Why recast it? Drill it and put in a bolt. Especially if used only for

I don't have the molds (or talent) to make a new post. When I've had
them melt off, I took them to an "old timer" at a big industrial battery
store. He made a new post in just a matter of minutes. He made it look easy!
So I tried it; I just turned postless batteries into useless batteries. :-(
I also tried buying an "adapter" to convert a side terminal battery into
one with normal automotive posts. This is basically a steel bolt
embedded in a lead automotive battery post. They expect you to screw it
into the threaded hole in the side of a side-terminal battery. I
threaded a hole in a partially melted post, and screwed in the adapter
(plus plenty of grease that was supposed to keep the acid out). It only
worked a short time, and then rapidly corroded into junk.
I think the ideal solution is to weld your wires directly to the
battery; no post or terminal at all. I *have* successfully dunked the
wire or battery bus bar in a solder pot, then welded it to a battery
post (just heat until they flow together). My connections looked ugly,
but never failed again.
