You are doing the wrong calculations - power consumption isn't measured in amps and all batteries and alternators have limits on to how much time they can produce their maximum output. Car batteries are only designed for high output over short periods of time - it's the same with alternators. If you are going to need a high output electrical source in your car you may not only have to uprate the battery but also the alternator to match. Battery output is measured in amp/hours. Also remember the ratings stated on batteries are for when it is new

See link below for an explanation.
