step, you will need to fill the battery with DIstilled water to activate the acid again. To do so: Refill the battery holes using a syringe till the water comes out of all the holes.

Step 3: Mix Water With Acid and Charging

Now fill the battery with water, and we must ensure that it is mixed with dried acid inside the battery in order to reawaken it. To begin, you must provide a 12 Volt DC supply to charge the battery.

Notes: 

●If no bubbles emerge from any of the holes, you must reverse the negative and positive and wait 13 minutes. At Maximum (this is a dangerous step; do not leave the battery in this state alone)

●If you see bubbles coming out of holes too quickly, as if they are boiling, turn off the power immediately and reconnect the negative and positive wires.

Step 4: Clean the Battery

Finally, use the syringe to remove the wastewater from the top of the holes and charge the battery. Please don't cover the holes until it charges to 6.9V; check it every 1 hour after that, then dry it off with a tissue and cover everything.

Congratulations, your battery is now operational!

Final Thoughts

It is feasible to revive a dead battery, and depending on the situation, a dead battery is usually a straightforward fix, whether you are stuck in your garage and can manage it by yourself or you are in the middle of nowhere and require professional, rapid, and efficient service in the blink of an eye.
