THE EVOLUTIONARY CHAIN OF
BATTERY TESTING
TECHNOLOGIES
1. First Generation - Physical Load Voltage
Tester
2. Second Generation - Electronic Battery
Testers/ Simulated Load Voltage
3. Third Generation – Dynamic Load
Voltage Tester
THE 1ST GENERATION:
PHYSICAL LOAD VOLTAGE TESTER
BCI Automotive Battery Test Load
Procedure
1. Connect the voltmeter and load test
leads to the battery terminals. Be sure
that the load switch test is in the “OFF”
position.
2. Apply a load test equal to ½ of the CCA
rating of the battery at 0oF (-17.8oC) for
15 seconds.

3. Remove Load.

specified, replace the battery.
PROBLEMS WITH 1ST
GENERATION TESTERS
• Battery must be at least 75% charged (12.45V).
If not, battery must be charged manually
(battery charger).
• Time consuming.
• Imprecise equipment can give false results.
• Too many tools.
• Has to “rest” (cool off) between tests.
• Technician has to know and follow the “recipe” to
perform test.
• Puts a physical load on the battery, with risk of
shortening its life.
THE 2ND GENERATION:
SIMULATED LOAD VOLTAGE (SLV)
TESTING TECHNOLOGIES
Based on the BCI load test, this is today’s most
popular type of automotive battery testing.
The two major technologies used are:
1. Conductance testing
2. Micro-load testing
MICRO LOAD TECHNOLOGY
EXPLAINED
1. Small load is applied to battery, which drops
initial voltage
2. Looks at battery voltage recovery
3. Small load is applied a 2nd time to battery,
which drops voltage again
4. Final look at battery recovery leads to
determination of battery status
Note: Some testers perform a 3rd Micro Load test.
CONDUCTANCE TESTING
EXPLAINED
Conductance is a measurement of the battery's ability
to produce current. It is a measure of the plate surface
available in the battery, which determines how much
power the battery can supply.
1.The tester creates a small signal that is sent
through the battery
2. Measures a portion of the AC current response.
3. Determines the battery condition.
POSITIVE ASPECTS OF 2ND
GENERATION BATTERY TESTERS
•
•
•
•
•
•
•
Easy to use
Work very well with fully charged batteries
Work very well with batteries out of vehicle
Fast
Avoid most drawbacks of first generation testers
Do not put physical load on batteries
Excellent tool to manage battery stock (battery
rotation)
PROBLEMS WITH 2ND GENERATION
BATTERY TESTERS
• Affected by all other loads applied on the
battery (Not recommended to test battery if still
connected to vehicle’s battery terminals/
cables)
• The greater the discharge, the less reliable
the test result - Will give “Charge and Retest”
test results on great majority of discharged
batteries
• Easily fooled by surface charges
AUTOMOTIVE BATTERY TESTING
The 4 Factors That Influence
Battery Test Results
1. Battery Temperature
2. Battery Size
3. Age/Condition
4. State Of Charge
Battery State of Charge
Initial Voltage
Percentage of
charge
12.66 Volts
100 %
12.45 Volts
75%
12.24 Volts
50%
12.06 Volts
25%
11.89 Volts
Discharged
All these factors have to be
measured to correctly
determine the battery status
“CHARGE AND RETEST”
Fact: All battery testers try to determine the battery condition by measuring the
internal resistance. Of the 4 factors determining internal resistance, the state of
charge resistance is the only parameter that can be influenced (by charge). It has
such a high influence when the battery is discharged that it must be nullified for an
accurate result.
1. High internal resistance
created by discharged
battery (light blue)
overwhelms other
conditions.
2. Test result = “Charge
& Retest”
The internal
resistance is
the sum of
these 4
conditions.
THE 3RD GENERATION:
DYNAMIC LOAD VOLTAGE TESTING
ELECTRO-PRO V14
ELECTRO-PRO V14: HISTORY
• The Electro-Pro V14 is a result of years of
development & field testing by battery
testing experts, battery manufacturers and
governmental R&D laboratories.
DYNAMIC LOAD VOLTAGE
TESTING EXPLAINED
The Electro-Pro uses high frequency scanning to
measure and perform digital signal processing on
voltage, charge acceptance and battery condition
simultaneously while the engine is running or the battery
is charging.
This enables it to determine accurately the condition of all
batteries including completely discharged batteries.
3RD GENERATION:
TECHNOLOGY EXPLAINED
•
•
•
•
•
•
Pulsed impedance testing uses a very high frequency load
pulse on a battery while the engine is running or the battery is
charging to directly measure its internal resistance.
The frequency is high enough that any parasitic loads that may
be draining the battery do not influence its readings.
The high frequency and the digital signal processing is
advanced enough that the readings it makes are not even
affected by an alternator charging a battery.
Uses the battery’s internal resistance and other parameters to
calculate its condition.
Can accurately assess the condition of a completely discharged
battery in a test that takes up to 4 minutes. With a partially
discharged battery, the test is considerably shorter (30 sec.)
All tests yield a usable test result. No results of “Charge &
Retest”.
4) When tester has gathered enough
information from the charge acceptance
versus battery condition graph, it makes
an extremely accurate projection of what
the battery’s condition will be when fully
charged, using proprietary algorithms.
1) Through the
amps probe,
the tester
monitors the
charge
acceptance.
2) Tester begins
to determine
what the
battery’s
condition will be
when fully
charged (at least
9.6V).
DYNAMIC LOAD VOLTAGE
TESTING EXPLAINED
3) Tester
monitors charge
volts.
3 TESTS IN 1 - STARTING/BATTERY
PARASITIC AMPS DRAIN
IMPORTANT: Tests not only the battery
condition but also the two most common
sources of problems for a discharged or
defective battery:
• Charging system (Alternator/Regulator)
• Parasitic Drain
