When used with a properly regulated constant voltage charging system the battery will normally not produce hydrogen gas. Occasional gassing can occur when charging at higher voltage levels or in extreme high-temperature conditions. In automotive applications, this typically will not happen if the alternator/regulator stays below 15 volts.
