This salt-based trick could be able to revitalize your old batteries and prolong their lifespan if you’re sick of having to buy new ones all the time. Batteries that have lost their charge can be temporarily used with this approach, albeit it won’t restore them to their original condition.
Ingredients:
- Old Batteries: Non-rechargeable batteries of the AA, AAA, or comparable kind (alkaline batteries work best).
- Salt: 1-2 tablespoons of table salt.
- Warm Water: 1 cup.
- A Small Bowl or Container: For the saltwater solution.
- Towel or Cloth: To dry the batteries.
Instructions:
Get the saltwater solution ready:
- Pour 1 cup of warm water into a small basin.
- Stir in 1-2 tablespoons of salt until it dissolves completely.
Soak the Batteries:
- Using a cloth, clean the battery terminals of any corrosion.
- For 30 to 60 seconds, submerge the batteries in the saltwater solution.
- Avoid complete submersion by making sure the battery only comes into contact with the solution at the base.
Remove and Dry the Batteries:
- Remove the batteries from the solution and use a towel or cloth to completely dry them.
- To avoid short circuits, make sure there is no moisture left.
Check the batteries:
- To see if the batteries have recovered some of their charge, put them into a low-energy gadget (such as a clock or remote control).
Conclusion
An ingenious method for temporarily revitalizing outdated alkaline batteries is the saltwater technique. Although it’s not a long-term fix, it can save you money and cut down on waste. You might be shocked to discover how much life your batteries still have when you try it the next time they run out of power! 🔋✨
