Harbor Freight Tools that don't suck

Solar powered battery maintainer from Harbor Freight.... clamps were barely soldered and one wire came off as I was attempting to pin it out with a multimeter. So, I broke both wires off, tinned them, crimped them and soldered them back to the clamps properly.... at $9.99 on coupon.... Can it be okay?
I used one of those for years, intermittently on a seldom-used tractor. I think it will stay ahead of the self-discharge of a battery, but I doubt it's sufficient to maintain a modern car (or tractor?) that has an active alarm system or other continual draw. And I know it won't bring voltage up if it is already below 12.6, fully charged, when you attach it.

That high no-load voltage doesn't mean anything. Any load at all will pull the voltage back down to match the battery it is attached to.

After I didn't use the solar charger for months then found my neglected tractor had gotten down to 12.2 volts, I quit using the solar charger and went to a Batteryminder from Northern Tool. Those have an excellent reputation online. That charger is capable of bringing up a discharged battery (at 1.3 amps) and is claimed to shut off when not needed.

I've got 4 of those Battery Minders. One on the Corvette, on on my trolling motor battery, one on seldom used garden tractor, and a spare. I catch them when they go on sale for $19.99 at NT.

Sucks or not... I do not know.

I've had one for a few years. Tried to use it to charge a few things. One was an 8AH SLA that had a small current draw. It would charge, barely, but not enough to keep up with the draw. I'd charge the SLA from a standard charger, then put it in the system (tried different ones) and within 3-4 days it would be dead, then I'd take it out and put it back on the regular charge. Wash, rinse, repeat til I finally gave up.

Right now, it's used to power a small 12V relay to activate a circuit I only want on during daylight. Sort of the opposite of what a normal dusk to dawn photocell does. The rest of the circuit is powered by a 110VAC to 12VDC converter.

I used one of those solar battery chargers with a home brew regulator to maintain the charge on a backup generator battery. Worked great for a few months, then the solar collector failed. Replaced it with a different panel and it is still going.

FWIW, i saw a report that someone had left one of those (without a regulator) on a car for several months unattended and it caused the failure of the battery.

Oddly, the voltage under my shop LED lighting is showing over 19 volts with no load.

The one I bought definitely falls into the "sucks" category. Put one on a seldom-used ATV. Couple months go by, try to start the ATV, battery dead. No output at all from the maintainer. Took it apart, looked like a bad connection to the solar panel itself. The wires aren't soldered to the panel, they're held in place by some sort of snot. Peeled it off, cleaned up the connection. Neither the panel traces nor the cheap Chinese tinsel wire would accept solder. Replaced wires with real wire, used some glue to hold 'em to the panel.
Works now, sorta. Only get ~12.6v in bright sunlight with no load. Threw it out, picked up a couple Ray-O-Vac ones that were on closeout at Walmart for less than the HF one. ROV ones seem to work just fine.

Needed a garden tiller and found the perfect sized one on craigslist (Troybilt Bronco II). The 5 HP B&S engine was blown, but marched myself right down to HF and picked up the 6.5 HP engine for $99 with my discount coupon. It's true...ONE pull on the starter and she fired right up. All tilling I've done so far has been slightly above idle and that's more power that's really needed. Extremely pleased.

Need more? Bought the drywall panel hoist and concrete mixer & 4' x 8' utility trailer. All perfect for what I use them for.

I don't know if it's a good value, but the $80 16" x 30" Service Cart is super handy for me.

I don't have any space to actually work in the garage, so I load up the tools I need on the Service Cart and haul them to the driveway or back patio.

I wind up making several trips back into the garage to grab things and they all wind up on the cart. When I'm done, I can just roll the cart inside and put everything away without making another umpteen trips.
