Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.
If there is a dead or weak cell, normal charging voltage can''t be achieved on a battery with a bad cell. The alternator will overcharge the remaining cells and boil the electrolyte in the other cells. At the other extreme, a battery that is sulfated due to being undercharged or not seeing constant use will maintain normal charging voltages.
