The last I heard there were two manufacturers of lead-acid batteries in the country, so you really are choosing warranty and accessibility.
That's what I heard too.
Up until about 20 years ago, there was a battery manufacturer in Tacoma, WA that built huge single cell batteries for the railroad and ferry industries. You could smell the acid from a block away.
They also built custom lead acid deep cycle batteries for sweepers, forklifts, golf carts, marine etc.
They sold the business when it became cost prohibited to meet environmental regulations.
The gentleman who owned the place breathed that heavy gas from the time he was born since both his parents ran the business. He was over 90 and still came in every day until the business was sold! He smoked too and used his cigarette to light the torch that he used to shrink tubing on custom battery cables, inside the gas filled building! Scared the crap out of me the first time he did that.
