Considering that the harbor freight battery maintainer costs $10 and is a total piece of shit that'll last a year at best, this is still a good deal on a microprocessor controlled charger/maintainer that also appears to support AGM batteries. Worst case, take it home, try it and if it's a POS just take it back. Walmart's return policy is pretty bulletproof.
I read the full text of every review on the wallyworld product page and saw nothing that seriously suggested that.

Here's some important points I can offer after using this charger successfully, and reading the manual:
I bought this yesterday and charged my Elantra's battery overnight from under 60% to full.
You know the first thing I did? I clipped it on, plugged it in, and saw the F01 fault code... BUT... because I'm not an idiot, I ALSO noticed the green battery-size-indicator light on the unit defaults to 6V... and the only button the unit has functions as the 6V/12V toggle. And I toggled it. And I did this without checking the manual since... duh.
But unlike "internet commenters", I did eventually read the manual.
My battery was apparently under 60% when I started, so the readout initially displayed "Lo" just as described in the manual.
For the curious, this took about 12 hours for my RC=120min Elantra battery.

Firstly, I cannot claim that I knew any better before reading the manual, either!! To summarize what I gleaned from some research to satisfy my own curiosity: the battery, esp while charging, is prone to produce hydrogen gas as a product of the chemical reactions involved. Hydrogen is potentially explosive and at least flammable, so if you are incredibly unlucky and somehow a spark or electrical arc happens, that's bad news!
The reason you would move the negative clamp to the chassis/block is simply to get the clamps farther away from each other, so as to reduce arc potential.
The reason you *can* clamp to the chassis/block is because the negative post of the battery should also be electrically connected to ("grounded to") it. Hope that helps, and that I am not too far off reality!

Exactly, and exactly!

Approximating Charge Time:
I have owned and returned 4 of this same model charger. All have suffered the same multitude of problems described in all the negative reviews posted by others, which CAN NOT BE OVERCOME BY READING THE INSTRUCTIONS. I spoke with a tech that told me there was a firmware problem (as I already stated) that causes this charger to choke... thus, all the returns.
For those considering buying this piece of garbage, please read the reviews by others first before throwing your money away. (Sort the reviews from lowest to highest rating and take note). If you already own one, I hope it works well for you and you dont become one of the others that threw out their money.
I now use Deltran Battery Tenders on all my vehicles stored for extended periods of time with ZERO problems. If I have a discharged battery that needs to be recharged, I use a large industrial 5-50 amp charger to desulfate the plates and get the job done correctly.

This charger is not supposed to charge if it detects current being drawn.
Most vehicles made in last 20 years drawn current from the radio or computer / security.
So charger should throw a code if the battery is connected.
This also means you must connect the clamps to the terminals unless you only disconnected the positive .
I suspect this being the reason for some of the bad reviews.

If you try to charge dead car battery, of course it will be throwing different error codes due to excessive current consumption by dead battery.
