In recent years, lead acid batteries have been replaced by lithium ion batteries in many applications. This is a result of the lithium ion batteries having a greater energy density, efficiency, and lifespan as compared to lead acid battery chemistries. These batteries, however, are capable of storing large amounts of energy and often utilize a volatile or combustible electrolyte and thus are prone to fires and explosions. As a result, significant testing has been conducted to identify the fire hazards associated with lithium ion batteries. However, little testing has been performed on the lead acid battery chemistries.
