It all depends on the age and condition of your existing battery. My battery is already 5 yrs. running and observed alternator input to be on the range of 13.4 to 13.7 V without revving. If I charge it with a 12 ampere battery charger for 1.5 hrs. I noticed the alternator charging already reaching 14.0V also without revving.
