AUTOOL BT-660 Battery Conductance Tester
User MANUAL

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.

How to use:
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:
①Battery Test
②Cranking Test
③Charging Test
④Review Data

(1) 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, p;ease consult the
battery manufacturers, and then tested.
Following:

Starting the engine as prompted, tester will automatically coplete
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.
This is for the convenience of the maintenance personnel to quickly

know the whole state of the starting system according to the data.
(3) 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 rev detected.

After the test finished, tester displays the effective ,charging ,volts,
tipple 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”.
Check the connection between generator and battery, then retest.
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: Hight. 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.
