Features

📍 Comprehensive Testing in a Compact Tool

The TOPDON BT100 packs pro-level testing into a portable, straightforward design. With the ability to run battery, cranking, charging, and ripple tests, it delivers more versatility and insight than a basic voltage tester—allowing technicians and DIYers alike to diagnose issues with confidence.

📍 Perform Complete Battery Health Check-Ups

The BT100 checks your battery’s State of Health (SOH), State of Charge (SOC), and Internal Resistance, providing a complete assessment of its condition. Results are clearly shown on the display screen, while three LED lights give an instant visual indicator of the battery’s status: GOOD, CHARGE, or BAD.

📍 Understand True Starting Power

The BT100’s cranking test measures starting voltage and cranking time, providing clear data on how the battery performs under starting stress. Quickly identify whether the battery is delivering reliable power or showing signs of weakness.

📍 Pinpoint Charging System Problems

Is it the battery or the alternator? The BT100 makes it clear. Its charging test analyzes ripple, loaded, and unloaded voltage, so you can instantly verify charging system performance and find the solution faster.

📍 One Tester for Lead-Acid 12V Battery

The BT100 tests all 12V lead-acid battery chemistries: regular flooded, AGM flat plate, AGM spiral, GEL, and EFB batteries. With a 100–2000A test range, it delivers accurate diagnostics across everything from compact cars to full-size trucks, making it a versatile tool for both professional shops and home garages.

📍 Clear Results, Anytime, Anywhere

Say goodbye to guesswork. The BT100's 2-inch backlit LCD screen delivers accurate digital results you can easily read in bright daylight, low light, or anywhere in between—so you never have to squint or second-guess again.
