Battery Tester DBT12D MANUAL
1 Product Summary
1.1 Product Profile
The DBT12D Battery Tester utilises the world's current most advanced conductance testing technology to easily, quickly and accurately
measure the actual cold cranking amps capability of the vehicle starting battery, the healthy state of the battery itself, and the common fault
of the vehicle starting and charging systems. This information can help maintenance personnel to find problems quickly and accurately and
thus hastening vehicle repair.
This Battery Tester is able to;
1. Test all automotive cranking lead acid batteries, including ordinary lead acid battery, AGM flat plate battery, AGM spiral battery, Gel
battery, and EFB battery, etc.
2. Detect bad cells and batteries
3. Provide polarity reverse connection protection, reverse connection will not damage the tester or negatively affect the
vehicle and battery.
4. Directly test the battery for loss of electricity, no need to full charge before testing.
5. Testing standards include the world's majority of battery standards, CCA, BCI, CA, MCA, JIS, DIN, IEC, EN, SAE, GB.
6. Support multiple languages: English, Spanish, French, Italian, German and Polish
1.2 Product Function
Main functions of DBT12D battery tester include: battery test, cranking test, charging test and also other additional
functions.
Battery test is used mainly to analyze the battery health status, calculating 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 warns and advises the user to replace
degrading batteries in advance when the battery is getting old and losing efficiency.
Cranking test is mainly to test and analyze the starting motor. Through testing 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 could be abnormal:
it may be a fault in the lubricating system causing the starting loaded torque to increase or rotor friction on the starting motor causing the
increasing friction to itself.
Charging test is to check and analyze the charging system entirely, including the 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. In the case
where one of the above mentioned parts is not in a normal situation, it will lead to over charge or incomplete charge of the battery, causing
battery damage quicker and also greatly shortens the lifespan of other loaded electrical appliances.
Additional functions include: Set language, voltmeter, screen brightness adjustment and
data printing
