We once cooked a T105 in an Electric vehicle situation, where the
terminal was loose and cause the lead around the bolt to melt. They're
just bolts set in lead. I removed the original bolt, and then drilled
and tapped into some solid lead to the side of the damage. I was able to
screw in a 1/4" stud, and make the battery operational again. (Don't go
too deep, Boom!)
I later sold the battery at a significant discount to a DIY friend. It
worked fine for him, but you don't want to be setting up a regular
customer with something that MIckey Mouse.
Seems like the battery manu owes you a battery, I've had over 1000
batteries installed, and I never had a new post do that (of course I use
WIndy Dankoff's magic battery butter (vaseline)on everything during
assembly)

Benn,
What I am talking about is welding the lead cell interconnects between
battery cells. Not welding cables to the lead posts, that would be a
recipe for disaster.
As far as the galling threaded post, if you try to cut it off it might
wiggle enough to break it internally, nothing good down that road. If
you cut it off is there enough room to get a nut and lock washer on
the remaining stud?
Overall the easy cure is probably replacement, anything else is iffy.
But if it works it saves you the cost of a battery.

*Subject:* [RE-wrenches] Battery interconnect cable length
Thanks for the feedback guys.
Yeah, i suppose that in a single string, cable length is not as
important as it would be for the paralleling cables.
Ray, good point that if there are multiple parallel strings, then the
series jumpers in one string should be equal length to the series
jumpers in each string. I see the logic in that.
Daryle, 'right-angle lugs', i've seen those. Good suggestion for
difficult connections, thanks. I'll have to keep a few of those handy
for future jobs.
Bob, are you saying that you weld the interconnect cables to the
battery posts? and/or use 'plates' to bolt the posts together? I've
seen plates used, but welding the lugs to the posts ....? ... see
next thread.... 'Battery Post Galling'
