An Alternative to Testing Batteries with Your Tongue

Have you every been looking for a 9V battery and you find random batteries lying around in a drawer somewhere. Most of the time, they’re right next to the package of brand new package of 9V batteries. For some reason, you feel inclined to use the loose batteries first before opening up the new package…just to see if they’re still good.

So before taking the time to add them to the toy or device, you use the old-school tongue testing method. If it gives you a little shock, the battery has some charge left in it.

We’ve all done the tongue test before, unless you’re a big ole chicken, they you probably asked one of your kids to do the tongue test for you.

So here are a few alternatives to testing the 9V batteries with your tongue, and testing 1.5V batteries as well.

Methods for Testing Your Batteries

First Method

Apparently, when the alkaline in your 1.5V batteries, such as a AA battery, is all used up, it creates gas inside your battery. So what you can do, if you find a stack full of batteries, is give them the drop test. You don’t have to drop them but a few inches from the table surface, standing with the positive end up. A battery that is fully charged will make a solid thump and most like stay standing up. Batteries which are all used up will bounce several times and fall over, making a muffled sound.

Second Method
