[RE-wrenches] Rolls Surrette Re-combiner caps.

[Steve Higgins]

Wrenches...

Recombination Caps typically use a palladium plate or balls to help the
recombination process...  The Hydrogen and Oxygen in gas for pass by
the palladium. The Hydrogen and Oxygen attaches to the palladium and  it
rejoins the gasses into a liquid form.

The problem with this process is it can build up quite a bit of heat.  The
nice thing about the water-miser caps is it's made up of many palladium
marbles, instead of a disk.     There are some recombination caps that when
you are charging at higher voltage, or EQ'ing they will heat up
tremendously and will melt to the tops of the batteries. This forces you to
remove the caps during heavy charging, or equalizing as melting caps are
not a good thing, and whats the point of having these if you can't have
them on the battery?

This is why we switched to the water-misers, they don't get as hot and are
made of materials that can absorb a bit more heat and you don't have to
remove them when charging.

If you need help finding these, let me know off list and I'll work with a
distributor near you to get them.
