2. Product Introduction:
BT460 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 cranking system
and charging system, which can help maintenance personnel to find the problem quickly and
accurately, thus to achieve quick vehicle repair.
1. Application: 12V automotive cranking lead acid battery, new cranking lithium battery and
12V/24V car system test
2. Measure Range:
3. Working Environment Temp.: -20°C-50°C
4. Special test clip: Double conductance Kelvin clamp
5. Housing Material: Acid-resistant ABS plastic
6. Current Measure Range: 4AH-240AH
7. Voltage Measure Range: 6V - 30V
3. Product Use
3.1 Battery Test
1. Connect the red test clamp with battery positive(+) and the black clamp with negative(-), the tester
will power on automatically. Battery voltage below 6.0V can’t be tested properly, then press any key
to continue.
2. Select according to the tester display:
(1) Test standard: The standard which you can read from the top or front of the battery , such as
CCA, IEC, DIN. If you can’t find any information about the standard, AH of battery capacity can be

used as a reference. Choose similar battery standard, and it will cause small error.
(2) Rated capacity: You can read the cranking current standard in the top or front of the battery,
such as CCA 370.
(3) Press ENTER key to start testing.
For small battery, the lower resistance it is, the healthier the battery is (except
short-circuit). Resistance can be used as a reference for the battery state.
Battery Test Result (for example)
Battery voltage 12.5V --------- Voltage when testing the battery
Measurement 400A（ CCA ） ----cranking current for testing
Resistance 18.5m Ω ------Battery resistance
Life 95% ----------- Battery remaining life
Test result Good ------------ Battery state
Note:
a. When battery voltage is lower than normal test voltage, the test result cannot
check the battery state properly. It will show “Re-test after charging ”. At this time,
please charge the battery, then test it.
b. When battery voltage is too high or the vehicle is starting, the test can’t be
proceeded. It will show “The voltage is too high. Please turn off the engine!
Please turn on the headlights in 3 minutes, then test it. ”
c. For serious battery shortage (For example, the vehicle is on hold for a long time; the
battery is not charged in time; the headlight or door is forgotten to be turned off, which
cause serious battery shortage, and vehicle can’t start), it may show “Please replace
the battery” during test. For such batteries, please consult the battery manufacturer to
restore charging , then test it.
3.2 Cranking Test
After battery test, press UP/DOWN key to select cranking test. Then, press ENTER
key to cranking test:
Current 12.5V ---- current voltage
Min imum voltage 11.1V --------Minimum voltage tested
Minimum cranking voltage 9.6V -------Cranking voltage lower than 9.6V is
regarded as abnormal, which may be caused by battery aging which can ’t provide
sufficient cranking current, or because of starter worn or poor mechanical lubrication.
In the state of engine off, it will show “Start engine, and wait for 15 seconds! ”
Start engine, and wait for the test result.
3.3 Charging Test
In the menu, press UP/DOWN key to select charging test. Press ENTER key to
charging test. It will show:
Start engine, and wait for 15 seconds!
Press ENTER key to start charging test!
At the same time, start engine. When engine running is stable, press ENTER key to
display test state:
Charging test
Maximum
14.5V <15.0V normal
Current
13.8V
Minimum
13.6 >13.3V normal
Note: Do not shut down the engine during the test. All electrical appliance and
device should be in OFF. During the test , turn ing on/off any electrical appliance
in the vehicle will affect the accuracy of the test result.
The battery voltage will be different because of different engine conditions. Normally,
charging voltage cannot be lower than 13.3V, higher than 15.0V even in high-speed
rotation.
Charging voltage is too low:
Charging system voltage is not enough.
Please check if generator belt slips or runs off, if the generator connects well with the
battery.
If the generator belt and connection are good, please follow the manufacturer's
suggestion to avoid generator failure.
Charging voltage is too high:
Generator output voltage is too high.
Since most of the vehicle generators are using internal regulator, the generator
assembly has to be replaced. (Some old vehicle are using external regulator, then
replace the regulator directly.)
Normally, the maximum voltage of regulator is 14.7V. If charging volt age is too high,
the battery will be overcharged, which will shorten battery life and cause battery
failure .
3.4 Load Test
In the menu, press UP/DOWN key to select load test. Press ENTER key to load test. It
will show:
Please turn on all the electrical appliance and device
Start engine, and wait for 15 seconds!
Press ENTER key to start load test!
At the same time, start engine. When engine running is stable, press ENTER key to
display test state:
Load Test
Current 14.1V
Minimum 13.5V
Minimum when all on 12.8V
When all appliances are in ON state, normally, charging voltage is more than 12.8V if
the power supply from generator is sufficient. If the voltage is less than 12.8V, it may
be caused by insufficient output current from generator, reduced power generation,
excessive electrical load or leakage. Increasing the electrical appliances in the vehicle,
it will also cause a voltage drop.
4. Language
In the menu, press UP/DOWN to select language setting. Press ENTER key to
language setting. It will show:
Language
1.English
2.Portugu ese
3.Espa ña
4.French
...
Press UP/DOWN to select the language, then press ENTER key to save. Press ESC to
exit. Then, you can proceed other test.
