How to charge lithium ion battery without charger
If you find yourself without a charger for your lithium-ion battery, don’t panic, as there are other options at your disposal.There are a few ways you can charge a lithium-ion battery without a charger.
Lithium-ion batteries are becoming increasingly popular in a variety of electronic devices, from cell phones to laptop computers.These batteries have a number of advantages over traditional lead-acid or nickel-cadmium batteries, including lighter weight, higher energy density, and no memory effect.
Suppose you are reading this and experiencing a problem with your lithium battery not charging. Lithium batteries rely on electronic devices to function. If your lithium battery has stopped taking charge, it will no longer be capable of powering any devices to which it is currently connected. It is important to recognize that this article can effectively resolve this problem without incurring much expense or risk to personal safety. We will address how you can remedy this problem very simply and straightforwardly.
Can You Charge A Lithium Battery With A Regular Charger?
Yes! If your regular charger (which is a lead-acid charger) has a maximum voltage setting and does not have an automatic equalization mode active, you can use it to charge lithium batteries.
In the end, the most effective method for maximizing the performance and lifespan of any lithium battery is to use a battery charger with a specific lithium charge algorithm.
8 Methods on How to Charge Li-ion Battery Without Charger
Method 1: Use USB Port
This is the most common method to charge a Li-ion battery without a charger. All you need is a USB cable and a computer or power bank.
First, make sure that your computer recognizes the device. Next, connect the USB cable to the laptop and the battery, ensuring that the positive and negative terminals are aligned. Then, wait for the charging icon to appear on the screen.
Connect the USB cable to the power bank and the battery if you’re using a power bank. Then, please turn on the power bank and wait to start charging.
Method 2: Use Car Charger
Another way to charge a Li-ion battery without a charger is to use a car charger. This is especially useful if you’re planning to use your phone while charging. Just plug the car charger into the cigarette lighter and connect the USB cable to both the car charger and your device’s battery.
Method 3: Use Solar Panel Charger
A solar panel charger is ideal for people who often go camping or hiking without power sockets. All you need is a solar panel, which can be bought in an electronics store near you, a USB cord, and, optionally, a battery pack.
First, make sure that your solar panel can charge your battery pack by connecting them with your USB cord. Then attach it to your backpacks when you leave so they will get charged throughout the day. Then, when you feel like using them at night, detach the solar panel and connect it to your device through the USB cord. This step is vital in how to charge li-ion battery without charger.
Method 4: Use AA/AAA Battery Charger
If you don’t have a computer, car charger, or solar panel available, you can use an AA/AAA battery charger. This is not as efficient as the other methods, but it will work pinch.
First, find an AA/AAA battery charger. Connect the positive and negative terminals of the battery to the corresponding ports on the charger. Plugin the charger into an outlet and wait for it to start charging. Once it is done, disconnect the battery from the charger and replace it with your Li-ion battery.
Make sure that you are using a compatible battery charger. For example, some AA/AAA battery chargers are not meant to charge Li-ion batteries.
Method 5: Use Power Strip
This is the last method you can use to charge your device without a charger. If you have a power strip with multiple outlets, you can use this to your advantage.
First, connect the power strip to an outlet. Then, connect your phone or device to one of the outlets on the power strip. Finally, turn on the power strip and wait for your device to start charging.If you’re using a fast charger, make sure it is compatible with your device. Some fast chargers only work with specific devices.
Method 6: Use Bench Supply to Charge Battery
This is a more advanced method and is only recommended for people familiar with electrical engineering.
First, you will need to find a bench supply. This electronic device can supply a high amount of current to your device. Connect the positive and negative terminals of the battery to the corresponding ports on the bench supply. Plugin the bench supply to an outlet and wait for it to start charging. Once it is done, disconnect the battery from the bench supply and replace it with your Li-ion battery.
Make sure that your bench supply is compatible with your device. For example, some bench supplies are not meant to charge Li-ion batteries.
Method 7: Use Dc Electricity to Charge Battery
This is the most advanced method and is only recommended for people familiar with electrical engineering.
First, you will need to find a dc power supply. This electronic device can supply a high amount of current to your device. Connect the positive and negative terminals of the battery to the corresponding ports on the dc power supply. Plugin the dc power supply to an outlet and wait to start charging. Once it is done, disconnect the battery from the dc power supply and replace it with your Li-ion battery.
Make sure that your dc power supply is compatible with your device. For example, some dc power supplies are not meant to charge Li-ion batteries.
Method 8: Use Another Battery to Charge Battery
This is the most advanced method and is only recommended for people familiar with electrical engineering.
First, you will need to find a battery compatible with your device. Then, connect the positive and negative terminals of the battery to the corresponding ports on the charger. Plugin the charger into an outlet and wait for it to start charging. Once it is done, disconnect the battery from the charger and replace it with your Li-ion battery.
Make sure that you are using a compatible battery. Some batteries are not meant to charge Li-ion batteries. These methods will help in how to charge li-ion battery without charger.
Precautions
Make sure the battery is completely drained before charging.
Only use quality batteries and chargers.
Do not leave the battery charging unattended.
Remove the battery from the charger as soon as it is fully charged.
Check the polarity of the battery terminals before charging.
tore batteries in a cool, dry place when not in use.
Dispose of batteries correctly according to local regulations.
Charge Your Lithium-ion Battery from Car Battery
Don’t you have any more options to charge li-ion battery without charger (10-11)? Cool down. You have another handy option as you are driving your car. You can easily charge your battery from your car battery. How? It’s simple. You can charge the battery just connecting it to your car battery which comes with a lead-acid battery. But, charging in such a clever way, you have to use small light bulbs which will regulate the current flow. Now, you may have a question: how many small light bulbs should I use? If your car owns a 13V lead-acid battery and you want to charge a 6V camera battery, you need to use 3 small light bulbs. And you have to arrange or put 3 bulbs in a parallel way to accomplish the charging job. It will allow 0.5 amperes to the battery so that the battery gets charged without any trouble. Then, wait for 10-15 minutes. Your battery will get enough charge for the use.
Charging Lithium Battery From Alternative Battery
You have another easy way of charging a lithium-ion battery without a charger (20-36). To avail this simple way, you have to get 3 AAA batteries to charge your battery effortlessly. At once when you get the batteries, arrange them in a series and then connect all. Since each battery owns 1.5V, the three will produce 4.5V together. A standard cell phone battery needs 3.7V to get charged fully. But the three AAA batteries will prove 4.5V together. So, they will charge your battery without any hassle. But, one thing you should keep in mind.Never go for using too much voltage to charge the battery. It may hurt your battery cell.
Can I charge Li ion battery with phone charger?
Yes, you can, assuming you have a proper 18650 charger. The circuitry required to charge a lithium ion battery is built into 18650 charger. So it will safely charge your phone battery.
Can you charge a lithium battery with a regular lead acid charger?
You can use a lead acid charger on a lithium battery if you want, HOWEVER, you must NOT use a lead-acid charger if it has an automatic “equalisation mode” which cannot be permanently turned off.
