Verified product information
The TOPDON BT100 and BT200 are compact battery-system analyzers for 12V lead-acid batteries. Both models evaluate battery condition, cranking performance, charging-system behavior, and ripple for Flooded, AGM, Gel, EFB, and VRLA batteries rated from 100–2000 CCA. Choose BT100 for straightforward 12V diagnostics with a 2-inch backlit display, or BT200 for a 2.4-inch color display plus 24V cranking and charging-system tests. The key distinction is important: neither model performs a 24V battery health test; BT200's 24V capability applies only to cranking and charging-system modes. These testers diagnose—they do not charge, repair, or jump-start a battery.
Passenger vehicles, light trucks, garages, mobile technicians, and DIY users who need a quick lead-acid battery and charging-system check. Use BT200 when 24V cranking or charging-system diagnostics are needed.

For 12V lead-acid automotive batteries only. Select the correct battery type and standard before testing. The listed materials do not verify support for lithium, 6V, or 24V battery health testing.
One selected TOPDON battery tester and a user manual. Confirm package contents with the selected supply source before fulfillment.
Follow the model-specific manufacturer manual. Connect clamps with correct polarity, work around batteries in a ventilated area, and keep sparks or flames away from battery gases. Do not use the tester on visibly damaged or leaking batteries.
Can BT100 test a 24V system? No. Its listed battery, cranking, and charging tests are 12V.
Can BT200 test a 24V battery? No. BT200 performs a 12V battery test; it adds 24V cranking and charging-system tests.
Will either model charge my battery? No. Both are diagnostic tools only.
Do they support lithium batteries? Lithium support is not verified in the supplied materials, so it is not claimed.
