Firstly , Batteries over charging ( batteries charging voltage are too high)
Secondly .batteries powered off , charging current of the batteries is too high
So for the agm batteries or the Sealeadl lead acid batteries usually suggest customers to use a good charger ( a good charger controller , a good inverter) to make sure your batteries are charging properly and it’s very important. 
Thirdly , Positive and negative were connected reversely, then load short circuit would cause the batteries swelling as well.
That’s all reasons may cause swelling. Hope above tips may helpful for you to avoid this kind of problem during daily use.
