Protecting Battery Rooms with a Hydrogen Gas Detector
If batteries are charging accurately, then the majority of battery technologies are recombining the hydrogen internally. However, as a battery degrades or the charging cycle is not running optimally, the battery will begin to liberate more hydrogen than necessary (note all lead-acid batteries free hydrogen to some level).
Hydrogen Management in Battery Rooms
Vented Lead Acid Batteries (VLA) are always venting hydrogen through the flame arrester at the top of the battery and have increased hydrogen evolution during charge and discharge events. Vented Lead Acid Batteries (VRLA) batteries are 95-99% recombinant normally, and only periodically vent small amounts of hydrogen and oxygen under …

Why are Li-Ion battery so much safer than lead-acid?
Lithium Ion batteries when being charged do not usually liberate hydrogen or release electrolyte. Both are possible, but only if a damaged or incorrect charger is used. In exchange for not doing these things. instead they occasionally catch fire and "explode" - actually not a true explosion.
Battery Room Ventilation Code Requirements
Battery room ventilation codes and standards protect workers by limiting the accumulation of hydrogen in the battery room. Hydrogen release is a normal part of the charging process, but trouble arises when the flammable gas becomes concentrated enough to create an explosion risk — which is why safety standards are vitally important.
