Like most households, you probably have a lot of used batteries lying around your home.
We use batteries for TV remote controls, wall clocks, and even for children’s toys such as cars, robots, dolls, and walkie-talkies. All too often, the struggle is to determine which of your old batteries are still good or no. Sometimes it can be time-consuming to swap batteries one by one just to get your, say, remote control working again.
Of course, you can always use a digital multimeter to help you determine which batteries still have remaining power but what if you don’t own one?
With this little experiment, you will be able to easily determine which of your alkaline batteries are still useful and which ones are already dead. What’s great about this hack is that it will only take you about two seconds to do that. So whether you have a meter or not, go grab some batteries and try this hack.
Watch the video here:
As you have just seen, it is indeed possible to find out if an alkaline battery is still good or not just by dropping it on a hard surface. Spent batteries will usually bounce while good ones will land with a thud and will often stand. This works for any type of alkaline battery such as AA, AAA, C, and D.
Although no explanations were given behind the phenomenon, using this simple method will help you avoid the necessity to buy new packs of alkaline batteries all the time. You will be able to save money and make the most of your batteries. Also, you can get rid of the bad ones and have fewer batteries in your home.
