Harbor Freight Mexcharger Question
Prior to going on a recent dry camping trip, I tested my new Mexicowanderer HF Charger. 2/10/55 or whatever it is. If I understand it, for regular charging, it should be set at 10 amps and Start, wh...

18 amps out of a 10 amp charger for that kind of money is tough to beat.
Here's a suggestion for charging by generator:
Use your "smart" high power charger long enough until it goes stupid and cannot finish charging the batteries to a level above 14 volts. Toss the smart charger in the loony bin until next time, connect the HF charger on Manual 10 amps NOTE THE TIME OF DAY. Continue to charge the battery at the 10 amp setting (the amperage will have dropped way back by then - it's natural ans expected)
When the voltage reaches 14.8, NOTE THE TIME. How many hours or minutes did it take?
Buy a 120 volt cutoff timer or a wind up alarm timer. The next time you need to boondock generator charge, it will be a lot easier when you have an idea of how long the finish charge is going to take.
AGAIN!
Charger manufacturers can get SUED if they insist their charge regimen is "correct" and batteries boil dry. But batteries that sulfate way too soon are darned near impossible to prove that the manufacturer used the wrong charge algorithm. Got it? THEY UNDERCHARGE WAY WAY WAY Undercharge on purpose.
Show me a SMART charger that is applied 30 cycles, and battery electrolyte density is correct. Good freakin' luck.
