Re: Which charges more efficiently? Fast Charge or Trickle Charge??
If you're charging a nearly full bank and not using more than 4 amps at the time, I would think the difference would be negligible.
If you're charging a discharged bank that will accept more than 4 amps, I'd have to say the larger charger, which will run fewer hours. For that matter, I don't think a 4 amp charger would ever properly recharge a deeply discharged 500 Ahr bank, especially if the "trickle" charger only does so in float voltage.
