Re: [RE-wrenches] Acid containment
Bill, Off the shelf plastic tool boxes also work, we’ve used those in the past. You wouldn’t necessarily need to build a wood box around the plastic tool box(es) since they will hold up on their own. It all goes back to the size and number of batteries that you need and whether you can find a box that has appropriate dimensions. You’ve probably already considered this option, but I thought I’d mention it anyway. See attached pic as an example.

Re: [RE-wrenches] Acid containment
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.

Re: [RE-wrenches] Acid containment
Hi Bill, Think spray-on. Build your box then spray on the liner. Have you seen spray in box liners for pick up trucks? It's pretty tough stuff and I would think that it would be able to hold acid. There are plenty of places, at least around here (Alberta), that do this and I'd also think that you could buy/rent what you need to do it yourself, onsite.

Bill, I have lined our plywood battery boxes for many years with 6 mil polyethylene sheeting. I do two layers, neatly fold the corners so it form fits then run it up the side walls about 10 inches only and staple the poly to the plywood. To protect the poly liner from the weight of the batteries I use 1 x 3 softwood strapping that I sand down so no rough edges will damage the poly. I first spread out a small amount of baking soda on the bottom of the battery box (on the plywood) before installing the poly liner, then on the poly before placing the batteries on top of the strapping. Two runs of strapping for one row of batteries and four rows of strapping for two rows of batteries. This is simple and cost effective method that has had excellent results over the years. Recently removed the second battery bank from a twenty year old battery box set up in this method. We removed the poly liner for the first time and we found the 3/4 plywood to be in good enough shape to use for the third set of batteries. - Dave David Palumbo Independent Power LLC 462 Solar Way Drive Hyde Park, VT 05655 802-888-7194 -Original Message- From: RE-wrenches [mailto:re-wrenches-boun...@lists.re-wrenches.org] On Behalf Of frenergy Sent: Monday, March 30, 2015 12:04 PM To: RE-wrenches Subject: [RE-wrenches] Acid containment Fellow Wrenches, I just called Tap Plastics hoping they would solve my problem of battery acid containment within a plywood battery box. 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.

Acid will eat spray on bed liner too R.Ray Walters CTO, Solarray, Inc Nabcep Certified PV Installer, Licensed Master Electrician Solar Design Engineer 303 505-8760 On 3/30/2015 10:36 AM, Benn Kilburn wrote: Hi Bill, Think spray-on. Build your box then spray on the liner. Have you seen spray in box liners for pick up trucks? It's pretty tough stuff and I would think that it would be able to hold acid. There are plenty of places, at least around here (Alberta), that do this and I'd also think that you could buy/rent what you need to do it yourself, onsite.

Re: [RE-wrenches] Acid containment
We have used the underlayment material to line battery boxes. Turns out it gets eaten by the acid too, not recommended. Really the best product I've ever used is just the heavy plastic sheeting to line the inside of the box. I had batteries crack and leak acid almost 2 inches deep, and the plastic sheeting held it. We try to use large plastic tool/ cargo boxes. The auto parts single boxes are not a good idea for more than a single battery: exposed cables and jumpers.

[RE-wrenches] Acid containment
US Plastic (usplastic.com) carries polyethylene tanks used in industry for acids. You can get them in various sizes - 24 x 36 x 20 deep and larger. They will custom heat weld whatever you want. Kind of pricey (~$300) but heavy duty. Hilton -- Hilton Dier III Renewable Energy Design Partner, Solar Gain LLC 453 East Hill Rd.
