That's probably OK if you're very careful.  But I don't think most people 
should let it go that low, especially with the battery boiler these 
tractors 
use as a charger.

First, you're just too close for comfort, without enough margin of error.

Second, you're increasing the electrolyte concentration.  I don't know 
that 
it's a huge difference, maybe not even a significant one, but it does 
change 
the balance between active material capacity and electrolyte capacity.

You needn't (and probably shouldn't) fill all the way to the split ring, 
but 
I'd keep the level within a half-inch or so of it.

Sounds fine.  Like any other base, just be careful not to get any in the 
cells.  

I clean battery tops with dishwashing liquid (usually Ajax), a toothbrush 
for the little crannies, and water.  However, since I'm using gel 
batteries 
in my ET, that's not really an issue.  I just wipe them down now and then 
to 
remove the accumulated dust.
