Of course, a cell phone is convenience and comfort, without which it is very difficult to imagine life now. For this reason, if we are left without a phone, then we feel discomfort. What if your cell phone is out of power and you can't charge it in the usual way?
The easiest way to recharge a battery is to recharge via the usb connector by connecting to a computer. But this possibility is not always available. How to be in this case?
For the convenience of users, portable devices powered by AA batteries have appeared on the market today, or chargers, which are similar to cellular chargers, are charged from the network, accumulating energy.
But what if you are far from civilization and do not have the opportunity to charge your mobile phone, while it is vital for you to make a phone call?
Consider popular ways to recharge a battery.
We use copper wire, which we wrap around the metal plates. We stick the wire into the ground and connect the battery to the wires. The wire should be watered with electrolyte or ordinary salt water.
The next method is to heat up the battery. Of course, such a charge will not last long, but it will be possible to make a small call. We rub the rechargeable battery on any dense material, cloth. After heating the shell, this heat is converted into charge.
This method requires lemons. We insert the nail into the pulp of the fruit and connect it using copper wire from the batteries.
You can use batteries from any equipment (radio, flashlight). Using copper wire, we connect the cell battery to the batteries.
Of course, you can resort to using any method, but you should be careful and take care in advance about the integrity of the battery pack, not allowing it to be completely discharged.
