Melted battery terminal . Have you ever fixed One? Melted battery terminal

Do what? Your image isn't displaying. Try describing what happened.

IF.....that post/bolt is still firmly attached, just make sure it's clean and tight and forge ahead. Being loose is probably what cause that in the first place. Or you could get an adapter that bolts to the OTHER POST.HOWEVER.....the heat might have melted a connection INSIDE the battery too.If you really care about battery reliability, I think you should get a new one.

how did you get that hot?is that the original battery cable?or a replacement ?if the battery tests goodtake a file, flatten it out and call it goodany heat to melt and reform the lead post is just going to cause more damage to the battery

Melted terminal VS exploding battery....better find the cause before the fix....my .02

Thanks for the solder idea Pianotuna .Just took some time and a really good soldering gun with a propane torch.

You'll see battery post melts like that on golf carts when the nut is not tighten down enough, or the battery cable is inferior, or compromised.

Yes, a golf cart motor draws a lot of amps (200 plus). Nothing on a RV other then an inverter draws huge amounts of amps, unless it was a combinations of many things running at the same time.

12 volt fan motors can draw steady amps enough to melt lead, especially if the dumbass(me) didn't get it tight enough.
At only 7 amps, I find it hard to agree, especially with the lack of damage to anything else.

Not even remotely likely, unless it shorted out.

I doubt that, there aren't any cables running under the axle housing.

OK, no response. If this is from a big draw you need a fuse. If you already have a fuse, you need a smaller one.

I have no inverter. I'd say this happened when I took it over to get tires, it was cold day so I ran the furnace. So I think the fan motor running the whole time caused the big draw.
I would look under where the jacks were placed for a damaged wire.
When you find the damage ask the tire shop to reimburse you for the new battery and repairing the wire.

Looks like you're drawing a lot of current. Got big inverter?
