BatteryMINDer 12612A - Manual (Page 8)

Display Operating Condition
Red Solid Light The red indicator lights to show that there is
AC power going into the unit.
Green Solid Light When the unit is attached to your battery, the
green solid light lets you know that the unit is
charging your battery.
Green Blinking Light The green blinking light lets you know that it
is desulphating your battery. If there is a lot of
sulphate in your battery, it cannot accept full
charge, and the BatteryMINDer does not
automatically start desulphating. The voltage
in the
battery has to go up to 14 volts in order for
the unit to automatically start desulphating.
Connecting and Maintaining Multiple Batteries
Before you start using your BatteryMINDer, check how your batteries are connected and decide how you are
going to connect the batteries to the BatteryMINDer.
If the batteries are connected in your diesel truck, golf cart, RV or airplane in series, you have to use a series
connection to the BatteryMINDer.
If your batteries are disconnected or removed from your vehicle, you may use a series or a parallel connection
depending on the model of the BatteryMINDer and the voltage of the batteries.
Parallel-connected with a 12 Volt 1 Amp BatteryMINDer
Batteries of the same type and same size only (engine starting, deep cycle, sealed, gelled, AGM, maintenance-
free) can be charged at the same time in parallel (+ to +, - to -).
When you connect the batteries in parallel, you are keeping the total voltage the same. For example, if you
connect two 12 volt batteries in parallel, the voltage of the combination is 12 volts.
When you connect multiple batteries in parallel, connect the + of the first battery to the + of the second battery.
Then connect the - of the first battery to the - of the second battery. The + of the first battery and the - of the
first battery connect to the BatteryMINDer if possible; otherwise, connect to the accessible battery.
