Those of us with Cars built in 21st century have AGM batteries and battery senors. They don't like surges or being over charged.

I returned a HF charger because it would not work on a dead battery. I read the manual before the return... it said it would not click on if the charger does not detect voltage.

I'm going to have to hit up a bunch of garage sales this spring looking for freakin pre-ban battery chargers.

Surprisingly, 6V battery chargers seem to be declining in popularity. I only have one working charger that will handle 6V batteries (a NOCO), but it has all that automatic stuff.

I hear you OP. They all suck for just about everything. And, if the battery is a bit old and doesn't take a charge, good luck shocking it into shape.
Personally, I would just buy a lab DC power supply where you can set the amps and voltage |

Connect it in parallel with another battery, it'll start charging the dead one. After a couple hours, disconnect the good battery and it should continue to charge. Quote HistoryQuoted:

Not just Harbor Freight. I have an Exide one and if the battery is too low I "jump start" the charger with a 9V battery and a lead while it is still connected to the dead battery. Once it clicks on it will stay on and charge normally. Quote HistoryQuoted:

This right here. You can also use the same system for electrolytic rust removal. Quote HistoryQuoted:

With the smart chargers, you have to trick them into turning on for electrolysis as well; the old manual chargers were a lot easier.

I have several types and usually use my smart chargers if at all possible but I still keep my old carry handle wheeled AC Delco 1000 CCA that you can pretty much set up any way you want at 6 and 12 v and set the max charge amps. It's old but it's not getting tossed even though I have a portable 1000 CCA jump pack that is easier to use.

See this jewel right here?
I used one of these in School (and they were surplus THEN) when learning to repair 8 tracks, it worked then and it still works today to charge batteries. (it doesn't like Li's or maybe Li's don't like it, but IDGAF. let them runaway and bulge out, I don't work on many 737's) You can crank it up to wake up marginal batteries, turn it down, you're in charge. I love it so much, I've replaced it when he old one failed (leads were shorted together over a holiday weekend, smoked it). The "new" one says "Physics Department " on it! E Bay can be your friend, at times. |

Seems the trend is to make items that are people proof with the added benefit being reduced customer service calls dealing with simple stuff that can be found in the instruction manual. Everything is not for everyone. Made for the lowest common denominator; the same people who put contraceptive jelly on their toast and wonder how they got pregnant

The auto chargers don't work for shit in the cold either. Edit - correction, I have the 250a farm and ranch. Has an auto mode and brute force mode. The auto mode usually does jack shit, but put 250a on it for a few minutes and it'll work. |

Those older chargers are usually pretty easy to repair. It's basically a transformer and rectifier, either of which can be replaced with a generic equivalent.
I've had an old 6/12v charger for years and it still works well, but I'd try fixing it before buying a new one. |

My dad bought a Harbor Freight buzz box.
A year later it was dead. The Schumacher "ship and shore" buzz box I bought him for his trolling batteries in the 1990s still works. My neighbor has had a Harbor Freight computerized charger for about ten years. Its works, but it's so 'automatic' that it won't charge unless you hook it up to a battery with halfway good voltage. No charging of dead batteries allowed. I had to teach him how to jump start it. But it seems to be working as intended, a decade after he bought it. |
