Check an Alkaline Battery Using the Drop Test

Do you have a stash of alkaline batteries, but aren't sure whether they're still holding a charge for use? Here's a simple way to test their stored charge using a fascinating method: drop them a few inches onto a hard surface, listen to the sound it makes, and check if they land standing up. The explanation of the "why" and "how" below...

According to tech YouTube vlogger Kipkay, a battery with a full or near full charge dropped a few inches will often land upright with a solid "thump" sound, while a drained alkaline will bounce, due to the accumulation of gas produced inside after all the alkaline is used. Give it a try the next time when it's time to replace the remote or wall clock batteries (I did, and it worked just as shown above!).
