BatteryMINDer 12612A - Manual (Page 9)

Connect each battery to one another using 18 gauge
(lamp cord type) insulated wire. Strip at the points where
you wish it to be in electrical contact with the posts of
each battery, then use ring or clip connectors. VDC
Electronics, Inc. does not provide any type of wire
harness to accomplish this, due to the many variations in
size and terminal configuration.
Always desulphate each battery separately for 2-3 days if they are connected in parallel. Otherwise, they will
not be equally desulphated.
Series-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 series (- to +).
When you connect the batteries in series, each battery is adding to the total voltage. For example, if you
connect two 6 volt batteries in series, the voltage of the combination is 12 volts. If you connected them in
parallel, the voltage would be 6 volts, and you would have to use the 6 volt BatteryMINDer.
When you connect multiple batteries in series, connect the + of the first battery to the - of the second one. To
add more than two batteries, connect the + of the second battery to the - of the third battery. The - of the first
battery and the + of the last battery connect to the BatteryMINDer if possible.

Troubleshooting
Problem Solution
Red light is not on If the red Indicator light does not come on when you plug the
BatteryMINDer into an AC outlet, check that the outlet is
switched on. If the light still does not come on, the
BatteryMINDer might have
failed.
Green light is not on If the solid green indicator light does not come on, you have not
made a proper connection to the battery. The green light lights
up even before you have plugged the unit into an electrical
outlet.
