Topdon BT Mobile Pro Bluetooth Battery Tester

The Topdon BT Mobile Pro Bluetooth Car Battery Tester 9-24v 100 to 2000CCA


BTMobile Pro, a new-released Bluetooth wireless automotive battery tester, combines the most advanced conductance testing technology to give users accurate test results of the battery condition, starting and charging system, with reverse polarity protection to be a quick, safe and easy battery test solution for technicians, professionals, and DIYers.


-Simply download and install the TOPDON BTMobile App from Apple Store / Google Play to smartphones or tablets (iOS 8.0 & Android 4.3, or above), and sync BTMobile Battery Tester, to experience the most advanced testing technology for 9~24V lead-acid batteries (100-2000 CCA) including regular flooded, AGM flat plate, AGM spiral, GEL and EFB; covering 10 major rating standards: CCA, BCI, CA, MCA, JIS, DIN, IEC, EN, SAE, GB.

-Linger throughout the workspace with this wireless battery tester to have an overall analysis of a batteries health, via its precise and fast Battery Test, Cranking Voltage Test, Charging System Test, without losing a connection. Suitable for checking batteries in motor vehicles, light trucks, RVs, boats, SUVs, ATVs and even tractors

-Fitted with STM-32 main chipset and advanced conductance testing technology, TOPDON BTMobile offers you reliable and accurate load-free test results in seconds, with no need to fully recharge the battery.


-Unique smart 3 LED indicators tell the battery status directly whether it is good, bad, or needs to recharge. Even a beginner can use this portable tester to reveal everything about 9~24V batteries.

6.Standard Testing Range:

CCA: 100-2000 BCI: 100-2000 CA: 100-2000 MCA: 100-2000 JIS: 26A17–245H52 DIN: 100-1400 IEC: 100-1400 EN: 100-2000 SAE: 100-2000 GB: 30Ah-220Ah

    1. Battery Test: Display SOH (State of Health), SOC (State of Charge), Voltage, Current, Rating, and the readable analysis results on App:
    • Display SOH (State of Health, %): Represents a measure of the battery’s ability to store and deliver electrical energy, compared with a fresh battery.
    • Display SOC (State of Charge, %): Expressed as a percentage of its rated capacity, a measure of its condition to assess the potential energy.
    • 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 broken battery 
    1. Cranking Voltage Test: Analyze the actual cranking voltage, and the cranking time to help you quickly figure out the whole state of the starting system
    • Cranking Voltage (Normally a Cranking Voltage value lower than 9.6V is regarded as abnormal.)
    • Cranking Time.
    1. Charging System Test: Test different parts of charging system, including generator, rectifier, rectifier diode etc., for a reliable charging volt value.
    • Loaded Voltage.
    • No-load Voltage.
    • Charging Ripple.
    1. System Test (Overall Test for Battery): Takes some of the guidance away, and offer an accurate insight into batteries’ status, if you are not sure about the battery type and its CCA value.
