TOPDON BTMobile ProS - Bluetooth 12 V Battery Tester

Battery and electrical-system checks

BTMobile ProS checks 12 V lead-acid batteries, including flooded, AGM, GEL and EFB types. The 100 to 2000 CCA range concerns cold-cranking performance, not ampere-hour capacity. Alongside battery health and state-of-charge assessment, it offers starting and charging-system checks.

Compatible tools and app

Bluetooth connectivity is supported by selected TOPDON diagnostic tools, including compatible Phoenix models. Smartphone BatteryLab support applies to BTMobile ProS serial numbers beginning with 13; it is not a feature of every earlier unit. Before ordering, confirm the serial number and the specific tool or phone you intend to use.

Working with results

Stored results help compare checks during vehicle maintenance. Testing requires the correct battery type, rating and good clamp contact. The tester does not charge batteries, jump-start vehicles or independently replace an OBD diagnostic tool. Confirm the supplied clamps and other accessories as well. Official TOPDON compatibility.
