Lead acid batteries suck. The price is very high. They are disposable after about 7-10 years. They are full of toxic materials like lead and emit toxic gases. They also require gentle care and the slightest snafu will destroy all of them. I have done a bit of research into the Thomas Edison nickel iron batteries. They seem low tech, safe, cheaper, and they get better with age. I worked on the railroad and they had some from the land before time that still did a great job. (I'm guessing 40's) They lose charge quicker than lead acid, but if it lasts for a hundred years does it matter? Holy crap are they heavy, but they can be treated like crap and still work wonderfully. Some of the methods used to make nickel iron batteries seem doable. I have seen folks on youtube making tiny versions only. I have read the few posts on permies regarding them. Great reading, but the only options seemed to be Edison batteries, the commercial route. $1k for a 12 volt 100 amp Edison. One of the biggest costs would appear to be nickel at first glance. I do pottery and powdered nickel is not very expensive. I would put 200 toward a good how to video or a horrible failure with lots of expletives.
As a lover of all things conspiracy I'm guessing the Exide company stopped making these batteries because they lasted too long. It didn't work with our planned obsolescence society. Enter the compact fluorescent.
