It is that time of the year again, when people buy and give millions of little gadgets and toys that all run on the popular AA batteries. Here is one for those of you who would like to try making one of these small energy storage devices, using materials that can easily be bought online.
Before moving on to giving you the list of what you would need to execute the task successfully, I would like to give you some points to remember. Firstly, do keep in mind that making an AA battery is far from easy, and not entirely safe. Please do read all instructions that come with the products that you will buy of the internet. Secondly, the market is flooded with numerous brands of the tiny storage devices that come at a wide range of prices and considering the dangers associated with the materials, it might be safer and wiser to just buy a ready-made one.
However, it is very important to note that we tend to appreciate a lot more the things that we make ourselves, rather than the off the shelf products, simply because we have put effort into making something. And considering how careless many people are, especially when they dispose of used batteries, it might not be all that bad to give this tutorial a try, just to know what goes in the devices and how hard it is to make one.
Let’s have a look at what materials are needed. One 5mL plastic syringe, one zinc sheet, pencil lead and the following chemicals: potassium hydroxide, manganese dioxide, and carbon powder. Having all this, you should be ready to proceed with bringing it all together. Here is a complete video tutorial of how to make the AA battery, courtesy of YouTube user NurdRage.
Now, regardless of whether you decided to buy a battery or you followed strictly the tutorial, here are some tips for usage and things to keep in mind.
Always use the same type (and brand) of batteries in you gadgets to prevent leakage- battery fluids can cause serious damage, especially if they get into contact with your eyes. Once the battery is done, dispose of it fast, or keep it away from children. Do not carry batteries along with metal objects to prevent short-circuit. If the battery is too hot, smelly or changes colour- do not use it. Do not try to recharge non-rechargeable batteries, because this might cause explosions. Do not leave batteries in devices, which will not be used for some months to come. And remember- Recycle, Recycle, Recycle!
