Chapter 1 Product Summary

1.1 Product Profile

BST-100 Battery Tester adopts currently the world's most advanced
conductance testing technology to easily, quickly and accurately measure the
actual cold cranking amps capability of the vehicle starting battery, healthy
state of the battery itself, and common fault of the vehicle starting system and
charging system, which can help maintenance personnel to find the problem
quickly and accurately, thus to achieve quick vehicle repair.

1. Test all automotive cranking lead acid battery, including ordinary lead acid
battery, AGM flat plate battery, AGM spiral battery, and Gel battery, etc.

2. Directly detect bad cell battery.

3. Polarity reverse connection protection, reverse connection will not damage

the tester or affect the vehicle and battery.

4. Directly test the battery with loss of electricity, no need to full charge before
testing.

5. Testing standards include currently the world's majority of battery
standards, CCA, BCI, CA, MCA, JIS, DIN, IEC, EN, SAE, GB.

6. Support multi-languages, customer can select different language package,
which includes: Chinese Simple, Chinese Traditional, English, Japanese,
Russian, Spanish, French, Italian, German, etc. Other languages can also
be customized according to user's need.

1.2 Product Function

Main functions of BST-100 battery tester include: battery test, cranking test,
charging test and other additional functions.

Battery test is mainly targeted to analyze the battery healthy status to
calculate the actual cold cranking capability of the battery and the aging extent,
which provide reliable analysis evidence for the test and maintenance of the
battery. It notifies the user to replace battery in advance when the battery
getting aged.

Cranking test is mainly to test and analyze the starting motor. Through testing

AUTOOL BST-100 Battery System Tester User Manual

the actual required cranking current and cranking voltage of the starting motor,
it can find out whether the starting motor works fine. There are several reasons
why the starting motor is abnormal: lubricating system fault causing the
starting loaded torque increasing or rotor friction of the starting motor causing
the increasing friction of the starting motor itself.

Charging test is to check and analyze the charging system, including
generator, rectifier, rectifier diode, etc., thus to find out whether the output
voltage of the generator is normal, the rectifier diode works fine and the
charging current is normal. Suppose one of the above mentioned parts is not in
normal situation, it will lead to over charge or incomplete charge of the battery,
thus the battery will be quickly damaged and also greatly shorten the using life
of other loaded electrical appliance.

Additional functions include: Set language, voltmeter and screen brightness
adjustment.

Chapter 3 Operation

3.1 Pre-Test

3.1.1 Connect Tester

Shake the clamps back and forth to make sure they are well
connected. Tester requires the two clamps are well connected with
the battery poles, otherwise, the test cannot go on. When enter the
battery test program, screen prompts "Check Connection", do clean
the poles and re-connect in the right way.

Tester has reverse connection protection function. When clamps are
reversely connected, tester screen will not light, but it damages
neither the tester nor the automotive load.

NOTE: For parallel connected batteries, break off the cathode
connection first, then do single test to each battery. Suppose
cathode connection is not cut off, there will be error in test result.

After testing: if it's "IN-VEHICLE" test state, press OK key will bring
to Cranking Test.

3.5 Cranking Test

Tester prompts as following:

Starting the engine as prompted, tester will automatically complete
the cranking test and display the result.

Normally, cranking voltage value lower than 9.6V is regarded as
abnormal and it is OK if it is higher than 9.6V.
Test result of the tester includes actual cranking voltage and actual
cranking time.

When cranking test is abnormal, battery test result will also be
displayed at the same time.

AUTOOL BST-100 Battery System Tester User Manual

15

This is for the convenience of the maintenance personnel to quickly
know the whole state of the starting system according to the data.
After testing finished, do not shut down the engine, press OK key to
enter Charging Test.

3.6 Charging System and Rectifier Diode Test

When enter the charging test, tester will prompt "Charging Test?"

Press OK key again to start the charging test.

NOTE: Do not shut down the engine during the test. All electrical
appliance and device are in OFF state. Turn on/off any electrical
appliance in the vehicle during the test will affect the accuracy of the
test result.

Tester will do the following tests in a sequence:

For ripple test, tester will display the real time ripple and meanwhile,
shows ripple volt and charging volt values at the bottom line.
It takes approx. 6 seconds for the ripple test.
After the ripple test, tester will automatically start the loaded voltage
test.

AUTOOL BST-100 Battery System Tester User Manual

16

Loaded Volt Test takes approx. 3 seconds, then it hints "Step on
accelerator to increase engine rotating speed"

Operate accordingly to increase the engine rotating speed to
3000turns or above, and keep for 5 seconds.
Tester starts the charging volt test after increase rev detected.

After the test finished, tester displays the effective charging volts,
ripple test result and charging test result.

NOTE: If no increase rev detected, it shall be the fault of generator
regulator or connection with battery failed. Tester will try 3 times to
further detect, if still failed, it will skip the increase rev detect and
the test result displays "No Volt Output". See below:

Check the connection between generator and battery, then retest.

Charging Test Result:

1) Charging Volt: Normal

AUTOOL BST-100 Battery System Tester User Manual

17

Charging system shows the generator output normal, no problem
detected.

2) Charging Volt: Low
Charging volt of the charging system is low.
Check drive belt of the generator whether slip or running off. Check
the connection between generator and battery is normal or not.
If both of the drive belt and the connection are in good condition,
follow the manufacturer's suggestion to eliminate generator fault.

3) Charging Volt: High

Generator output volt is high.
Since most of the vehicle generators are using internal regulator, the
generator assembly has to be replaced.(Some old style cars are
using external regulator, then directly replace the regulator.)
The normal high volt of the voltage regulator is maximum

14.7±0.5V.If charging volt is too high, it will overcharge the battery.
Therefore the battery life will be shortened and troubles will be
caused.

4) No Volt Output:

No generator volt output is detected. Check the generator
connection cable and the belt whether they are normal.

5) Diode Test:

Through the test of charging current ripple, tester will find out
whether the diode is normal or not. When ripple volt is too high, it
proves at least one diode is damaged. Check and replace the diode.
Till now, all tests have been done.
