I have been wanting to post this question for some time but time restraints and fear of board police have restrained me, but here goes.
I built my battery shed over 5 years ago, concrete floor, plasterboard lining( 1st big mistake) fiberglass insulation custom orb sheeting outside. It has a seperate area for the inverter, which is just fine, the battery side has worked so far but has many short commings.
I obtained my batteries 2nd hand, some 120 plus of them, a semie load actually. I measured them beforehand and made racks out of steel with construction ply as a top, they all fitted but...
Allan did not weigh these beasts, 60+ Kg/battery, right at the extreem of my lifting capability. The racks have two lower groups and two upper, there being two racks so 8 banks. Oh and the I moved in another set along one wall, and the spares at one end.
They were about 13 years old when I obtained them so I reconed if I had two years out of them I would be happy. Here we are 5 years on and still going strong, albiet not without some ongoing maitenance, in particular the casings fretting and allowing acid to escape. So I have a perminante rotation of batteries for repair, but you get that on the big jobs.
So what would I do differently.
Well I would not line the shed as here we have a very moderate climate so if it got down to 0 deg. C I would be worried, yea it gets hot but...
I would give myself much more room, bit hard carrying a 60 kg battery full of acid and tripping over things.
I am not sure if I would have future batteries at floor level (most probally) or elevated for ease of checking. As any future battery sets will be new I guess ther will be much less maitenance needed so on the deck makes sence.
If I had second hand batteries again (flooded lead acid) I would seriously concider having plastic trays made. But that can not happen as the government in their wisdom have decreed that only licenced dealers can buy second hand batteries, among a range of other dangerous goods. Though shall not reuse batteries!!! got that, we in government know best whats good for you.
So what if anything would you do differently?

Moved to "storage" where it seems you wanted it and where it should be.
Your bored board police .
