Convert AA Batteries to C Batteries Using Thin Cardboard Strips
If you need C batteries for one of your tools, a small cardboard or thick paper can turn some AA batteries instantly.
Sometimes the tools or toys you own require larger batteries than the much more common AA batteries, which you probably keep in a drawer somewhere. YouTuber kipkay recommends a simple conversion if your flashlight needs some juice and you’re stranded. AA batteries have the same height and voltage as C batteries, so the only thing stopping them from playing well is their size. Cut off strips of thin cardboard or thick paper and wrap them with AA to increase their circumference and you’re done. Of course, the downside here is that AA batteries won’t last as long as C batteries. However, it’s better than nothing, and sometimes you just have to work with what you have .
