Question about Varta Blue Dynamic D24

Sorry if i already wrote that but i believe that the message has not been sent. Is this battery VRLA, maintenance-free? Four websites are saying that it is, and no websites are saying it is not, but most of sellers don’t say anything about maintenance. There are fake maintenance-free batteries, caps are hidden under a sticker. There is a sticker on the top of this battery. Are there caps under it or is there a flat plastic top?
