The thing is, for every hit to the battery that isn't immediately drawn from the alternator, you alternator will have to work just as hard to charge it up again. Having two batteries isn't going to magically make electricity come from nowhere. Your car will still use the same amount of electricity, and it will still have to come out of your alternator. It might just save the peak loads from hitting your alternator so hard.
