This trick is quite possibly one of the fastest ways to tell whether a battery is dead or not. Before you would have had to put it in a remote to test it or you would have had to use a battery meter. Not everyone has access to a battery meter in their home, but with this trick, you won’t ever need one again. The guy starts by taking a dead battery and a full battery. He drops the good battery on the table and it stands up with ease. It doesn’t rock around and it doesn’t fall over.
He then takes the bad battery and drops it on the table, and it rocks and falls over pretty quickly. This trick works for all different kinds of batteries and it doesn’t matter what brand you have, because now you can tell whether or not your battery has juice in a matter of seconds.
