Gases produced or released by the batteries while they are being charged can be a significant safety concern, especially when the batteries are located or charged in an enclosed or poorly ventilated area, or on the truck. Flammable Gases In an area where lead acid batteries are being charged, the first gas to measure is H2.
Fire engines, HAZMAT and emergency response vehicles frequently include banks of lead acid batteries for the same purpose. Gases produced or released by the batteries while they are being charged can be a significant safety concern, especially when the batteries are located or charged in an enclosed or poorly ventilated area, or on the truck.
Lead-acid batteries will produce little or no gases at all during discharge. During discharge, the plates are mainly lead and lead oxide while the electrolyte has a high concentration of sulfuric acid. During discharge, the sulfuric acid in the electrolyte divides into sulfur ions and hydrogen ions.
Overcharging, or lead acid battery malfunctions can produce hydrogen. In fact, if you look, there is almost always at least a little H2 around in areas where lead batteries are being charged. Overcharging, especially if the battery is old, heavily corroded or damaged can produce H2S.
The charging of lead-acid batteries (e.g., forklift or industrial truck batteries) can be hazardous. The two primary risks are from hydrogen gas formed when the battery is being charged and the sulfuric acid in the battery fluid, also known as the electrolyte.
When a lead acid battery cell “blows” or becomes incapable of being charged properly, the amount of hydrogen produced can increase catastrophically: Water is oxidized at the negative anode: 2 H 2O (liquid) → O2 (gas) + 4 H+ (aqueous) + 4 e− The protons (H+) produced at the anode are reduced at the positive cathode: 2 H+ (aqueous) + 2 e− → H2
