TOPDON BT100 / BT200 Battery Tester
TOPDON BT100 / BT200 Battery Tester
General Details
General Details
The TOPDON BT100 and BT200 are compact automotive battery testers designed to assess battery condition, starting performance and charging-system operation. Both models provide fast diagnostic information for 12V lead-acid batteries, while the BT200 also supports 24V cranking and charging-system testing.
The BT100 is suited to everyday 12V battery diagnostics, while the BT200 provides additional 24V capability for larger vehicles and electrical systems.
Battery Testing
Both models evaluate battery condition using electrical measurements to provide information on battery performance and remaining capacity.
• Battery Test: 12V
• Battery Type: Lead-acid
• Battery Chemistries: Flooded, AGM Flat Plate, AGM Spiral, GEL and EFB
• Test Range: 100–2000 CCA
• Battery Analysis: State of Health (SOH) and State of Charge (SOC)
• BT100: Also measures internal resistance
• BT200: Measures battery voltage and CCA performance
Cranking Test
The cranking test evaluates how the battery performs when starting the vehicle by measuring starting voltage and cranking duration.
• BT100 Cranking Test: 12V systems
• BT200 Cranking Test: 12V / 24V systems
• Measurements: Starting voltage and cranking time
• Purpose: Helps identify weak starting performance and potential battery issues
Charging System Test
The charging test helps assess alternator and charging-system performance by monitoring vehicle voltage under different operating conditions.
• BT100 Charging Test: 12V systems
• BT200 Charging Test: 12V / 24V systems
• BT100: Loaded voltage, unloaded voltage and ripple testing
• BT200: Loaded and unloaded voltage testing
• Applications: Alternator, regulator and charging-system checks
BT100 Additional Features
The BT100 provides several functions within a compact handheld design.
• Battery Health: SOH, SOC and internal resistance
• Battery Status Indicators: GOOD, CHARGE and BAD LED indicators
• Ripple Test: Helps identify charging-system irregularities
• Backlit LCD: Designed for clear viewing in different lighting conditions
• Compact Design: Suitable for workshops, garages and mobile diagnostics
BT200 Additional Features
The BT200 provides expanded testing capability for both 12V and 24V vehicle systems.
• 12V / 24V Cranking Test: Supports both system voltages
• 12V / 24V Charging Test: Suitable for a wider range of vehicles
• 2.4-Inch Colour LCD: Displays battery and test information clearly
• Portable Design: Compact enough for workshop or roadside use
• Simple Operation: Connect the test clamps to the battery terminals and follow the on-screen instructions
Display
The two models use different display configurations for presenting test results.
• BT100 Display: 2-inch backlit LCD
• BT100 Resolution: 128 × 64 pixels
• BT200 Display: 2.4-inch colour LCD
• BT200 Resolution: 320 × 240 pixels
