I read this recently; a simple battery tester. It says to test if a battery still has life in it drop it onto a hard floor from a height of six inches. If the battery bounces more than once it is empty or dead. If it bounces once and rolls over, it is good.
I just had to test the test using a few batteries that have been lying around the house. Â For some reason, people in my household keep batteries when they suspect they are dead. Â For quality control purposes (I did work in a laboratory for 30 years you know) I also tested some brand-new batteries right out of the package.
The verdict? Â This battery tester seems to work well. Â The batteries I suspected were dead bounced a few times so did not pass the test. They are now in the electronic recycle bin. (batteries should not go into the garbage) Â The new batteries bounced once and rolled over as the picture indicates.
I hope you are all now looking for batteries to test in your home! Give it a try and let me know your results…
That sounds like a cool test to do 🙂 cheers

I have 2 new batteries on the table beside my computer (They’re for my camera; I’ put them one of these days.) so I tried this. It bounced once and fell over. My concern is that batteries don’t last anytime at all any more. The mouse batteries used to last 3-5 months. Now they last 28-32 days. We use a name brand like Duracell or EverReady. I’m thinking of trying some cheap off-name batteries to see if they last better.
I bounced a new battery on my dining room table and it worked. I’m curious to try it when the battery is dead.
