Losing battery chargers can be a real hassle. Forgetting them someplace else or maybe they just stop working suddenly is not fun either. Now, you are stuck with a dead rechargeable battery with no hope of finding a charger soon. Let’s show you how to charge rechargeable batteries without charger.
So, how do you go about it? Stay with us while we suggest varying helpful tips.
There are several creative ways to go about charging your rechargeable battery without using a charger, from using USB cables to a car battery, and down to using something as inconceivable as lemon juice. Intrigued? Read on.
Use A USB Cable
This is the simplest and most obvious solution to charging a rechargeable battery when you don’t have a charger option. The Universal Serial Bus (USB) is a convenient way to power up your device. Prior to now, these cables were used to charge cell phones only. However, this has changed since several electronic devices come with ports that allow them to be charged with USB cables.
Simply plug in the USB cable jack into a device that allows you to charge using one. Now, attach the other and smaller end on the cable into the device that needs to be charged. The popular options for this type of charging are laptops and power banks.
In as much your laptop is fully charged, you can use it to power up another device. For optimal use, you can use the sleep and charge option on your laptop. This ensures that the laptop’s battery isn’t drained quickly while using it to charge other devices.
By Using Another Battery
So, your device’s rechargeable battery is down, let’s say it’s the Lithium ion battery in your smartphone. Well, you can simply make use of one battery to charge the other.
Start by removing the battery that needs to be charged. Since you are not using an actual charger, reaching the connectors is paramount. If you are using a Windows or an Android smartphone, then you are in luck. Access to the battery in these models is quite easy once you remove the phone’s back cover. However, if you notice that the battery is built-in, ensure to leave the battery that way until you get a battery charger.
Now, go dig out your regular batteries. That is, double A (AA batteries) and triple-A (AAA) batteries used in most household devices like flashlights, game consoles, remote controls, etc. In case you are wondering why you need them, here is why. You can’t charge your phone without an electric source. Since you don’t have the means to an appropriate one, then you have to find an alternative source of energy.
Locate the negative and positive terminals or connectors on the batteries. These areas are usually marked out on regular AA or AAA batteries. To identify these points on your phone’s battery, just look at the terminals on the battery. The one in the middle is not an option (this monitors the battery’s temperature). This leaves you with a connector on the outer edge close to the edge and one far from it. The former is positive and the latter is the negative connector.
Ensure that the cell voltage power on the set of double-A or the triple-A batteries you intended to use have enough direct current. This determines if they would be able to charge the battery. You might want to invest in more that one battery for this. After this, connect these batteries together in series.
Get two plastic insulated metal wire pieces. Expose the ends of each and connect them to the batteries. Now, make sure one end of the wire is connected to the negative connector of the AA batteries, attach the other end to the negative connecting point of the battery you want to charge. Take the second wire and connect its ends on the positive connectors of the batteries.
Now, leave it to charge. It is important to point out that your battery will, most likely, not be fully charged. However, you will have enough battery power to work with until you have an appropriate charger.
Use Lemon Juice
This is probably the most unorthodox way of charging your rechargeable batteries without a charger.
So, you have a pair of rechargeable AAA batteries that need to be charged and you are without a charger, this is a great hack for you. Lemons are said to have acidic contents that are capable of triggering and causing a flow of the electrons in the battery. This flow recharges the battery.
Now, how do you go about this? Gather the lemons you have at home. Make sure you gather enough since you will be needing a lot of its juice. The more juice, the better. Cut the lemons and squeeze out the juice into a bowl. After this, put the rechargeable AAA batteries in the bowl. Make sure the batteries are submerged. Leave them inside for 1 or 2 hours before removing them.
You should know that your batteries might not be fully charged, however, there will be a 70% to 85% power capacity restoration. And that is more than enough if you ask us. Please note, don’t try this with the Lithium-ion batteries in your cell phones. There is nothing that supports it and you should always keep your phone batteries away from moisture.
Rub The Battery
You can use this method for lithium-ion batteries in smartphones. This does not provide a lasting effect. However, you can get a few minutes to put a call through for help if you are stranded somewhere.
To do this, remove the battery and place it on your hand. Now, generate friction by rubbing the battery between your hands. Do this continuously for 60 seconds and more. This process does not recharge your battery, however, the increased temperature due to friction improves the battery’s conductivity. As mentioned above, you will only get a few minutes with the battery.
Recharging A Car Battery Without Charger
A car battery is also a rechargeable battery, hence, the honorable mention. What do you do with a dead car battery when you are without a car battery charger insight?
- The first thing to do is to ensure that you always have an emergency tool kit in your car, in case of necessity. This kit should contain tools like jumper cables, screwdrivers, flashlights and other essentials tools you can think of. Also, make sure you have a fully charged phone to contact someone that can bring a car for you to jumpstart your car battery with.
- Bring out your jumper cables. They often have two metal clamps on their ends. These clamps are encased in black and red plastic insulations that helps you to identify the negative and positive terminals.
- Make sure the ignition is off and ensure that there won’t be any sudden movement from the car.
- Now, open the car’s bonnet and connect the jumper cables. The ends of black clamps on the jumper cables should be connected to the negative terminals of the dead car battery and the good car battery, respectively.
- The same process is repeated with the red clamps on the jumper cables. Each end of the clamp is placed on the positive terminals of the good and dead car batteries, respectively.
- Now, the car with the good battery is started and allowed to run for a while. This process allows the dead battery to charge. After two to three minutes, try to start the car. It will definitely start. If it does not, simply allow the car to draw more charge before restarting it. Once the car is running effectively, remove the jumper cables.
You can easily charge your rechargeable batteries without a charger. The only thing needed is the willingness to try out varying life hacks. This is not a suggestion to try every do it yourself hacks you come across. However, there will always be one that will solve your battery-related problems.
In addition, to prevent finding yourself in this situation too often, you should try a few maintenance tips that will help your device hold a charge for longer. This can be done by buying the appropriate battery for your device, charging the batteries at the right time, and removing them from the device if you won’t be using them for a while.
This is also a good time to advise against putting your batteries in a fridge to charge it. This is a great misconception that has managed to circulate widely. While this may have proven to be useful in helping batteries hold their charge for longer, it can not recharge a dying or dead battery. This is because the battery is not connected to a power source, not even to an alternative energy source.
