It turns out that the old battery is a "treasure", 6 uses you will never think of, and you will never throw it away after reading it!
When it comes to old batteries, I believe everyone is familiar with them, and almost every family will have some old batteries. When dealing with these old batteries, people's first instinct is to throw them in the trash, thinking that the batteries are dead anyway and that keeping them will take up space. But these small batteries are not simple at all, and they have many hidden uses, but many people don't know about them. So what are the uses of old batteries?
1. Remove static electricity.
The most troublesome thing in winter is static electricity, which often occurs when we wear sweaters or other fabrics. So how can you solve these static electricity? Just prepare an old battery, and then rub it back and forth on your clothes, about a minute or so, you can successfully solve the static electricity. Because the battery itself will have a potential difference, static electricity can flow down the circuit, transferring the static electricity on the clothing directly to the inside of the battery.
2. Control the mobile phone.
Since most mobile phones nowadays are touchscreen phones, once you put on gloves, it is not so easy to control. Is there a way to put on gloves without delaying the control of the phone? In fact, there is also a way, we only need to prepare a waste battery, and then aim the tip of the battery at the phone screen. Because most used batteries still have some remaining power in them, these conductive metals are enough to increase the sensitivity of the touchscreen.
3. Easy to carry the bag.
When we go out shopping, if the contents of our hands are too heavy, we will feel a special feeling of strangulation. After a long time, it will also make a deep red mark on the hand. At this time, we can take out an old battery and jam the old battery at both ends of the plastic bag, so that the pressure of the plastic bag will be shared, which is equivalent to widening the handle of the plastic bag. It's all the same thing, but it's easier to bring it up.
4. Fix the garbage bag.
I don't know if you have noticed that in the process of putting garbage bags, garbage bags often slip off the edge of the garbage can, which will cause garbage to be thrown everywhere, which will not only increase the difficulty of cleaning, but also lead to the spread of bacteria. How do you solve this problem? Actually, the method is very simple. We just need to jam the old battery on the edge of the outer wall of the trash can, and then put the trash bag directly on the battery.
5. Secondary use.
Many people think that the old battery that has been replaced is useless, but this is not the case. Many old batteries are not dead, but they are relatively low. We can put two batteries together, squeeze them hard, or bite them with our teeth. After squeezing, it will be found that the battery can be used again.
6. Sharpen scissors
There will be scissors in almost every family, because with scissors, we will also become especially convenient when cutting things. However, many people find that scissors become particularly strenuous after using them for a period of time. In fact, we only need to take out some old batteries that are not used, and use scissors to cut more waste batteries, so that the scissors will become particularly sharp. If you haven't tried it yet, I recommend you give it a try.
