MODE LEAD-ACID CHARGING PROGRAMS Settings are made by pressing the MODE-button. After about two seconds the charger activates the selected program. The selected program will be restarted next time the charger is connected. The table explains the different Charging Programs: Program Explanation NORMAL Normal battery program 14.4V/25A. Only for lead-acid batteries. RECOND Recond program 15.8V/1.5A Use Recond to return energy to empty WET and Ca/Ca batteries.
