Generally it is said that a lead-acid battery charging current is 0.1C during float charging. so if a battery capacity is 75AH at 12V it require 7.5A DC voltage at 13.8VDC.
But i think that current will be determined by the difference of voltage between charger and battery. The more voltage difference drains more current to battery. so current is not a fixed value during charging.
so, my quary is what is the significance of 0.1C? and what is the minimum charging current for a 12V 75AH lead-acid battery.
Thanks.
