1. PRODUCT SUMMARY

The MT245 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.

Ÿ Test all automotive cranking lead acid battery, including ordinary lead

acid battery, AGM flat plate battery, AGM spiral battery, and Gel battery,

EFB battery, etc.

Ÿ Directly detects bad cell batteries.

Ÿ Polarity reverse connection protection, reverse connection will not

damage the tester or affect the vehicle and battery.

Ÿ Directly test the battery with loss of electricity, no need to fully charge

before testing.

Ÿ Testing standards include currently the world's majority of battery

standards, CCA, BCI, CA, MCA, JIS, DIN, IEC, EN, SAE, GB.

Main functions of the MT245 battery tester include: battery test, starting

system test, charging system 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 use to replace the battery in

advance when the battery is getting older.

Starting system test is mainly to test and analyse 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 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 system test is to check and analyse 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 a 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.
