Let's face it, watering the house batteries in any boat is a pain in the
ass. Dragging out all the stuff on top of the battery boxes....crawling
around inside awful compartments full of engines, water heaters and much
nastier crap to peer down inside that very back cell you wished you'd never
put where it is.....we've all been there, done that, cursed and hurted.

Water all the batteries at once with valves to level each cell just right.
What a cool idea.....

A lab wash bottle and inspection mirror are effective and much more
versatile.

How do you get to the back cell of the last battery against the back wall
of the engine room better with that?

Hell, this thing can be plumbed easily so you can fill the batteries from
your bunk, if you want...(c;

Does this have a small float switch for each cell or does it depend on
water seeking its own level?

In the latter case, how does it work on a heeled sailboat?

It was reported recently in an RV bulletin board that they felt that
the batteries were being over filled. This could perhaps be due to the
vehicle motion.

You only fill it with a squeeze bulb once in a while, not continuously.
There's a float valve in each plug that shuts off the water when the level
gets below the filler. The rest of the time it's a safety vent.

The level in a heeled sailboat is the same as it is, now. The plates on
the high side are exposed to the air as the electrolyte levels with
gravity. The vents in the middle of the cell don't get messy until you
broach or pitchpole the boat upside down. A sailboat battery is always the
wrong way....a topic we haven't explored much worrying over why $800
batteries are better than $65 batteries. I suppose AGM or Gelcell
batteries are better than wetcells in a heeled over sailboat, but it never
seems to make a difference that I can tell, because there's always lots
more lead in the plates than there is electrolyte to eat them.
