TwitterOkay, so you have two batteries (alkaline) around you and you are confused which one is charged and which one is dead. Fortunately, if you have a voltmeter around you then you can easily test it. Even if you have a remote or a clock, you can use those batteries and check it. But, lets consider you don’t have them right now, so here is an easy way to figure it out. Trust me, it’s very easy, I almost became a scientist.
Test If A Battery Is Dead Or Not
When you drop a battery vertically from a short distance onto a hard surface:
Battery (Charged): It will make a solid thump sound and will most probably remain standing.
Battery (Dead): It makes a muffled sound, bounces repeatedly, and then topples over.
Seems like when an alkaline battery becomes dead, the chemicals inside them become a gas. This will affect the composition of the battery, thus you can easily test if a battery is dead or not. Easy isn’t it? You don’t even need any extra tools for this. I do remember the days I used to lick the batteries to test whether they have any charge or not. LOL, funny days. 😛
Go ahead and try this with your batteries. Do let us know your views in the comments below.
