Battery post melt down

[Davidwyby]

That would basically amount to a "cold solder" joint since you would not be sufficiently heating the substrate metal (lead post). The bond between your solder filler and the lead would be very weak. This fix would be "cosmetic" at best.

The terminal clamps cold. The solder would fill the gaps and restore most of the contact area. Can't see calling it cosmetic only.

The post and clamp could be preheated. Solder melts at ~half the temp of lead = safer.

Solder melts at ~half the temp of lead = safer.

Try it. But I think you will find your solder in a puddle under the clamp next time you try to start the truck.

Ah, yes, I see...if the joint doesn't conduct well, the solder will melt out "in a flash".
