Some of these tricks are not new and people have been using them when no other options were available. These are emergency solutions and they will come in handy during a crisis. As with everything related to emergency preparedness, you have to rely on your wits to get out of a difficult situation. It may seem weird to use aspirin or Epsom salt on your battery, but I guarantee it really works.

Here is a little experiment I did seeing whether you can revive a dead 12 volt lead acid battery with epsom salt. I have seen other video’s on youtube where some people had some success with this method so I decided to give it a try on a dead interstate car battery I had laying around.
You should first check the battery lid is not sealed permanently shut. If that’s not the case use a screwdriver to carefully remove the cap from the cells of the battery. Wear safety gloves and glasses to avoid getting battery acid on yourself.Follow these steps shown on the video to revive a dead car battery./prepperswill.
Measure four tablespoons of Epsom salt and dissolve it in just enough distilled water. Mix until you create a liquid that can be poured in the battery cells.Pour one tablespoon of the solution into each of the six cells of the battery. Once you are done, carefully seal the caps firmly.Recharge the battery on slow charge for 24 hours and the battery should be like new.
