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.
.

If no balls float in any cell, the cell is short-

ed. This means your battery is beyond the point
of being properly recharged or reconditioned-
desulphated. Dispose of the battery.

If each cell floats three () or more balls (or 1250
on gauge-type), your battery can be desulphated-
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. 9) over-
night for a minimum of 12 hours before testing
with a digital voltmeter only.
