If you call up a chemical resistant chart the options are not huge PVC is good that's why battery vents are PVC.
On the EDPM: you fold & only cut up high! I was thinking on this and you could lay the EDPM down folded up & tacked on the back & sides and then lay down a sheet of plywood to "protect" the EDPM from getting damaged as you move your battery bank into place, then pull the front EDPM up, attach the front panel and secure the EDPM to the upper inside front panel. It's like origami or making an envelope out of a flat sheet of paper. ---------------------------------------------------------------------------- Dana Orzel Great Solar Works, Inc - NABCEP # 051112-136 E - d...@solarwork.com - Web - solarwork.com O - 970.626.5253 C - 208.721.7003 - No FAX Line "Responsible Technologies for Responsible People since 1988" P Please consider the environment before printing this email.

I've seen the PVC shower pan material...we'll see if its wide enough for our application, I always banked on about 3" up the side of a battery box would hold many gallons of acid. Benn, I did a search on this in the Wrench archives and someone mentioned the spray liner would soften (and then fail?) over time when exposed to acid.

Do you seal/adhere it somehow? With what? Or do you find that you can get the liner sheets large enough that you just 'stuff it in' (for lack of a better term), and then in the corners do you just double it over to make a tight fit? Or make cuts in the corners...?

I was surprised by their response that the acrylic was not impervious to acid and polyethylene would not work because sealants nor caulking adhere to it properly. They did not have anything that would work. I've used those individual battery boxes from an auto parts store (~$12/each) but they take up more space than just the batteries. Has anyone ever used ice dam underpayment, like Grace? Better idea?
