Yes it can produce Hydrogen-Sulfide, but usually only if overcharged (which may be your case). There is a write-up at the Battery University Website which talks about it: Over-charging a lead acid battery can produce hydrogen-sulfide. The gas is colorless, very poisonous, flammable and has the odor of rotten eggs.
Over-charging a lead acid battery can produce hydrogen sulfide. The gas is colorless, very poisonous, flammable and has the odor of rotten eggs. Hydrogen sulfide also occurs naturally during the breakdown of organic matter in swamps and sewers; it is present in volcanic gases, natural gas and some well waters.
Turn off the charger, vent the facility and stay outside until the odor disappears. Other gases that can develop during charging and the operations of lead acid batteries are arsine (arsenic hydride, AsH 3) and (antimony hydride, SbH 3).
And yes, I charge my car batteries in a well ventilated area so Hydrogen gas build-up is not an issue. It's he corrosive Hydrogen Sulfide gas that concerns me. Yes it can produce Hydrogen-Sulfide, but usually only if overcharged (which may be your case). There is a write-up at the Battery University Website which talks about it:
Flooded lead-acid batteries (e.g., used in some electric forklifts) contain an electrolyte solution of sulfuric acid and distilled water. During normal operation, the water evaporates and needs to be refilled (watered) to keep the battery operating effectively and safely. Use distilled water. Do not add sulfuric acid to the electrolyte.
Lead acid produces some hydrogen gas but the amount is minimal when charged correctly. Hydrogen gas becomes explosive at a concentration of 4 percent. This would only be achieved if large lead acid batteries were charged in a sealed room. Over-charging a lead acid battery can produce hydrogen sulfide.
Proven Success Across the Globe in Diverse Sectors

Actually SLA batteries have a vent... so the name "sealed" is a bit of a misnomer.VRLA (valve-regulated lead-acid battery) is actually a name for the same tech.. Practically every UPS (uninterruptible power supply) I know of has one [or more] SLA[s] inside, so it''s generally safe for indoor use.
The most common form of a lead acid battery is used in cars and trucks.Golf carts and electric cars and the like also use lead acid batteries.Essentially, every lead acid battery works the same way.
In acidic electrolytes voltage above 1.23 V is enough to split water into oxygen and hydrogen. This makes lead-acid batteries thermodynamically unstabl,e however the system works successfully with typical open circuit voltage more than 2 V. This is possible due to outstandingly high overpotential slowing down hydrogen evo-
you need to add water to "wet" (flooded type) non-sealed lead acid batteries. 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−
