Checking "Fluid Levels" on a newer battery.

I'm seeing people advising owners with battery issues to "check the water level" or the "fluid level' on their batteries.
If this was 10 years ago, or batteries still had covers on the cells that were easy to pop off, I'd say go for it.  But on the last few batteries I've bought, and the newer batteries in my cars, it seems that this "old skool" method has bit the dust:  those cell covers are simply too difficult to remove, it seems to me.
Is "checking the fluid levels" even possible any more?  Is it still good advice to give to a novice battery user?

    If you have the. Ever sealed batteries, you do not check fluid or top the fluid level,off.  They are “sealed”, and are not traditional lead acid batteries.  This is one of the advantages of sealed batteries, no maintenance.

    And if you have a traditional wet cell battery--still very common with inexpensive but perfectly functional marine/deep cycle batteries--then yes, you should check the levels occasionally. 

    You don't need to obsess about it, just make sure the fluid level stays above the top of the plates.

    The lead acid deep cycle Interstate battery that came with my T@B had two caps that could be pried off to check fluid level.
