The charger has two lights, red and green.. no switches no buttons nothing. ( no owners manual or book) Your right obviously when it's green it stops charging the battery.. I guess I really want to know if this will hurt the charger. This charger is so cheap, it came with a slip of paper saying, "Always plug the charger into the battery first Then to the wall or you WILL fry your charger."

When I posted that after 12 am I wasn't thinking straight.. I could have asked the question better.
