Gassing can be prevented by ensuring that the water level in the battery remains high and the battery is properly vented - also that the battery charge settings are correct for the type of battery. Stratification can be prevented by controlled gassing of electrolyte - also by using an equalization charge in flooded batteries to re-homogenize the electrolyte.
