The reason why new energy batteries are extremely poor
Batteries can heat up if you have a short circuit. Instead of the electricity going through a circuit where it is used up in various ways or resisted, it just goes straight through the battery, and is then conducted back around into the battery again. All of the energy from the battery is released as heat in the battery, and it can get dangerously hot. - Download [PDF]
