Drains out all of that nice and tasty H2SO4, along with all of those nasty electrons...

....so does a nail jammed into the side of a loose battery connector that can no longer be tightened with standard tools (vice-grips?)

Are you at all concerned about:

...automotive hose clamp (stainless steel?, zinc plated?, or ???) corroding over time? ...if the clamp separates in the middle, but is still attached to the battery, that you will have an unintended conductive path flapping around?

My project requires an isolated supply. I rigged a UPS and a car battery to act as a AC power supply.

I needed to make connections to a car battery and I only found hose clamps in my junk box. Thought I'd post the idea.

One needs to check and recheck any item that comes from China these days...and those Walmart car battery connectors do come from China.

A few years ago I used some Walmart battery connectors and was having heating and intermitent problems.

It turns out that the connectors had been cold cast on cables....just about as effective as using super glue.

Went back with a multimeter and checked their supply..every darn one was faulty.

When you buy a Chinese product, you are the the QA inspector.

Nah, when you buy cheap crap from any country, you're the QA inspector.

The quality of Apple computers (made in China) is as high as if they were made in the U.S., IMO. The Chinese will work to whatever level of quality you're willing to pay them for.

Overly simplistic, I'm afraid. See "Quality Fade".

Hi Spehro,

Hmm, so I see (...I read this:

. Definitely a problem, and presumably there's a non-negligible cost to preventing it. Still, Apple and others seem to be able to manage the issue and even long-term I don't imagine they're thinking of going elsewhere for their production needs.

Thanks for the "heads up,"
