The wires to the battery on my lawnmower were repaired by the PO with crimp connectors, but they were too small for the gauge wire. I went to Lowes looking for a solution and found MECHANICAL LUGS. So awesome! How did I not know these existed before?
generally we don't give that information out... unless you know the secret handshake.
E36 M3, they're in the mechanical lug aisle.
KILL HIM! HE KNOWS TOO MUCH ALREADY!
I used one of those on an alternator charging wire year ago. I bet that connection outlived the truck.
That looks like a corrosion failure waiting to happen. Sure you get a good mechanical connection now, but green death in two years.
Now, if there were a way to pack it in jelly and heat shrink it...

Liquid brush on electrical tape helped when we had to keep patching the power line on the island house. 2 heavy coats did a spectacular job until the next beaver bit through it. I still have nightmares of that house.
Looks like a grounding lug.
ive always used this on terminals and it does a great job of keeping the crusties away, there is also an equivalent cleaner that works well if the crusties are already present.
you can buy fancier versions from places that sell car audio stuff.
?
Enclosed environment perfectly fine. Someplace the cable wires can rust not on your life.
Solder lugs and heat shrink is the way to go. Or buy a proper battery terminal crimper and the correct size lugs.
Or a crimp style lug and moosh it down with Vise-Grips. Just don't forget the heat shrink.
I like the liquid electrical tape strategy, though. I keep forgetting about that stuff.

i made a crimping tool for doing battery cable lugs out of a couple of pieces of steel that i machined for one to fit inside the other... you put the cable in the lug, then the lug in the crimper, then you hit it nice and hard with a big hammer.. it works really well for something i made in 10 minutes on a Bridgeport at work while a part was running in the cnc..
Yes, but how much did the Bridgeport cost?

free... i was at work..
I cut plumbing copper tube, smash one side with the vise, drill or punch a hole in that side and insert wire in the other side and mash in the vise or with a hammer.
This is what i use to make butt connectors. Copper tube comes in all sizes connectors do
