Will Prowse warns us about the Chinese products or sub standards. I have run into this on products I purchase on Amazon and am fed up with it ! Does anyone know if or where we can buy quality electrical products ??

I buy tinned wire from marine suppliers. The Chinese approach is look at something ,copy it but try to use cheaper materials and design then sell it just under the previous price .
Have you noticed how your feet have been growing in chinese shoe terms over the years ? Each size gets a bit smaller each year.

The terminal end in that picture is a TERRIBLE cheapo acid or moisture environment fail waiting to happen...

Dang, really? They advertise as heavily tinned copper. Isn't that what you want?
 
Oh, you must be talking about the crimp I just noticed.

The end of the terminal is open... so, unless the wire is tinned, acid or salt can degrade the wire.

I spent some bucks on 4/0 from them. I'll have to examine that when I get home. Another day, another pile of dollars wasted on crap...

As long as not near acid or saltwater, they will be fine.
Maybe seal the ends with grease?

If they look like that, should I just re heat shrink right over them? They are inside and will never be near saltwater or acid, unless the batteries explode.
 
For reference, these are what proper crimps should look like (before shrink tubing). This little cable (demoing the difference between the FTZ Heavy Duty lug on the left side and FTZ Starter Lug on the right side of the first pic) is about 6 years old and our wholesale manager, who is well over 300 lbs, can still hang off it and do pull-ups... not that anyone will be doing that, but the rule of thumb in heavy-gauge wiring is that if you can't apply at least 100lbs of pull to your crimps without them moving, you don't have good crimps.
Note the proper 4-sided crimp (with an FTZ bench-mount Correct-Crimp) and the closed-end lugs (it's all tinned marine wire anyway, but still). Never settle for crap.
