The BatteryMINDer charges and maintains any size 12 volt car, boat, RV, motorcycle battery without ever overcharging.
Battery Voltage vs. Charge Percentage
The BatteryMINDer comes complete with a molded ring terminal assembly and
insulated battery clips. The 18-gauge lamp wire for connecting multiple batteries
is not provided in the package.
General
The BatteryMINDer Charger/Maintainer/Conditioner Model 12112 is designed to
charge and maintain your battery without ever overcharging it. The unit utilizes
patented technology to produce a wide range of high frequency pulses (RFP)
designed to dissolve both old and newly formed sulphate. The pulses free the battery from sulphate and extend the life of your battery.
The 12 Volt - 1 Amp BatteryMINDer allows you to charge up to 4 batteries (parallel
connected for 12 volt, or series connected for 6 volt) at a time. The batteries must
be the same type (starter, deep cycle, sealed gel, AGM, etc.). Also, the battery
voltage (6 volt, 12 volt), the resting voltage (minimum of 11 volts for a 12 volt battery and 5.5 volts for a 6 volt battery), Amp and the condition of the batteries must
be the same if you charge more than one battery at the same time. See page 7
for more information on parallel and series connections.
Use the BatteryMINDer on your battery at all times (winter, summer, spring or fall)
when your battery is not used for 4 days or more. This will prevent new sulphation
from taking place and will lead to dramatically increased battery life and performance. Do not remove the BatteryMINDer from your battery unless you place the
battery back in service.
Failure to keep the BatteryMINDer connected to your battery at all times that the
battery is not in service will affect its performance claims.

Testing
It is extremely important that you determine the health of your battery before you
attempt to recharge and recondition it. If any of the cells are shorted (no reading
on a hydrometer tester), or the difference in charge level is greater than 0.50 SG
between any two cells (two ball difference if you use a ball-type hydrometer), your
battery cannot be properly recharged and reconditioned. Discard the battery in an
appropriate lawful manner.
The BatteryMINDer has no electrical output unless it is connected to a healthy battery. Testing the BatteryMINDer with a volt or an Amp meter without the unit being
connected across a good battery will result in a false reading. If you experience
any problems, or are not sure of how to properly use or connect your
BatteryMINDer, please e-mail our technical support at
techsupport@vdcelectr
379-5579 ET). Be certain to leave your phone number with the area code, time
zone and the best time to call.

