2 Modes for Battery Test

The TOPDON BT500P is a great option for those who need to check their automotive batteries on the regular. The tester comes to an innovative user-friendly design of introducing both a “Quick Test” and “Accurate Test” to get a precise estimation of a battery, depending on your experience level or needs:

l  Quick Test: Takes some of the guidance away from your hands, if you are not sure about the battery type and its CCA value.

l  Accurate Test: is used for getting an accurate reading of your battery’s capacity status.

In a nutshell, you can:

ü  Display SOH (State of Health, %):Represents a measure of the battery’s ability to store and deliver electrical energy, compared with a fresh battery.

ü  Display SOC (State of Charge, %): Expressed as a percentage of its rated capacity, a measure of its condition to assess the potential energy.

ü  Display Battery Internal Resistance Value (mΩ): The lower the internal resistance, the more current the battery can output. The value above 15 milliohms indicates a faulty battery (12V).


Cranking Voltage Test

This load tester actually checks the cranking effectiveness of the battery, and helps you predict when the battery will fail to crank a vehicle. It displays the Cranking Voltage parameters as follows in seconds, for you to make a decision on battery maintenance:

-  Current Voltage

- Instant Minimum Starting Voltage

- Standard of Instant Minimum Starting Voltage

-Normally a Cranking Voltage value lower than 9.6V is regarded as abnormal.

-The engine and all other accessory loads must be OFF during the test.


Max Work Load Test

Sometimes, a battery may have enough power to start your engine, but the electrical system can’t support the increased load of operating other electrical things like your headlights or radio. According to the result of the max work load test from TOPDON BT500P, you can get to know the health status of the battery load system, and make sure if the battery is in a good condition.

l  If > 12.8V (25.60V for 24V), the load system is working well.

l  If < 12.8V (25.60V for 24V), check the engine belt abrasion and the electrical short circuit.


Charging System Test

Chronic undercharging can also cause premature battery failure. The battery tester TOPDON BT500P boasts a thorough charging system test, to help you avoid unpredictable system interruption, and prevent the batteries from being overcharged and over discharged, which may also cause permanent damage to the internal structure of batteries.

By simply following the guidance you will get the test results as follows:

- The maximum value of output voltage

- The average value of output voltage

-  The minimum value of output voltage

Check the reference table in the product manual, you will have a basic idea of your charging system status.
