I am using Super Start 31 DCMJ Standard Lead-Acid batteries for my solar setup and I have them setup under cover of the nose of my 5th wheel RV. Yes, they are somewhat exposed to the weather but only in terms of the outside temps, they do not get wet. And I am well aware this is not optimal for any season, but that is why I am asking. Also, they aren't sitting directly on the ground. I have them sitting on a few 4x4 pieces of wood so they are 4" off the ground. I have read enough to know I need to get them enclosed and insulated somehow before winter, so I am looking for best suggestions based on what I have available. I am currently living in a 5th wheel RV on my property until my house is built and enclosed spaces are extremely limited. The manufacturer says these batteries are maintenance free BUT that you CAN add distilled water if absolutely necessary (doesn't sound very maintenance free if you ask me). So, I can only assume that based on this, they are not sealed and need a ventilated space to keep them in. Temps here are supposed to get as low as the 20's (F) during the winter months. Would it be sufficient to build a wood box and use foam board to insulate the box, while still keeping it outside under the cover of the nose of my 5th wheel? I also thought about the possibility of using a cooler like an Igloo or something cheap that I wouldn't feel terrible for drilling holes in it.
Any suggestions are appreciated! Thanks!
