It's easier to blame the battery brand and react to fads in Dyson shaped smart battery chargers. Ribbed fluorescent plastic, magic encoded flashing lights and "Press Me" buttons. Remember those ridiculous sound-effect "guns" a person could mount atop their dashboard with selector noises and flashing muzzle? Take your pick to emulsify the car that cut you off - phasor beam, photon torpedo, or desruptor...
Beefy battery cables. Looks like 6-gage. Cut it in two and the conductor is 11-1/2 gauge. Cadmium plated 1010 steel clamps.
A USA company that makes excellent quality chargers is Associated Industries. Sort of like the Lifeline or Rolls & Surrette of manual battery chargers. When I made my 160-amp 3-volt charger for the cells I gutted a blown-up Solar wheeled charger. Used those monster plating rectifiers and 10 pounds of 3/16" copper plate. A 76 lb transformer (Lockheed auction) and a 30-amp twist-lock plug. I got fancy and used red and black 2/0 welding cable and Associated 800 amp clamps. I purchased a surplus Simpson 2.0 - 3.0 expanded scale voltmeter and had to make the handle on the charger taller. 6" wheels and 5/16" axle from Surplus Sales of Nebraska. I could probably sell it in a hot 10 seconds for a thousand dollars. A 20 amp ON/ON switch taps a 50% H1 H2 transformer inlet.
With a bit of curiosity followed by a pervasive push to finish projects the world is open to whatever a person wishes to do.
Bottom line? The pushbutton crowd spends 10 times as much effort as I do. But trying to explain it is fruitless.
