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 desulfated or does not
qualify for desulfation.
C.
If no balls float in any cell, the cell is shorted. This means your battery
is beyond the point of being properly recharged or reconditioned-
desulfated. Dispose of the battery.
D.
If each cell floats three (3) or more balls (or 1250 on gauge-type), your
battery can be reconditioned-desulfated.
E.
Always rinse the tester with fresh water after every use. Failure to do
so will cause false readings.
CHARGING A SEALED, AGM OR FLOODED (WET-CELL)
LEAD ACID BATTERY
These batteries have no filler caps or manifold-type covers. Because you
cannot gain access to the interior of your battery you cannot test it with a
hydrometer.
USE A DIGITAL VOLTMETER ONLY
A.
Recharge the battery with the BatteryMINDer to ensure it is as
completely charged as possible, before you determine its condition.
Allow battery to “
REST
” overnight before checking the open circuit
voltage with a digital voltmeter only. Failure to check a “
RESTED
”
battery will cause false readings. Be certain to read and understand
all safety related instructions (pages 3 - 7) before proceeding further.
B.
Measure battery’s voltage, without any load attached. If the voltage is
less than 12.6 volts (Typically 75% of charge) the battery may be too
heavily sulfated to be fully recoverable. If voltage is 12.6V or higher
recovery can be expected, given sufficient time.
C.
Connect the BatteryMINDer to the battery
D.
Charge battery to its maximum level. Allow battery to remain for a minimum
of 72 hours before retesting. If improvement is seen, continue until
battery voltage reaches full capacity level or no further increase is seen.
Note: Do not expect to completely dissolve sulfate in a day. Long
established sulfate will require a longer period to be fully dissolved.
Be patient and you will rewarded with a “sulfate-free” battery. If not
seriously damaged by sulfate, battery has a very good chance of
meeting 85% Cap (Airworthy) Test.
