This entry level charger will charge most auto and marine starting batteries overnight. It should not be left connected to a battery for more than 48 hours. Two LED indicators show when the unit is powered and when the battery is fully charged. Not recommended for other than normal starting batteries. As a general rule, do not charge deep cycle batteries at amperage greater than 10% of the battery amp hours.
