It's a myth that AGM batteries don't need to be vented....from the Lifeline manual.....
DANGER OF EXPLODING BATTERIES
Lead acid batteries can produce explosive mixtures of hydrogen and oxygen. Take the following precautions:
Never install batteries in an airtight or sealed enclosure and make sure installation is adequately ventilated.
Charge batteries in accordance with the instructions given in this manual. Keep all sparks, flames and cigarettes away from batteries. Connect cables tightly to the terminals to avoid sparks. Wear proper eye and face protection when installing and servicing batteries.
DANGER OF CHEMICAL BURNS
Lead acid batteries contain sulphuric acid electrolyte which can cause severe burns to body tissue. Take the following precautions:
Avoid contact of the electrolyte with skin, eyes or clothing. Never remove or damage vent valves. In the event of an accident, flush with water and call a physician immediately.
DANGER OF BURNS IF TERMINALS ARE SHORTED
Lead acid batteries are capable of delivering high currents if the external terminals are short circuited. The resulting heat can cause severe burns and is a potential fire hazard. Take the following precautions:
Do not place metal objects across battery terminals. Remove all metallic items such as watches, bracelets and rings when installing
or servicing batteries. Wear insulating gloves when installing or servicing batteries. Use insulating tools when installing or servicing batteries.
DANGER OF THERMAL RUNAWAY
Thermal runaway is a condition in which the battery temperature increases rapidly resulting in extreme overheating of the battery. Under rare conditions, the battery can melt, catch on fire, or even explode. Thermal runaway can only occur if the battery is at high ambient temperature and/or the charging voltage is set too high. Take the following precautions:
Charge batteries in accordance with the instructions given in this manual. Do not install batteries near heat sources or in direct sunlight that may artificially elevate their temperature. Provide adequate air circulation around the batteries to prevent heat build up.
