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.
.
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.
If each cell floats three () or more balls (or 1250 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 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:
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. 9) overnight for a mini-
mum of 12 hours before testing with a digital voltmeter only.
