How To Make An Emergency Battery From Things Around The Home

If you need some electricity to run lights, there’s a lot of options from the things you’ll find around the home. In this video, Robert shows a simple Iron battery you can make from steel wool and brick cleaner.

You’ll need a carpenter’s pencil, a cup, some activated charcoal, and some paper for a separator.  It uses brick cleaner but can also run-on bleach or vinegar. This battery can run for many hours. Join ten in series to run LED lights. Each cell is around 0.3 volts.

The battery has issues, be careful with brick cleaner and use ventilation as it produces hydrogen but works well as an emergency battery.
