There are many publications about the danger of Li-ion batteries that explode or cause a fire.
This week a friend showed me his iPhone. At that moment you realize the real danger of such a battery.
The battery pack had ‘grown’ but was not exploded yet.
If you find a battery like this be very careful, it can explode an do lots of harm.
