Re: Stus-List Battery compartment and battery boxes. SS straps?

2017-05-22 Thread Della Barba, Joe via CnC-List 
I have gels now not in boxes. Putting them under water generates a small amount 
of chlorine from electrolysis of salt water, but not much. Getting salt water 
mixed with the acid in a wet cell makes much more chlorine and generally 
stinks. I can still smell it…

Agreed Joe but if you are using AGM, or Gel, or glassed in the compartment then 
you've already created a leak tight space.

The only other vulnerability which proper battery boxes address is flooding and 
the generation of chlorine gas when sea water contacts the terminals.  The 
boxes create an air pocket/loop seal which allows ventilation normally but 
prevents water from entering... Assuming the boat stays level.  Most people 
defeat the covers by drilling holes in them or not using them and everybody 
else says, "If water gets that high then I have bigger problems than batteries 
to worry about."

The battery box does provide the function of preventing terminal shorting,
but so do many battery compartments lids AND terminal boots.  I'm not
opposed to a belt and braces approach but when only one it needed there is
no reason to sacrifice space.

As for ratchet straps, if its for batteries inside the boat I say let the
cheap ones rust.  10 year from now I'll buy new cheap ones.

Re: Stus-List Battery compartment and battery boxes. SS straps?

2017-05-20 Thread john sandford via CnC-List 
I like the ratchet strap idea.

Mine are gel, no box, and the crummy plastic CTyre strap.

Does anyone know where to get ratchet straps, in general, with SS hardware ?

Batteries, Dingy to dock, float removal and securing, etc. many more 
applications.

Thanks for any guidance.

I bought kayak straps.

But you could use ratchet straps too.

I wanted to avoid putting anchor screws in the lower part of my compartment.  
Seems kinda counter productive to epoxy in a box for leak tightness only to 
then put holes in it for fasteners.  I bent some flat aluminum bar stock so 
that it follows the contours of the inside of the battery compartment.  The 
bars are held in place at the top of the compartment.  My straps are fed 
perpendicular under the bars and the batteries sit on top of both.  The straps 
wrap across the top of the batteries and meet on the side.

 

The load requirements are side to side movement of less than an inch and mounts 
which can hold 90lbs.

Commercially available plastic battery boxes provide a means of restraint and 
insulation of the terminals.  Properly made and used, the battery boxes also 
provide a means of catching acid if it were to leak out.  The lids are designed 
to maintain a loop seal which prevents water from getting in the box should a 
flooding situation submerge the box.  Sea water and batteries is a bad 
combination which can, not just short out and destroy the battery, but also 
generate chlorine gas.

 

I don't have commercial battery boxes in either of my battery compartments.  
The batteries are strapped down.  The compartments are glassed in to provide 
leak resistance.  The compartments have wooden lids which prevent inadvertent 
contact with the terminals.

 

I think you are ok removing the plastic boxes.
