[VAC] Re: Battery ventilation

[Rik & Susan Beeson <rik@xxxxxxxxxx>]

If your solar system has a charge controller, and you are not equalizing the
batteries, not a whole lot of hydrogen is generated. But you should equalize
them regularly, and during the equalization they generate a lot of hydrogen. You
can get a rough idea how much by how often you need to top up the water
(although this also is a function of temperature). For any enclosed system using
conventional lead-acid batteries, Hydro-Caps are a great investment. They
catalytically re-combine the hydrogen and oxygen, which prevents the escape of
free hydrogen and also drastically reduces the necessity to top up the cells
with distilled water.

Personally, I think a quarter-inch hose is 'way too small for adequate
ventilation, particularly without Hydro-Caps.

OR you can use an AGM battery... which is definitely NOT the same as a gel-cell.
