@AuroraGirl, SirRobyn0, Ellie Niner,
Man, thanks so much for the detailed info. I was hoping that this post would turn out to be a bonus on info because I joined this forum because I didn't know so much that I thought I knew a lot about but really didn't. You know how that is. You hear so much over decades that you think you know something but you don't ever know as much about as you find out.
See, that's what I was wondering about the sealed "low Maint." batteries. Just how "low maint." are they if you can't get into them without messing up the sealing,
@AuroraGirl, and you wouldn't want to do that if for the mere fact that if anything did happen you might not get your money back because it might look like you tampered with it at the very least. That's why I bought the capped type so I could check the fluid level and I regulaly check the specific gravity in each cell with one of those glass and colored ball checkers. I prefer them over the all plastic ones, which I have also but use the glass checkers all the time.
I have to admit that, yeah, I'm one of those guys who used to use tap water to refill my batteries. But no more only on account of what I've since learned here some time ago. I thought, what the hack, water is water and didn't seem to not have any problems using tap water.
