In 2 Seconds, This Technique Will Tell You If Your AA Battery Still Works

Batteries can make your life easier, but also can make your life miserable at the same time when you are in shortage of them. On top of that, it can be a hassle trying to figure out which type of battery goes into which device you are in need of energizing.
We all use them, but not many people know just how much they can do with ordinary batteries. Check out some amazing battery tricks in the list below!
Capacity Test - Don't you hate it when you can't tell if your battery is fully charged or not? It can be frustrating, especially when you switch out your batteries, only to find the new ones are duds too. By dropping your battery on a hard surface, you can tell whether it has a full charge or not. If your battery is empty, it will bounce, but if it has a full charge, it won't bounce at all.
Conversion - If you realized your device takes AA batteries, and all you have lying around are the AAA kind, there's no need to go to the store. You can actually turn your AAA battery into a AA. All you have to do, is take a piece of aluminum foil to cushion your battery to make it fill the space better. This extension of the AAA battery will trick the device into thinking you really have a AA in place.
Drawing Tool - With all of the touch screen phones out there now, sometimes you may get tired of using your fingers to scroll up and down. Instead, take the end of a standard AA or AAA battery and use it as your new scroller or drawing tool for all of your touch screen devices.
Fire Starter - In need of a flame to light a campfire? No problem. Take a battery and stand it with the positive end facing upwards. Cut a tiny strip of a Doublemint gum wrapper, placing one end of the wrapper strip on either side of the battery. You now have several seconds of a flame before the wrapper burns itself out.
Hand Warmer - If you are wanting to save on your electric bill, instead of turning on the heater, use a battery for a quick hand warmer fix. Simply roll the battery in aluminum foil, completely covering the it like a tootsie roll. The temperature will soon rise to 104 degrees Fahrenheit. If it is too hot, simply add another layer of foil to cool it down.
Magnet - To make a quick magnet to clean up tedious messes, all you need is a battery, a screw, and copper wire. Wrap the copper wire around the screw about 20 times, leaving a wire slightly sticking out at the top and the bottom of the screw. Take the wire that is sticking out and hold onto the ends of the battery, to where the wire screw is hanging down like a swing. Swing over what you are trying to magnetize, and watch it work like a charm.
