The conventional methods of charging batteries at home
Charge batteries at home, in the following way. With batteries you need to remove the wrapper, and then in the body done a few holes. This can be done with an awl or a Gypsy with a needle. Prepared for charging the batteries fall in a pot of well-salted water. Then the pot is put on the gas, and the batteries boil for a short time. Then you need the batteries removed from the water, dry, wrap well with electrical tape. So, as a result of the process of the battery charged and ready for a new job.
It is also possible to charge ordinary batteries with an awl. So, awl is required to make two holes all elements of the supply near the graphite rod. The depth of the puncture should take about ¾ of the height of the batteries. In the hole you need to drop either water or a 10% solution of hydrochloric acid, either double vinegar. After the liquid dripped to the top, the holes are sealed well with a slice of rye bread or clay. Ordinary batteries charged so that can serve for some time.
The methods of charging ordinary batteries by using special devices
Today there is a special device (device), for example, Battery Wizard, which can fully charge ordinary batteries up to 10 times or more. Many people consider it quite a bargain, which will allow in the future to save a decent amount of money.
You can charge regular batteries using a special charger. Batteries should be placed in the device and put on charge. As soon as the batteries are a bit warmer, they must be immediately removed. If the battery overheats, becomes hot, the charger may come in unsuitability, fire, or the battery to explode. Try, warmed up the batteries or not, just by hand.
Of course, to resort to the assistant drugs and Amateur experiments possible, but very carefully and very rarely, if the situation requires it. It is best to use special devices to charge conventional batteries or buy new batteries.
