Alternator charges the battery at a regulated 5 A/h. It charges at a much lower rate than specified on the batteries usually 1/10 of their capacity. This is because charging at full pin would overheat the battery, generate high levels of hydrogen gas and dramatically reduce the longevity of the battery.

61 A/h battery at 5A/h charge rate would fully charge from dead in 12.2hours. The alternator is capable of generating 1.96 Kw. If it did all day both the alternator and regulator would probably self destruct. The battery only purpose is to start the car and run accessories when the engine is not running. Once started the alternator runs the whole show.
