100 Happy Days Challenge - Day 31

Learned a simple way to test dead batteries today.  BuzzFeed created a short video to show us an easy trick. 

Pick up your battery and drop it on a hard surface straight down.  If it bounces and falls down, it is a used one.  If it stays upright on the hard surface, it is a new one.

Life is easier now without using any battery tester.  All you need to do is drop your battery on a hard surface.
