Have you ever looked for a working battery for a remote control or a toy, only to find that all the ones you have are dead? Before you throw them away, there is a clever trick to give them a new lease of life. And the good news? You probably already have everything you need at home!
Why do batteries drain so quickly?
Batteries work by a chemical reaction that generates electricity. Over time, this reaction slows down , and the battery seems unusable . However, in many cases, there is still energy to be harnessed , but the connection between the internal elements has weakened . Rather than replacing them immediately , a simple saline solution can sometimes revive their potential .
The Salt and Hot Water Trick: How Does It Work?
Salt water is an excellent conductor of electricity . When a battery is immersed in this solution , electrons can flow again, temporarily restoring a useful charge to the battery .
What you need:
- 1 tablespoon of salt (fine or coarse, it doesn’t matter)
- 150 ml of hot water
- A heat-resistant container
- A spoon for stirring
- Paper towels
- Dead batteries
