Re: Charging time and charger output

I don't see a conflict here. From Noco's website their 3.6 amp charger will take 17.5 hours to fully charge a 100 AH 12v battery @ 50% DOD. Their 7.2 amp charger takes 12.5 hours. The charger with twice the output only reduces the charging time by .707 times 17.5 hours to ~ 12.5 hours (.707 is the inverse of the square root of two). So Noco is agreeing with you by saying there is a practical limit to increasing charger output. I'm just trying to quantify that limit. Thanks. Steve S.
