How to Make Your Own High Speed Solar Battery Charger
- How to Make Solar Battery Charger ?-First we need an old window, I got mine from a construction site. Its your basic old nasty basement window. Make sure you wash both sides of the glass well with soap and water and window cleaner, more dust means less light gets through to your solar cells.
Next take your multi-meter and sit in a sunny spot (or under a flood lamp) and check all your cells to make sure they get about .5 volts per cell. You do this by gently (cells are REALLY fragile) putting the red on the front (make sure its on the little metal lines) and black on the back (any place) of each cell while it is in the sun. It should say about .5 volts. If you get a really bad one don’t use it as it will lower the power of your charger.
