During charging, these batteries produce oxygen and hydrogen by the electrolysis. When a lead acid battery cell “blows” or becomes incapable of being charged properly, the amount of hydrogen produced can increase catastrophically: Hydrogen is not toxic, but at high concentrations, it’s a highly explosive gas.
• Connect via MODBUS (RS-485) or 4-20mA During charging, (especially in the event of overcharging), lead acid batteries produce oxygen and hydrogen. These gases are produced by the electrolysis of water from the aqueous solution of sulfuric acid. Since the water is lost, the electrolyte can be depleted.
At this concentration, all it takes is a source of ignition to cause an explosion. Sparking from a battery terminal as it is connected or disconnected from the charging system is more than adequate as a source of ignition energy. That’s why lead acid batteries should only be charged in well ventilated areas. Toxic H2S

The leakage of sulfuric acid was the main environmental risk of lead-acid batteries in the process of production, processing, transportation, use or storage. According to the project scale the sulfuric acid leakage rate was calculated to be 0.190kg/s, and the leakage amount in 10 minutes was about 114kg.
Ingestion of vegetables and inhalation are the main exposure pathways. In recent years, environmental pollution and public health incidents caused by the recycling of spent lead-acid batteries (LABs) has becoming more frequent, posing potential risk to both the ecological environment and human health.
