Battery Charger Heating Up?

Why would my battery charger heat up especially near the clamps?
Are they repairable or not? thx

When connecting your alligator clamps give them a bit of a wiggle to scrape away any corrosion so they make better contact with the battery posts. Any resistance from corrosion or not enough metal to metal contact will cause heat to be formed. The more amperage you charge at the worse this can be.

Warm would be normal. Do they get excessively hot?

If the wire gauge is too thin the amperage draw can cause them to get hot. As Joe said slightly warm is OK.

many cheap jumper cables will catch fire because they use 14 gauge or less wire size.

YES The wires are worn and frayed (OF COURSE!!) Duh!

I have one ( that overheats) that is old and frayed. My bad. Replacements in the works. Another just not having good readings on my volt meter. So I was asking (as uncleanly mentioned) if any have been repaired with any luck?
Thanks again!

Again what gauge is the wire? If the gauge is 10 or better then yes it might be worth getting new clamps. Assuming the insulation is good. But is it worth the cost vs a new set? You'll need to compare cost.
