This is the problem with mixing batteries. Some AGMs can handle equalization while others will just run away; all bad. I would suggest removing the connections to the ones that CAN be equalized (make sure the other batteries are fully charged) and equalize them with a separate battery charger as that will allow you to leave the settings alone on your charger or inverter/charger if you have one. Once equalized, disconnect the external battery charger and reconnect those batteries. This is why I caution most not to equalize any AGM until you read your manufacturers manuals, considering the average boater's electrical/electronic skills.
