How To Recondition A Lithium-Ion Battery – Detailed Guide

Have you ever considered how important batteries are? Not really, I guess. It’s just a matter of taking them for granted. When our gadgets and devices don’t work well, we think, “maybe the battery is bad.” Most likely, this is the only time we think about them. The cost of replacing batteries can be high. Here are some tips to help you save and reuse those old batteries that you no longer need. So don’t worry, In this article i am going to tell you how to Recondition a lithium-ion Battery. Just follow all the methods given below to give a new life to your old batteries.

What Are Lithium-Ion Batteries?

As a key component of its electrochemistry, lithium ions make up a lithium-ion battery. Anode lithium is ionized, and its electrons are separated during a discharge cycle. After traversing the electrolyte, they recombine with their electrons at the cathode, where they are neutralized. Between the cathode and anode of the battery, there is a microporous separator where lithium ions pass through. A Li-ion battery has a high level of voltage and charges storage per unit mass and volume due to its small size (third only to hydrogen and helium).

Lithium batteries are particularly advantageous because they do not release harmful gases, such as carbon monoxide and hydrogen. Furthermore, lithium ions have a tight bond to each other. Because of this feature, lithium batteries last along. Also, these batteries hold about three or four times the energy as alkaline batteries. Despite that, they are compact and portable. That makes them the best choice. Despite their long lifespan, lithium batteries eventually die. But Reconditioning is the best way to prolong their life.

  • Lithium-Ion Battery
  • Safety Glasses
  • Safety Gloves
  • USB Cable
  • Crocodile Clips
  • Voltmeter

Below are some of the best methods to follow if you don’t know How To Recondition A Lithium-Ion Battery by yourself. Moreover, while following any method, let us know in the comment section if you get any issues. We are there to help you all the time!

Method 1:

Take A Reading Of The Voltage

This procedure begins with taking a voltage reading using a voltmeter. When Li-ion batteries are overdrawn, they enter a sleep mode, making the battery more energy efficient. Leaving a constantly discharging battery in a device for a long time may result in the battery being unable to recharge anymore.

You can see that the battery is already under 1 volt when you read your voltmeter at 3.7 volts. When this happens, the Li-ion battery cannot be charged. However, it is possible to fix this. A power source or another battery is what you need to jumpstart your battery.

Jumpstart The Battery

If you are replacing the battery with one having the same voltage rating, this method can restore the battery. Simply connect the batteries. Attach the batteries by using the crocodile clips. If you want your circuit to work, make sure both cables are connected to the positive and negative.

After leaving the batteries, keep an eye on them for up to 15 minutes. Make sure that there are no damages. In addition, make sure the batteries are not overheating. The voltage of the battery should then be checked with a voltmeter. With the Li-ion battery now charging normally, you can observe a higher voltage.

Method 2:

The battery can also be frozen as another effective method. It sounds strange, but this works well. To repair the equipment, you must remove the Lithium-Ion battery. Ensure that the area is cleaned clean and free of leakage traces. Seal the pouch with a zipper. Let it freeze for 24 hours. The ziplock bag must not have any moisture inside for the battery to remain dry. Do not use the battery immediately after removing it from the freezer.

The lithium battery needs to be thawed first for the lithium battery to wake up. Allow it to come back to normal temperature after about five to six hours. This doesn’t require you to place it outdoors. Keep it inside. Plugin the charger and fully charge the battery. Your battery will perform better now.

You should always keep safety in mind when using reconditioning methods. Be sure to wear gloves while working. You should never handle the battery with your naked hands, and the battery should not leak. It is best to consult a repair service expert if the situation appears to be risky.

Method 3: Use Another Battery as Power Source

As a power source, you can use another healthy battery. If you are reconditioning an old battery, make sure this new one has the same voltage.

Step 1: By connecting the new and old batteries with crocodile clips, you will create a parallel circuit. The neutral charge should be connected first, followed by the positive charges using jumper leads or spare wires. It should now work.

Step 2: For 5 to 15 minutes, let the batteries sit in the circuit. Do not let the batteries get hot since that will damage them.

Step 3: Make sure the dead battery is reading and break the circuit. A dead battery will have a higher reading than the initial reading. If the battery is functioning properly, it can charge.

Some other ways to Recondition A Lithium-Ion Battery are:

Attempt Full Charge: Your lithium-ion battery can be saved by fully charging it. The following method might be helpful if your battery seems completely dead. Before you go through with it, you should completely drain the battery. Continue to use your battery in your device by turning it on until there is no more power in the battery until it is completely dead. Charge it for at least 48 hours by connecting it to a charger. Weekend plans might need to be made if you want to do this.

Using USB Cable:

As a third option, you can use an old USB cable. During the process, you’ll cut one end of it.

  1. To make sure the black and red wires are exposed, cut the end of the USB cable nearest the device you want to connect. Connect the other end of the Cable to your Computer.
  2. Your dead battery’s positive terminal must be connected to the red wire, while its negative terminal must be connected to the black one. Watch the battery while keeping it in this position for a few minutes.
  3. If you notice a change in the voltage reading of the battery, test it multiple times.
  4. Charge the battery for an additional three hours using the Li-on charger, depending on the model you have.
  5. Use a flashlight or torch to discharge the battery.
  6. Put the battery in the freezer for 24 hours after sealing it in an airtight bag. Keep the bag dry at all times.
  7. It will take between six and eight hours for the battery to warm up back to room temperature once it is taken out of the freezer.
  8. After charging to maximum capacity, check the voltage on the battery. You should have been able to use it.

Can you Recondition A Lithium-Ion Battery?

In many ways, lithium batteries and lithium-ion batteries are the same. This has been the case since long before lithium-ion batteries were invented. The problem is that lithium batteries are difficult to refuel and dangerous to handle. This led to the development of rechargeable batteries.

In addition to their higher capacity, lithium batteries can be used for longer periods of time without needing to be recharged, so they are still in use today. Unlike lithium-ion batteries, which are made of a mix of metals, their anodes are made from pure lithium. This makes them cheaper and easier to manufacture. In contrast to lithium batteries, lithium-ion batteries are degraded after only three years when they are left on the shelf.

Make sure to Keep your Lithium-Ion Battery Healthy

It is important not to allow lithium-ion batteries to get too hot. Heat directly affects the performance of lithium-ion batteries at low temperatures. Leaving the Lithium-Ion battery to discharge by itself isn’t a good idea. If the battery has been discharged, charge it as soon as possible.

Charge the battery often, contrary to popular belief. As they have no memory effects, recharging them even if they aren’t completely discharged is still a good idea. Those batteries last longer with proper maintenance than those that aren’t. It’s important to charge these batteries with their original chargers. The life of the battery depends on the charger.
