Yes, it's the same thing with all "lead acid" batteries. Even today's sealed batteries can start leaking gas around the terminals or develop a small crack in the case. To help prevent the white stuff from forming, you can remove the cables from the battery and clean the cables and terminals with a wire brush and apply a anti-corrosion paste or petroleum jelly to the terminals when you re-install the cables.
