There are many types of electronic devices in every household, from TV remotes and electronic toys to children's learning machines. What they all have in common is that they rely on batteries to operate. However, when the batteries run out, we often discard them, which is actually quite wasteful.

In reality, we don’t need to rush to throw batteries away once they are drained. First, you can try removing the battery from the device. If you have pliers on hand, gently hold the battery with them; if not, a disposable chopstick can also work. By following this method and squeezing the battery five or six times within about ten seconds, you’ll notice that the electrical energy inside the battery has been partially restored. At this point, reinstall the battery into the remote control, and it will regain power to continue functioning normally.

Often, when a toy’s battery dies, it can still be used in a remote control. Although the battery may no longer supply enough power to run a high-energy device, it can still provide sufficient energy for low-power devices like a remote control, allowing for extended use before it is completely exhausted.

Of course, batteries have a limited lifespan, and when they are drained again, we still shouldn’t immediately throw them away. Used batteries are far from useless; in fact, they have a variety of practical applications, especially during the fall and winter months.

1. Used batteries can be turned into a stylus for touch screens. During winter, it’s often difficult to operate smartphones smoothly while wearing gloves. By using the negative end of a used battery to lightly swipe across the screen, you can easily perform tasks such as flipping pages, typing, or browsing information. This provides a quick, cost-free solution for touch screen usage in cold weather.

2. Used batteries can help eliminate static electricity. In the fall and winter, static cling becomes a common annoyance. Simply rubbing the positive end of a used battery gently over your clothes a few times can neutralize static electricity, making your clothing more comfortable and preventing shocks when touching metal objects.
   
   

3. Used batteries can even sharpen dull scissors. When your scissors become blunt, you can cut along the edge a few times using an old battery. The slight abrasion helps restore the sharpness of the blades, making them function almost like new
   
   

4. Additional practical uses of old batteries. Beyond these examples, used batteries can also serve as small weights for DIY projects, temporary electrical contacts for small circuits, or even as simple teaching tools to demonstrate basic electricity concepts to children. These creative applications highlight that even drained batteries can be surprisingly useful.

By exploring these tips, we can fully utilize old batteries and reduce unnecessary waste. At the same time, these methods can save a considerable amount of money in daily household expenses while promoting environmentally friendly practices.
