Pushing the envelope with Solar Mesh

Well, the solar Mesh went almost seven days with continuous power. Between 8-9 am today the unit went down. This was third day of cloudy or rainy period. I was amazed it lasted this long. By 9am the mesh came back up by itself because it a bright sunny day. I started to think continuous power put I knew that the battery can only hold out so long. It seems that I will need a second battery and possible another solar panel to keep the batteries charge while running the solar mesh.
