Main Question or Discussion Point
I would like to implement my own battery to power a computer monitor and a CPU for 12 hours before being recharged. The condition is that the power leakage must be less than 300 micro watts. I would like to know the steps involved in making my own battery to perform this task? I would also appreciate it if I could get material on this subject as well as the power conversion like converting from AC to DC etc involved in making this battery.
