Simple 110V-12V car battery charger?
I'm exhausted and depressed after reading reviews on Amazon. "Multistage" chargers that have only 2 stages (sometimes 1). Bulk stage running at 16-17V 'cause some idiot imbedded a "desulfation" mode...

Any Smart charger's charge algorithm will be a compromise designed to safely undercharge any battery.
The marketer's are depending on that placating green light full charge indicator to sooth the masses, and making up new 'stages' of charging to impress those waffling on a purchase decision.
Reviews on Amazon by the seriously uninformed mean less than nothing.
If the charger has a maintenance/ float mode, it likely will eventually fully charge a battery if plugged in for long enough. But there better not be any load on the battery or you will find the flashing error code.
I got used to seeing my old Schumacher sc2500a flash the green light, drop to 13.2v, and yet the battery still required 5 amps to hold 13.2v. Fully charged, my buttocks. Other times it would blast right past the mid to high 14's up into the 16's at 15 amps while the battery fizzed like a just opened soft drink.
Screw Automatic smart chargers and the marketers thereof.
