Alright mate, Different sized batteries will draw more or less current when charging depending on their capacity (room to store current) and state of charge (how much is already in there), it depends on the charger, some chargers will only charge at a maximum of say 2 Amps, then it is the time the battery is charged for that gets longer, for example, a 17 A/hr battery will take 4 ish hours to charge at 4 Amps from empty, but 8 hours at 2 Amps. So big batteries will generally draw more current when charging if the charger can give it. Does that help?! Quote Link to post Share on other sites
