Lead.acid storage batteries emit hydrogen while gassing during charge. Hydrogen concentration of 4% to 75% by volume in air, is potentially explosive. The HGDI-DR hydrogen gas detector is designed to provide dissipation and warning before any concentration reaches the lower explosive limit (LEL) of 4%.
