    Question 4 Amp Charger

    I discovered a 4 amp charger in my garage the other day or yes dusted it off. Does the charger charge 4 amps per hour or how does it work? I have recently aquired a 102 amp high cycle battery. Would one assume then that this battery would take 102\4 = hours to charge??

    Yep, at least! Normally, a while longer because as the battery voltage rises, the amperage from the battery charger falls. But be careful of trying to use it as a permanent charger, it will eventually overcharge the battery because it will never 'switch off" completely. A regulated battery charger does just this, measuring the battery voltage and adjusting the charge rate accordingly, from max to a nominal trickle to charge to just keep the battery topped up in a standby mode.

    Look at the back of the charger its usely half of that in front dont be fooled , then you can do your maths. the charge time depends of how many amps did you draw against time.
