let me ask you this- if your car battery was dead would you leave your vehicle running in the driveway for 45 minutes??
Yes I know we're talking about different styles of batteries
No ranting here, just easy math. Without you providing your variables such as battery type, amp hours of storage, starting state of charge, finishing state of charge and charging output of your charging device, there really isn't much to discuss. The majority of the folks, myself included, are using generalities and averages for examples. Maine Sail took more time than I did and provided a more complete answer based on his example. As you can see we both used the same math providing the same answers. Maybe you have unobtainum batteries and a 10,000 amp charger and 10 minutes is all you need.
