Opening the housing usually destroys the gasket because it sticks to the lid or the housing. This causes battery maintenance problems because in order to seal the housing again, a new lid with sprayed-on gasket is required. This is the reason why large-scale gaskets are used when tough technical require-ments need to be met.
