Have you ever had a depleted battery in your camera when you needed it most? But worse is if your battery dies in an emergency situation. And you can't always carry a charger with you. For those who enjoy (or need) to improvise, the following recommendations will come in handy.
Step
Method 1 of 2: Using the Battery to Charge
Step 1. Remove the battery from the appliance
You need access to battery connection points. Keep in mind that batteries are not meant to be accessed on some phone models, so know what you can do with the model you have. On most (but not all) Android and Windows phones, the back can be removed with a little pressure at the right point. But don't do this with most Apple products.
Step 2. Get some AA, AAA, or 9 volt batteries ready
Unlike power that comes from a wall socket (alternating current), power that comes from a regular battery isn't much different from the battery you use in your phone or camera. battery.
- Maybe you are confused by people's advice to use one battery to charge another. Maybe you're hoping for a magic trick that will allow you to charge yourself without having to find another power source. In fact, that's not very possible. One of the basic laws of physics (the law of conservation of energy/conservation of mass) explains that you can't get something out of nothing. Just accept it.
- It is recommended that you charge it instead of trying to power the electronics by connecting them directly to an alternative battery. Improper amperage and volts can damage complex circuits, so it's definitely not worth the risk.
Step 3. Identify the positive and negative connectors on each battery
On AA batteries and other ordinary batteries these links are clearly marked. In most cell phone batteries, the positive connector is closest to the edge of the battery, while the negative connector is usually at the furthest from the edge (there may be two or three connectors, but one or two middle connecting points are used for temperature regulation and other functions).
Step 4. Adjust the voltage of the battery to be charged with the voltage of another battery (AA, AAA, or battery with sufficient power)
Normally, the current cell phone battery requires an overvoltage of 3.7 V DC. So, several AA or AAA batteries, or one 9 V battery should be sufficient to charge the battery. Keep in mind that everyday AA or AAA batteries have a voltage of 1.5 V. So, to get more than 3.7 V, you need 3 AA or AAA batteries connected in series. Neither AA nor AAA 1.5 V + 1.5 V + 1.5 V = 4.5 V batteries should be more than enough to charge.
Step 5. Take two pieces of metal wire
Ideally, this wire is covered with plastic insulation except for the two exposed ends.
Step 6. Glue it with tape or clamp the wire on the battery that will charge the battery that needs charging
These wires can get hot (though they shouldn't if you do it right). It will also take some time to transfer the power. You won't want to hold onto it the whole process.
If you are using AA and AAA batteries, you may need to connect them in series before attaching them to batteries that require charging. This means using the wire to connect the negative side of all small batteries to the negative side of the battery that needs to be charged, and so to the positive side
Step 7. After some time, your battery should be charged
Keep in mind that the battery may not be fully charged, but you should have enough power to use the tools you need.
Method 2 of 2: Using the Rubbing Trick
Step 1. Remove the battery from the electronic device
Hold it with both your hands.
Step 2. Rub the battery vigorously with both hands to create enough friction and heat
Continue doing this for 30 seconds to a few minutes.
- Note: Your battery is not completely charged. Some internet commentators suspect that rubbing the battery actually provides additional charging, presumably from the accumulated static electricity. This interpretation is completely incorrect.
- Lithium ion cells, like actual batteries, release electrical power as a result of a chemical reaction. As predicted in the Arrhenius equation, this reaction becomes stronger as the temperature increases. In essence, you increase the conductivity of the battery by increasing its temperature.
Step 3. Insert the battery back into the electronic device
You may only have a few moments of extra battery life, so make the most of it.
Warning
- Make sure you have turned off the electronics before removing the battery or you may accidentally change the appliance settings.
- You should only try to charge a rechargeable one. Do not attempt to do so with alkaline batteries or others intended for limited use only.
- Do not overcharge. Lithium batteries can explode if they are overcharged.
