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.
