Thermal runaway - How to halt it and recover from it + How to detect it and prevent it

Thermal runaway scares the heck out of many people; especially those that do not know how to detect that the conditions are being set for a thermal runaway. While thermal runaway can occur in most battery chemistries such as lead acid either VLA or VRLA, or Ni-Cad, or Lithium Ion, this paper is going to restrict itself to the VRLA technology.
