The Li ion Battery Failure detector protects Li Ion battery rooms and other locations where motive and stationary batteries are present by monitoring hydrogen gas levels. Li Ion batteries emit hydrogen gas first during a runaway condition.Concentrations of 4% with air can be explosive The detector turns on the fan at 0.25%, or 135Deg F. Sparks or hot surfaces can ignite them. The hydrogen gas detector will provide a warning and facilitate dissipation of the hydrogen, by operating alarms and exhaust fans before it reaches the lower explosive limit of 4%.
