Many contemporary solar installations utilize no-maintenance AGM batteries. They are rated safe for use inside your rig, so there's no need to mount them outside or remove them to avoid casual theft - they can be mounted under the dinette or inside of cabinets at any angle without water levels to check, battery trays or venting. And their many advantages can mean their higher cost is worth the payback.
To be correct, there is maintenance. Per Deka / East Penn, my preferred mfgr; annually, you want to at least go look at them! :)
Seriously though; if you have not observed any loss of capacity over the previous year, you can skate by for another year without peeking. The main reason for checking is to assure that connections are secure.
There has not been any credible proof that AGMs are more expensive, after purchase, over time. IMHO, wets are chaper to buy, but more expensive to own.
