Re: Upgrading to an Fi soon, should I buy a new alternator first or a battery?
You are going to need a 100+ amp alt. Once you account for the car's need of alt power your 80 to 100 amp alt is going to be more like a ~40-50 amp alt. Just saying there are 2 ways to kill your battery/batteries overcharge them at too high of voltage or undercharge them all the time. Leave a battery at the 80% charge mark for too long that 80% will become your new 100% and go down hill from there unless you get an agm charger that desulfates. As far as i know there isn't a company that will cover those two conditions under warranty.
