Have you ever looked for a functional battery for a remote control or a toy, to finally find that all the ones you have are unloaded? Before throwing them away, be aware that there is an ingenious trick to give them a boost. And the good news? Surely you already have everything you need at home.
Why do the batteries discharge so fast?
The batteries work with a chemical reaction that generates electricity. Over time, this reaction slows down, and the battery seems unusable. Yet, in many cases, there is still room for energy, but the connection between the internal elements has weakened. Rather than replacing them immediately, a simple saline solution can sometimes rekindle their potential.
The cleverness of salt and hot water: how does it work?
Salt water is an excellent conductor of electricity. When a battery is immersed in this solution, the electrons can again circulate, temporarily restoring a payload to the battery.
What you need:
1 tablespoon of salt (end or large, whatever)
150 ml hot water
A heat-resistant container
A spoon to stir
Paper towels
Discharged batteries
Instructions for use
Prepare the saline solution
Heat 150 ml of water, then add a tablespoon of salt. Mix until completely dissolved.
Soak the batteries
Dip the discharged batteries into the solution. Swirl slightly to ensure proper distribution of the salt over the entire surface.
Leave it to act
Wait 15 to 20 minutes to ensure that the solution works and reactivates the internal components of the battery.
Dry carefully
Take the batteries out and wipe them thoroughly with absorbent paper. Any trace of moisture should be removed to prevent oxidation.
Test the batteries
Put them back in your device and check if they’re working again.
Does this method work on all batteries?
