PRODUCT SUMMARY

Product Profile
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.

• 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.
• Directly detects bad cell testing.
• Polarity reverse connection protection, reverse connection will not damage the tester or affect the vehicle and battery.
• Directly test the battery with loss of electricity, no need to fully charge before testing.
• Testing standards include currently the world’s majority of battery standards, CCA, BCI, CA, MCA, JIS, DIN, IEC, EN, SAE, GB.

Product Function
The 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’s health status to calculate the actual cold cranking capability of the battery and the aging extent, which provides reliable analysis evidence for the test and maintenance of the battery. It notifies the user to replace the battery in advance when the battery is getting older.
• Starting system 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 is abnormal: lubricating system fault causing the starting loaded torque increase 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.

Note : If the “replacement” is caused by the in car mode, it may be due to the poor connection between the vehicle cable and the battery. Before deciding to replace the battery, make sure to cut off the cable and retest the battery of the vehicle.
Note : After the test, if you need to exit, press the exit key to exit directly to the start-up interface. After test: if it is in the “in vehicle” test status, press enter to enter the climb test.

Starting System Test

• Clamp the red and black clamps of the tester on the tested battery, connect the red to the positive pole and the black to the negative pole, and the display screen will immediately display the start-up interface.
• The main interface appears 2 seconds after start-up. Press the UP/DOWN key to select the battery level, then please select ‘In vehicle’, and then press ENTER to confirm.
• Press the UP/DOWN keys to select ‘starting system test’, and then press the “ENTER” key to confirm.

1. The climb test is normal, and the test result example 1 is displayed.
   Climb test
   Time: 6810ms
   Maximum: 11.55V
   Minimum: 10.24V
   The starting voltage is normal

2.  When the climb test is abnormal, the test result example 2 is displayed.
   Climb test
   Time : 15020ms
   Maximum: 9.05V
   Minimum : 8.55V
   Low starting voltage

Note : Prepare before the test. If the car is starting, please turn off the engine and turn the key to the “OFF” position. Before starting the systemtest, it is necessary to test whether the “CCA” of the battery is normal. If the function of the battery itself is abnormal, the test data of the starting system will be abnormal. After the test, do not shut down the engine, press EXIT to enter the next charging system test.

Charging System And Ripple Test

• When entering the charging test, please select “charging test” and press enter
• Step on the accelerator, turn the engine speed to more than 2500rpm and click the “ENTER” key of the instrument to start the charging test.

Test result:

• if the charging voltage reading is greater than 15.5V, please check the voltage regulator.
• If the reading is greater than 13.3V and less than 15.5V, the charging system is normal.
• f the reading is less than 13.3V, check the connection point, wires and generator

Note: Do not shut down the engine during the test. All electrical appliances and equipment are turned off. Switching on/off any electrical appliance in the vehicle during the test will affect the accuracy of the test results.

The tester will perform the following tests in sequence:
For the ripple test, the tester will display real-time ripple, and display ripple voltage and charging voltage value at the bottom line. The ripple test takes approximately 6 seconds. After the ripple test, the tester will automatically start the load voltage test.

Charging test Load test
The load voltage test takes about 3 seconds, and then prompts “step on the throttle to increase the engine speed”

Charging test

• Increase the speed to 2500rpm
• Hold for 5 seconds. Press OK to continue.
• Operate accordingly to increase the engine speed to 2500rpm or above for 5 seconds.
• When the speed increase is detected, the tester starts the charging voltage test.

Charging test Test
After the test, the tester displays the effective charging voltage, ripple test results and charging test results.

Starting test

• Load 14.16V
• No load 14.39V
• Replace 15MV
• Normal charging

Note: If no increase in speed is detected, it should be a failure of the generator regulator or a failure of the connection to the battery. The tester will try 3 further tests. If it still fails, it will skip the speed increase test, and the test result shows “no voltage output”.

See below:
Check the connection between the generator and the battery and retest.

Charging test results:

1. Charging voltage: Normal
   The charging system shows that the generator output is normal and no problem is detected.

2. Charging voltage : low
   The charging voltage of the charging system is low.
   Check whether the generator drive belt slips or deviates. Check whether the connection between the generator and the battery is normal. If the drive belt and connections are in good condition, troubleshoot the generator according to the manufacturer’s recommendations.

3. Charging voltage: high
   The generator output voltage is high.
   Since most automotive generators use internal regulators, the generator assembly must be replaced (some older cars use an external regulator and then replace the regulator directly.) The maximum normal high voltage of the voltage regulator is 14.7V ±0.5V. If the charging voltage is too high, the battery will be overcharged. As a result, the battery life will be shortened and failure will occur.

4. No voltage output: No generator voltage output detected.
   Check whether the generator connecting cable and belt are normal.

5. Diode test:
   By testing the charging current ripple, the tester will know whether the diode is normal. When the ripple voltage is too high, at least one diode is damaged. Check and replace the diode. So far, all tests have been completed.

Waveform Monitoring
From the startup screen press EXIT button to enter Main Menu. Press the UP/DOWN button to select the [Waveform] function and press ENTER, the screen will display the interface as shown below

• CUR: Current Voltage
• MAX: Maximum Voltage during lgnition
• MIN: Minimum Voltage during Ignition

The waveform will stay in static until there’s changes in the voltage detected. Various vehicle voltage analyses.

• Discharge Voltage: When the Ignition OFF engine OFF (Over 20 Minutes) the Discharge Voltage should be around 12V. If the discharge voltage is lower than 11V it will be hard to turn the ignition ON. lf the discharge voltage continuously stays under 11V it means the battery is aging and replacement is needed.
• Starting Voltage: During ignition, the voltage will drop to a certain point, at this minimum point is Starting Voltage (Around 7.5-9.5V). If the Starting Voltage continuously stay under 7.5V it means battery capacity is low and needs to be replaced.
• Charging Voltage: When the ignition ON engine ON. The alternator will continuously charge the car battery, normally is around 14V.
