Often we miss good shots in the forest or the sea, we may be late or stumble in the dark, because a simple battery from a camera, a watch or a flashlight suddenly went out of order. When exactly the charge will be spent, it is difficult to say, except that it is not a Duracell model with an indicator. But do not despair! Thanks to several tips, you can avoid unpredictable situations and make imaginary photographs from a digital camera, find out the exact time, light the road, etc. In this article we will show you how to charge batteries at home without a charger, which will greatly facilitate life in unpredictable situations.
Know that to charge alkaline batteries you can use a special charger that can quickly restore a discharged object. But each charge session will shorten its life by approximately 1/3.In addition, it is possible to leak.
Please note! At home, you can charge: alkaline( alkaline) finger batteries. It is impossible: saline. Do not rule out the possibility of leakage or even explosion!
Charging can be performed in various ways. Therefore, do not throw out the item as soon as it has ceased to serve. A few recommendations - and he again in the ranks. The first method, using which you can independently charge your finger batteries without a charger. We connect the power supply to the network. Then, using the wires for the connection, we connect the used battery to the unit. Do not forget about the polarity: plus is connected to the plus, and the minus is connected to the negative. It's quite easy to find where the "- \ +" is empty. They are marked on the case. 
Connect the battery to the power source, wait until it heats up to fifty degrees, and turn off the power. Further, we expect several minutes to cool the heated object. Otherwise, it may explode. Then, while AA is still warm, it needs to be charged in a different way. It consists in the following: connect the power supply unit to electricity and disconnect. It takes about 120 seconds to do this. Next, we place the object for charging in the "freezer" for 10 minutes, then we get and expect 2-3 minutes, that it would warm up. Everything, the charge is restored directly at home without a charger! You can safely use it for the same computer mouse.
Main rules:
- Charge is not feasible if you place + and - otherwise. On the contrary, the battery will be discharged even faster.
- It is possible to charge the object at home 1-2 times.
- By the method described above, you can charge only simple finger alkaline batteries.
- Charge is possible in any temperature environment.
Another method of charging is a method of ordinary heating. But it is fraught with consequences( explosion).In this way, you can restore, again, small alkaline batteries at home. You can also charge them in a simpler way - to place discharged objects in hot water, but not more than for 20 seconds, otherwise sad results are possible. Another uncomplicated way is to flatten or reduce the volume of the element with your own hands. So you can charge various finger batteries. There is an example when a person after the discharge of a lithium-ion battery simply took out and stamped it, after which the charge indicators showed one hundred percent.
To restore the charge without the charger, you can also do this: make 2 holes with a stylus about each carbon rod three by four deep from the height of the element itself. In them, pour liquid, and clog them, covering them with resin or plasticine. You can pour not just liquid, but an eight to ten percent solution of hydrochloric acid or double vinegar. Fill the solution several times for sufficient saturation. This method allows you to charge up to seventy to eighty percent of the initial capacity.
Another way to charge the product: open the cover of the element with a knife. If the cylinder of zinc, the core of the object and the coal powder are unharmed, then immerse the object in a solution of salt. The ratio of it is as follows: 2 tablespoons of table salt per several glasses of liquid. Next, boil the solution together with the element for about ten to fifteen minutes. Then we return to the place the gaskets responsible for sealing, and cover with wax or plasticine.
In this article we have suggested to you how to properly charge batteries at home without a charger. The proposed advice applies only to finger batteries, since they, in contrast to the small, flat( tablets) used for lasers, are most often used in everyday life. Now you can charge the necessary elements even if there is no electricity!
