My son dropped a phone. The lithium battery exploded and it freaked him out. The phone will only stay on for a few minutes before it overheats. I remember when I used to believe rechargeable batteries were safe and environmentally friendly. We’ve got billions of those little devils now. They make big ones for cars which also explode and burn for days. We need to rethink what we are doing with electricity before the whole world catches fire. Lithium Batteries were supposed to save us from that but the evidence is to the contrary.
