What gases are released when a lead-acid battery is being charged?

Explanation:
Charging a lead-acid battery splits water in the electrolyte into hydrogen and oxygen. The hydrogen comes off at the plate connected to the negative terminal, while oxygen comes off at the plate connected to the positive terminal. The overall process is water electrolysis: 2 H2O -> 2 H2 + O2. This is why hydrogen and oxygen are the gases you’ll observe venting during charging. Other gases like argon, neon, or nitrogen aren’t produced by this normal charging reaction, and any gas buildup should be vented safely in a well-ventilated area to avoid fire or explosion hazards.
