I got 2 units of solar lantern lamp from a friend to test.They are made in China. One of the lantern is modified so that it has a charging and low power indicator. I put a simple charge controller inside it and a brand new Panasonic 6V 4.5AH Sealed Lead Acid Battery. The other lantern is kept original. I want to compare which one has better performance. Both have been put into test since the beginning of June 2008 and are still working just fine. I charge them whole day from dawn till dusk (effectively from 6:30 till 17:30).

A quarry worker in Seoul was found dead. Police found a melted cell phone battery in his shirt pocket. They believe that the battery explosion was the cause of death. The Doctors said that the man hard a burn on his left chest side and his ribs and spine were broken. The explosion must have damaged the heart and lung.Personally i don't think that a battery explosion could have been so powerful to kill a human and break his ribs and spine, even if it had exploded next to a man chest. Maybe the battery burned him and he tripped and fell a long way. That would explain the broken bones.
