This is part 2 of my stainless steel and Epsom salt homemade rechargeable battery project. Here I show the cell boxed up in a clear plastic container and running my Led oscillator “Penny”. This…
This shows my homemade stainless steel scrubber rechargeable cell after a non-stop 12 day test using ambient solar energy to recharge it. My LED oscillator “Penny” was used as a constant load during the…
.This shows my homemade rechargeable AA powering a one AA LED flashlight. The amp draw is very high on this flashlight and my homemade AA can only power it for a short time. It…
This shows a AA size homemade rechargeable batteries that I reactivated after many months being stored in a dried out and discharged state. The cell was reactivated by dipping in tap water and recharging…
This shows a homemade rechargeable battery that uses no lead. Both electrodes are charcoal coated with manganese dioxide. The electrolyte is Alum and distilled water
I discovered that my portland cement and beach sand battery was somewhat rechargeable. The effect looks to me like how a high value capacitor would respond. I built a second cement battery using different…
This is a homemade rechargeable battery that uses Epsom salt (magnesium sulfate), manganese dioxide, and water. The electrodes are both carbon rods out of a D cell zinc/ carbon battery. The MnO2 was obtained…
This is a Lead / Alum rechargeable cell that is the same size as a standard AA battery. This allows me to use standard AA battery holders and chargers.
This shows a couple of very simple homemade rechargeable batteries that use lead electrodes with an Alum (aluminum sulfate hydrate) & distilled water electrolyte. John Bedini has been successfully converting full size lead acid…
This shows a simple Lead / Alum homemade rechargeable voltaic cell being tested. Two AA batteries supply the energy to rapidly charge the cell and a small pulse motor is the load to draw…
