[QUOTE="Rruuff Day, post: 146077, member: 2217"] I'm not familiar with the "7200" but most maintainers are not really designed to bring a battery back from total discharge (At least not in much of a hurry).The math is quite easy.... Battery charger amperage is the charge rate in Amp hours (Ah).... Thus a 2 amp charge is charging at 2 amps per hour. A vehicle battery size can be anywhere from 45 Ah and up to over 100 Ah. (not to be confused with CA or CCA ratings) so say 100 divided by 2 equals 50 hours of charge with a 2 amp charger from dead to full (assuming the battery is in a condition to accept the charge. A lot of maintainers note in the fine print directions (yes... there were directions that came with your maintainers....lol...) that they are not really designed to charge a dead battery. [/QUOTE]
