Q. Can I use the charger as a power supply?
A. Projecta automatic chargers are designed to only supply power to the battery clips when they are correctly
connected to a battery, this is to prevent sparks or damage to the charger or battery if connected incorrectly by
mistake. This safety feature prevents the charger from being used as a 'Power Supply'. No Voltage will be
present at the clips.
Q. In maintenance mode why does the current go high then low again?
A. While in maintenance mode it is normal for the current to go high and then low. The charger is maintaining the
battery voltage between the Cut-In and Cut-Out voltages. The pulses of power are topping up the battery to
maintain it fully charged.
