Many people know that portable energy sources are rechargeable and ordinary. It is believed that if the batteries are knocked on the wall or slightly changed in shape, then their service life can be extended by several hours. And this is absolutely true. However, there are other proven and original ways to charge the battery with your own hands at home.

How to know if you can recharge
The battery differs from an ordinary battery with a capacity of mAh. Often the manufacturer makes this inscription in large letters. The higher this indicator, the longer the battery will work.
If during the purchase you saw the inscription "do not recharge", then the item not rechargeable. Another difference is cost. Battery devices cost much more than conventional energy cells. Moreover, the cost is formed from the cycles of recharging and power.
It is noteworthy that craftsmen have learned to charge ordinary devices as well. To do this, they came up with a lot of ways.
Home charging methods
You should immediately pay attention to the fact that you can independently recharge only alkaline (alkaline) cells. Saline is not suitable for this. In addition, recharging them can be dangerous and result in to very undesirable consequences: explosion, contact of electrolyte in the eyes, etc.
Charging can be done in different ways. Therefore, there is no need to throw away the device immediately after it has become unusable.

One of the methods involves trivial heating. However, this procedure is fraught with an explosion. Safety can be improved by placing discharged devices in hot water for no more than 20 seconds. - Another charging option is to place the cells in a pot of salted water and boil for a few minutes. After that, the element is taken out of the water, wrapped with electrical tape and inserted into the consumer device.
- You can also change the volume with your own hands and flatten the element. There was a case when a person simply trampled on a discharged "alkaline", after which it became charged.
Use of special devices
There are many special chargers on the market today, such as the Battery Wizard. With the help of such a device, you can charge ordinary finger devices several times. Consumers speak of this device as a profitable and economical purchase.
For recharging, the batteries are placed inside a special design, which can have different shapes: square, rectangular, round, etc.
Then the device is connected to a 220 V. After the elements are slightly warm, they need to pull out immediately. If overheating occurs, then this will lead to sad consequences.
Better buy special rechargeable batteries and a charger included. Also pay attention to the manufacturer.
Danger of charging batteries
A large number of companies produce electrochemical cells. You can buy them at any electronic goods and household equipment store. The AA batteries contain caustic alkali. In a confined space, with the passage of electric current, the device can easily explode.
If the battery easily survives the charge / discharge cycle, then its capacity will significantly decrease with subsequent recharges. In addition, electrolyte often starts to leak, which can cause damage to the device installed in the battery.
Is it possible to extend the service life
Ordinary salt-type batteries do not function very well in freezing temperatures and heat. Therefore, it is better not to use them in such weather conditions. The electrolyte inside is converted to gas or freezes, which adversely affects its conductivity.
A discharged battery will work a little longer if its case lightly crush with pliers. But this must be done as carefully as possible in order to prevent damage.
Reagents often clump into small lumps that prevent the reaction from proceeding smoothly. inside the battery. In order to facilitate the process, you can tap the finger-type battery on some solid surface. This will add about 6-7 percent power to the element.
You should also pay attention to the fact that alkaline devices tend to self-discharge. Therefore, when buying, you should take into account the date of manufacture. Old elements will quickly deteriorate.
To achieve maximum battery life, do not install different types in one device. The same goes for installing new elements to old ones. It is best to always have an extra kit in stock. When one has lost its charge, it can be quickly and easily replaced. In this case, you will not need to think about whether the batteries can be charged.
