Key Features & Benefits

Wireless Bluetooth Connectivity

The BTMobile Lite battery tester connects to your smartphone through Bluetooth 4.0, transmitting data instantly to the free Topdon app. This eliminates the need for a built-in screen, reduces size, and makes the tool more portable while still providing clear, detailed test results.

Three Test Modes in One Device

This battery tester consolidates three essential functions into one compact tool:

• Battery Test – Checks state of health and state of charge for 12V batteries.

• Cranking Test – Measures voltage stability while the starter motor draws current.

• Charging Test – Monitors alternator and regulator performance under load.

With these modes, you can quickly confirm if a no-start issue comes from the battery, starter, or charging system.

Works with Multiple Battery Types

The BTMobile Lite is compatible with a wide range of 12V batteries including Regular Flooded, AGM Flat Plate, AGM Spiral, EFB, and GEL. This versatility makes it suitable for cars, SUVs, light trucks, motorcycles, powersports equipment, and even marine applications.

Safety-First Design

The unit is engineered with multiple layers of protection including reverse polarity protection, short-circuit prevention, and over-voltage safeguards. These features help keep both the tool and the vehicle’s electronics safe during testing.

Simple LED Status Indicators

Two LED lights provide quick visual feedback before you even open the app. A green LED confirms the clamps are correctly connected to the battery, while a blue LED shows that Bluetooth is active and ready to pair.