Voltage Percentage
Testing a Manifold-ttype Lead Acid Battery
1. Carefully remove all 6 caps or both manifold-type covers from your battery (3
caps on a 6 volt battery).
2. Check the water/electrolyte level. If the level is low or has ever been below
top of plates, severe lead plate sulphation has taken place. Significant
recharge/reconditioning time is needed to restore those plates to a condition
where they can be expected to function normally.
3. Refill each cell with distilled water only to a level of ¼" minimum over the top
of the cell's plates.
4. Recharge the battery with the BatteryMINDer to ensure that it is slowly and
completely charged before you determine its condition.
5. If the BatteryMINDer does not start blinking within 72 hours, your battery may
be too far gone to be reconditioned. However, lightly touch the desulphation
1
2
button to set the unit in the maintenance/desulphation mode. The light will
blink continuously until it is disconnected from the battery.
6. Allow the battery to remain in the maintenance mode for a minimum of 72
hours before you test it for dead cells. Use a hot/cold calibrated hydrometer
tester for the most accurate results. If you see an increase in the Specific
Gravity (SG) indicating that there is an improvement in the battery's condition,
continue desulphating for an additional 72 hours and retest the battery.
Continue this process until the SG reading of the battery does not increase
anymore.
Testing with a Hot/Cold Calibrated Hydrometer Tester
Read the tester instructions carefully for most accurate readings.
1. When using the tester the first time or after a long period of non-use, fill the
tester with the battery fluid and let it sit for 1/2 hour or longer. This will soak
the balls in order to give you more accurate readings. Failure to do so will
give you false readings indicating a battery that may not be in as good a
condition as you may have thought.
2. After inserting the tester in a cell, gently tap the tester several times against
the inside wall of each cell to dislodge air bubbles that will cause more balls
to float than should. Failure to do so will yield false readings that indicate a
battery that is not fully desulphated or does not qualify for desulphation.
3. If no balls float in any cell, the cell is considered shorted. This means that
your battery is beyond the point of being properly recharged or reconditioned.
4. Dispose of the battery.
5. If each cell floats two or more balls (or 1260 on gauge-type), your battery can
be reconditioned.
6. Always rinse the tester with fresh water after every use. Failure to do so will
cause false readings.
7. Store the tester in the holder to prevent breakage.
Testing a Sealed, Maintenance-ffree, Gelled-ttype Lead Acid Battery
These batteries have no filler caps or manifold-type covers. If you cannot gain
access to the interior of your battery, because it is sealed, you cannot test it with a
hydrometer.
1. Test the battery with a voltmeter. If the voltage is less than 11 volts, charge
the battery overnight with a regular charger or with the BatteryMINDer.
2. Let the battery rest for minimum of 8 hours, which means that you do not use
or charge the battery for 8 hours.
3. Test the battery with a voltmeter. If the voltage is less than 12.2 volts (25%
charge), the battery might have too much sulphation in it to reach full charge.
4. Connect the BatteryMINDer to the battery.
5. Lightly touch the Desulphation button to start the maintenance/desulphation
mode right away.
6. Let the BatteryMINDer desulphate the battery at least a week.
7. Test the battery again with a voltmeter.

Installing the BatteryMINDer
Before you connect the BatteryMINDer to your battery, test the battery for any
shorted cells and check the voltage in the battery. The battery has to have a minimum resting voltage of 11 volts before the unit will turn on. Resting voltage
means that the battery has not been charged or discharged within 8 hours minimum. If you test a battery that has not rested for at least 8 hours, you will get
incorrect, inaccurate readings.
1. Test your battery first before you connect it to the BatteryMINDer. See page 2
for more information on testing the battery. See page 5 for more information
about installing the BatteryMINDer inside or outside of the equipment.
2. Check the voltage in your battery. If the resting voltage is less than 11 volts,
use a regular charger to charge the battery to full voltage before connecting
the BatteryMINDer to it. The BatteryMINDer does not turn on if the voltage is
lower than 11 volts.
3. Plug the battery clip assembly supplied in the box into the mating plug at the
end of the BatteryMINDer's output cord, or attach the ring terminal assembly
to your battery's terminals (red to + and blue to -).
4. Attach the battery clips to the posts or terminal clamps of the battery (red to +
and black to -).
5. The green indicator lights when the proper connection is made. The green
light is powered by the battery and lights up even when the BatteryMINDer is
not plugged in an electrical outlet.
6. Plug the BatteryMINDer into an AC electrical outlet as soon as possible after
you have made the connection to the battery. Note: The unit will use the
power from your battery and drain the battery if you do not plug it into an
electrical outlet.
7. The red indicator lights to show that there is AC power going into the unit. If
the red light does not come on, check you outlet to make sure that it is
switched on. The red light stays on unless the outlet is switched off or the
BatteryMINDer has failed.
8. The BatteryMINDer charges your battery to full voltage first before it automatically goes into the maintenance/desulphation mode. The green light stays
solid during the charging mode.
9. The green indicator light starts blinking automatically after the BatteryMINDer
has charged the battery to full voltage and goes into the maintenance/desul
phation mode. 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).
10. If the green indicator does not start blinking within 24 hours, lightly touch the
Desulphation button to manually start the maintenance mode.
11. Leave the BatteryMINDer connected to your battery at all times when it is not
in actual use. You can never overdesulphate your battery.
See page 7 for more information about connecting multiple batteries.
