Batteries are used in a wide variety of household equipment (remote controls, clocks, radio tape recorders, etc.) Over time, they must be replaced. Elements that are still suitable for work are often thrown away, since the methods of "revitalizing" them are not widespread enough.
Necessary
- - awl or sharp nail;
- - syringe;
- - distilled water;
- - 9% table vinegar;
- - 10% hydrochloric acid solution;
- - plasticine or resin;
- - a small hammer;
- - hot water;
- - battery charger.
Instructions
Step 1
The process of restoring the working capacity of a battery is called regeneration. Practice shows that not every element is suitable for recovery, but only one whose capacity and voltage have not dropped below a certain value (for a 1.5 V finger battery, this value will be 0.7-0.8 V).
Step 2
Take into account the fact that batteries that operate at high load currents (flashlights, children's toys, portable radio tape recorders, etc.) are most successful in recovering; much worse - elements operating at low currents (clocks, portable radio, cameras, etc.)
Step 3
If the finger battery has been stored for a long time and has dried out, make two holes with an awl or a thin nail along the central rod in the middle between it and the edges of the battery. The punctures should be made to a depth of approximately ¾ of the cell height.
Step 4
Inject a few drops of water (preferably distilled) into one of the holes with a medical syringe. The displaced air will exit through the second hole at this time. As soon as water appears in the second hole, remove the syringe. After "filling" the battery, cover the holes with plasticine or hot resin.
Step 5
Another, more reliable option for filling a battery is not water, but a 10% hydrochloric acid solution or a double dose of vinegar.
Step 6
You can also revive the battery by immersing it in hot water for about 10 minutes.
Step 7
Mechanical stress can also extend the life of the battery by 2-3 days. Try to gently tap the body of the elements with a small hammer.
Step 8
There are charger options for different types of batteries. Diagrams of such devices can be found on the Internet.
