**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
desulfated or does not qualify for desulfation.
3.
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.
Properly dispose of the battery.
If each cell floats two (2) or more balls (or 1190
on gauge-type), your battery can be desulfated-
reconditioned.
4.
Always rinse the tester with fresh water after
every use. Failure to do so will cause false readings.
Testing a Sealed, AGM or Gelled-type 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:
1.
Recharge the battery with the BatteryMINDer
to ensure it is as completely charged as possible,
before you determine its condition. Allow battery to
“rest” (see pg. 13) for a minimum of 12 hours before
testing with a digital voltmeter only.
Failure to test a “rested” (see pg. 13) battery will
cause false readings.
