i know there are plenty of people who use kinetik with many different brands of highoutput alts and have used them both under the hood for YEARS without an issue. 14.3 is THE standard charge voltage for agm cells btw. "Lead acid batteries have different charging requirements based on their specific design. Flooded and maintenance free batteries require a higher voltage per cell than do sealed valve regulated types such as AGM and gel-cell batteries. Overcharging will reduce the life of any battery as sealed valve regulated batteries are especially sensitive to high charging voltages and overcharging. Overcharging an AGM or gel-cell battery will cause permanent damage. The proper charging level can be selected by means of a battery type switch on the front panel." "CAUTION: Use the correct battery type at all times. Do not charge AGM & Gel-cell batteries in the
