Positive battery terminal repair?

[JMAC]

I just cracked the terminal in my used-to-be-my-grandfather's '69 Mercedes 250. Any chance the lead could be soldered back together in place and hold? I don't want to buy a universal terminal...the old one has patina!

Why take that chance with a high current battery terminal?

I think Mercedes advertises that they sell parts for their vintage cars so you very well may be in luck there. Any MB dealer should be able to help you out. Being a vintage Mercedes, I'd imagine it best to bring money....

Best Regards,
Mike

give us a picture of the crack. ;-)

seriously, check old junkyards for old terminals (on old cables). You can shorten a long cable by putting a modern lug on the non-battery end.

What's the big deal? Buy a new battery. It's a '69 Merc, not a Bugatti.

Lots to be said on a bit of solder.
Just do it.
Put better insurance on it though..')

I have had success drilling out the post (I assume that is what you mean by terminal) and threading it, and inserting a threaded brass rod, and hooking the clamp to that. i would not ever solder a terminal. I know of one case where someone did so successfully, with a torch. I know of a case where it was not successful, too.

I have a die set for recasting tapered battery posts. Positive and negative posts are different.
You have to melt new lead into the die with a small (hot) torch to alloy it with whats left of the old post. I use an oxy-acetylene torch, maybe a #1 tip.

Seems my exploding battery thread was timely! Yes, that's exactly how I replace cells in forklift batteries. Remember to make sure the battery has not been on charge for at least 6 hours. Remove the vent caps a couple hours ahead of time and give the battery a little shake to dislodge hydrogen bubbles.Keep the vent caps off during the proceedure, if you do get ignition, you get a pop, not an explosion. Wear a face shield. For those who didn't see, this happened on my boat last week:

I don't mean the post, rather the terminal around it. I called M-B this morning and got a price of $130 for a complete cable with connectors. On the other hand I bought a universal replacement today for $1.44. So much for authenticity...

It's done and the old girl runs. My grandfather bought it new in '69. I loved it then, I love it now.
