Any ideas where I can find a pair of *quality* battery clips to attach
to my existing battery charger? Probably 12 gauge wire to the charger,
need oversized clips to attach to the battery lugs. I've about
exhausted the hardware/electrical outlets in this area.

Thanks...hk
Here's a start:

12ga on the battery side?

12 ga. at 10 feet is only good for about 15A....

The extension cord manufacturers show different results...

Think "Vise Grips", Herr Krause.

"Vise Grips" are the heavy duty all purpose battery clamps that even
you might be able to figure out how to operate.

10 feet of 12ga stranded copper will drop 0.59v at 15a.

When that is deducted from 120v it is fairly insignificant but it is
4.9% of your 12 volts.

Based on a 12AWG stranded wire resistance of 0.00159 ohms per foot, the
voltage drop would be 0.225 volts.

There maybe a few more 10ths volt drop depending on the integrity of the
clamp's connection to the battery.

It's really interesting that an expert welder, as Harry has claimed to
be, doesn't know where to look for quality electrical spring clamps.

Is there anything that Harry isn't an expert at?
I wonder, with all of those skills, how he has any time to post here
constantly.

You have to get back so double that ;-)

I used a calculator based on the table in the NEC. I know the AARL
table shows lower resistance. It has to do with the temperature.

Having done more jumps than I care to remember, all I know is pay for
the heaviest jumper cables you can find. Make sure the side-mount
clips are spring-tensioned and not the slide-on type.
But I don't get why anybody would care about charger clips.
Even the lightest, cheapest feeling clips have always worked fine for
me.
In fact, that's what's on my Sears charger, maybe a 50 buck model with
2 and 10 amp modes and a "start" mode.
I've started 2 cars with virtually dead batteries using that "start"
mode and those cheap clips. No problem at all.
Charges fine on the 2-amp mode with those cheap clips too.
Never used the 10-amp.
Supposed to be automatic, but I've always unplugged it after a day
charging a depleted car battery. Don't like that humming.

Yep, DC not AC. You are correct.

The current rating of an extension cord not only applies to the wire gauge
but the construction of the connectors.
