Your alternator will mantain a proper charge on your battery. An alternator is not a battery charger by any means, unless you can turn off all power consumer with the engine running, it's not going to charge the battery at a fast enough rate nor will it likely to reach full capacity.
I don't know the exact number, but there is probably 140-180 amp draw with all electronic consumers running. At that level of draw, all your alternator can do is supply power to the consumers.
