#1 cause of swollen batteries is overcharging.
Make sure you check that your inverter/charger is properly programmed/dip switches set. Programming includes telling the inverter/charger: Battery type (wet, gel, AGM), battery bank size (amp-hrs) and if no battery temperature sensor, ambient temperature.
Freezing of a discharged battery will also cause swelling, but again only of a discharged battery in well below freezing temperatures.
