Not disagreeing that it is a flooded wet cell battery but it is designed to be maintenance free - That is it is not vented and you should no remove the cap. It does have a vent for when the battery does get overcharged and it will vent.
And not trying to be argumentative but these batteries (and I have used many) will last 10 years if properly maintained with <30% discharging.
I agree 100% that if used as a "deep cycle" ~50% + discharges you can expect to buy new ones every 3-5. On boats where you can have an 8 battery bank, battery life is a really hot topic. Boat guys freak out when they have to spend >$1,300+ for a new set of Trojan t105s.
But again - I am learning the expectations of the RV world are a lot different.

Gary RV_Wizard said:Not an AGM. An AGM is totally sealed and would not have the removable caps on top. That is a basic Marine/RV flooded cell, which is a slightly modified car starting battery design. In RV Use, it has a useful life of about 3 years if lovingly cared for and as little as 16-18 months if not.
