<div class="moz-cite-prefix">Add to the list...I've had good luck
with Grace roofing underlayment: tough and to a degree,
self-healing, sticks to itself (and anything it comes in contact
with) very well making seams secure, easy to find at building
supply store, sticks aggressively to battery box sides without
mechanical fasteners, experience has shown it resists acid. As
with other solutions, something to uniformly distribute the weight
and irregular bottoms of batteries should be employed.<br>

Ray,<br>
Just a couple of weeks ago we installed a 24V HUP set in an
existing installation. We had an existing plywood battery box made
of Baltic Birch (the 9-ply 12mm thick plywood typically used for
cabinet drawer carcases) with a liner made of 40(?)-mil pond liner
material. We removed the six cells from the steel case, set the
case in place in the plywood box and lowered the cells into it.
However, the box had a non-removable 5" wide strip across the top
rear, and we needed to slide the entire 1100 pound case back about
8" in order to fit both steel cases.<br>
<br>
Before setting the steel case in the box I sprayed the floor of
the pond liner with a layer of the new spray pulling lube from
Klein Tools, then set the steel case in place and lowered the
cells. Using a Porta-Power and some blocking, we slid the case
into place with little effort. <br>
<br>
You might find that vinyl pond liner works well in a plywood box.
We found it at a Home Depot.<br>

All; <br>
<br>
We're looking to improve our battery box construction, and are
considering using 1/8" think polypropylene sheeting. I've used
small premade boxes before, but this will be for a HUP install,
and we would want to build the box around the batteries after.
Does anyone have experience/ comments on welding plastic? The
alternative would be to just seal the seams with acid resistant
caulking. (silicone, Geocell, ?) <br>
I've had good luck in the past just using 10 mil plastic
sheeting stapled up on the inside of a plywood box, but we will
be scooting 1000 lb batteries around on it, so I don't think the
sheeting will hold up. <br>
<br>
Thanks, <br>
