How to charge old batteries
With this simple method, you can reuse your old batteries using only salt and water, saving money and reducing environmental impact. While this process is temporary, it’s a great quick fix to give a second life to seemingly useless batteries:
Materials Needed
Old batteries (AA, AAA, etc.).
Common salt.
Warm water.
Small container or glass.
Dry towel or cloth.
Gloves (optional, for added safety).
Procedure
1. Prepare the salt solution:
Fill a small bowl with warm water.
Add a good amount of common salt to the water and stir until completely dissolved.
2. Prepare the batteries:
Take the old batteries you want to reuse. Make sure they are not dented or leaking obviously.
Wipe surfaces with a dry cloth to remove any dirt residue.
3. Submerge the batteries:
Place the batteries in the saline solution for a few minutes. The salt will help revitalize the electrochemical process inside the batteries, giving them back some of their charge.
