2. Introduction:
Battery Conductance Tester BT 660 adopt 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.
3. Product specification:
1. Application: 12V automotive cranking lead acid battery and 12v/24v car system test.
2. Measure Range:
CCA 100-3000
BCA 100-3000
CA 100-3000
MCA 100-3000
4. Working Environment Temp:-12℃-50℃
5. Special test clip: Double conductance Kelvin clamp
6. Housing Material: Acid-resistant ABS plastic
7. Measure Range: 30AH-200AH
8. Voltage Measure Range: 7-30VDC
4. How to use:
4.1 Basic steps
1. Connect the red test clamp with battery anode and the black one with cathode, the tester will power on
automatically. Voltage battery below 7.0VDC can’t be tested properly, then press OK key to continue.
2. According to the tester, you can press UP/DOWN key to choose:
① Battery Test
② Cranking Test
③ Charging Test
④ Review Data
⑤ Print Data
⑥ Export Data to Computer
4.2 Battery Test
Select the battery test and press OK key to continue:
* Battery Type: select your battery type, usually is “Regular Flood”
* Input testing standard: the standard which you can see the front of the battery, such as CCA/BCI/DIN.
If you can’t find any info about the standard, you can choose GB standard. Choose GB standards would
lead little tolerance.
* Input rated capacity; you can see the starting current standards in front of the battery. Such as
BCI/300A.
* Then press OK key to start testing
Note:
For power loss battery (such as a vehicle for a long time on hold,the battery is not charged in time; forget
to close the lights, the doors resulting in serious loss of battery electric vehicle and can not be started,
etc.), in the actual testing process may also be prompted to “Please replace the battery,” for such
batteries, please consult the battery manufacturers, and then test.
JIS 26A17-245H52
DIN 100-2500
IEC 100-2500
EN 100-2500
SAE 100-3000
GB 30AH-220AH
4.3 Cranking test:
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.
（改 CRANKING）
When cranking test is abnormal, battery test result will also be displayed at the same time.
（改 CRANKING）
This is for the convenience of the maintenance personnel to quickly know the whole state of the starting
system according to the data.
4.4 Charging Test
When enter the charging test, tester will prompt “Loaded testing”
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.
Operate accordingly to increase the engine rotating speed to 2500turns, and keep for 5 seconds.
Tester starts the charging volt test after increase rotation detected.
After the test finished, tester displays the effective ,charging ,volts, tipple test result and charging test
result.
NOTE: If no increase rotation 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
rotation detect and the test result displays “No Volt Output”.
Check the connection between generator and battery, then re-test.
Charging Test Result:
1.Charging Volt: Normal. The generator output normal, no problem detected.
2.Charging Volt: 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. 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, the drive
belt of generator and engine whether normal or not.
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.
5. Additional Function:
Press”Menu” to enter additional function:
1) Review Data
