technology to determine battery condition, only
with a more sophisticated algorithm pro-
grammed to its internal microprocessor. This
subtle improvement allows the tester to more
testing batteries, charging systems, and starter circuits 25accurately diagnose problems with all three
common battery types: flooded (liquid elec-
trolyte), gel-cells, and AGMs. The photo
sequence shows the battery test procedure.
If conditions are outside of the parameters—
such as low temperature or deeply discharged—
required for an accurate test, one of several screen
tests may appear next:- Temperature compensation test: The
inTELLECT EXP-1000 may ask you to
measure the battery’s temperature with the
unit’s infrared temperature sensor if the
unit detects that the temperature may
make a difference in the result. It will
prompt you to place the sensor within 2
inches (50 mm) of either the top or side of
the battery. After the temperature reading
is displayed, hit the“Next” key. The
instrument will capture the temperature
data and recalculate its findings. - Deep scan test: If temperature compensa-
tion doesn’t allow the in TELLECT EXP-
1000 to complete its calculations, the unit
will jump to a deep scan test to further
analyze the battery. It may ask you to run a
Then you enter a specific rating value. In the case of CCA
or MCA, the entry range is from 100 to 3,000 amps. This
represents more than enough capacity to deal with even
the largest marine battery in common use, the 8D, which
has a CCA rating between about 1,200 and 1,600
amps, depending on the make and model. After entering
the required data, press “Next” and the test begins.
The results of the battery condition test: Good Battery. At
12.48 V, the battery is not fully charged, but because its
indicated capacity of 543 CCA is over its rated capacity,
the battery is still in good condition.
The SOC screen presents battery voltage from photo 6
in an easily comprehended graphic format. In this case, it
tells you that 12.48 V is 75% SOC.567
