The BatteryMINDer charges and maintains any size 12 volt car, boat, RV, motorcycle battery without ever
overcharging.

The BatteryMINDer comes complete with a molded ring terminal assembly and insulated battery clips. The 18­gauge lamp wire for connecting multiple batteries is not provided in the package.

General
The BatteryMINDer Charger/Maintainer/Conditioner Model 12612A 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 20Ah
maximum, or series connected for 6 volt 20Ah maximum) 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 Your Battery

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 [e-mail] or call our toll-free
technical support line (800-379-5579 ET). Be certain to leave your phone number with the area code, time zone
and the best time to call.

Testing a Manifold-type 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 1/4" 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.

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-free, Gelled-type 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.
