Most people are unaware that these seemingly useless batteries can have multiple practical applications in our daily lives. When used wisely, we can turn waste into a “treasure.” Here are some fantastic uses for old batteries that you may find helpful.
1. Eliminate Static Electricity in Dry Seasons
During autumn and winter, dry weather can cause static electricity, especially when putting on or taking off clothes or touching metal objects. Static electricity can be more than just a startling sensation; it can also be painful.
To get rid of static electricity, you can use a battery. A simple trick is to touch the doorknob with the battery before opening the door and touching the metal handle. This reduces the chance of getting shocked when opening the door.
Additionally, you can briefly rub the battery on your clothes before putting them on or taking them off. This method effectively reduces static electricity.
The reason behind this is that batteries have a voltage difference, allowing static electricity to move along the circuit, thus transferring the static electricity from your clothes or metal objects into the battery, effectively eliminating it.
2. Transform it into a Stylus
In our daily lives, we often face inconveniences when we need to operate our mobile phone screens, especially when wearing gloves or having wet hands. Whether it’s rubber gloves for household chores, thick winter gloves, or simply wanting to keep your hands clean, using your phone can become a challenge.
However, there is a simple and effective solution to this problem: using a used battery as a stylus. All you need to do is touch the negative electrode of the battery to your phone, and you will instantly be able to operate the screen as if you were using your finger.
So, the next time you find yourself unable to use your phone with your hands, remember that a used battery can be a handy tool to overcome this issue.
3. Sharpen Dull Scissors
Over time, scissors will inevitably become dull and difficult to use. But don’t worry; you can easily sharpen them with a simple trick using a battery.
Simply cut through the battery with your scissors. This method not only sharpens your scissors but also saves you money. Give it a try and see the difference!
4. Reuse Batteries
When a battery runs out of energy, and you don’t have a spare or can’t buy a new one immediately, you can try a simple trick to reuse the battery. Use a pair of pliers or tweezers to squeeze the battery gently. However, be careful not to use too much force to avoid damaging the battery. After this, you may find that the battery can function again.
This happens because the chemicals inside the battery are not entirely consumed during use. Instead, the chemical reaction inside the battery may slow down or stop for various reasons. When an external force is applied, the chemicals inside the battery are redistributed, stimulating the chemical reaction to continue and release the remaining electricity, allowing you to reuse the battery for a short period.
