The Topdon BT100 is a battery tester designed for analyzing the condition of 12V lead-acid batteries. The tester measures various parameters to provide a complete picture of the battery's health, such as the State of Health (SOH) and State of Charge (SOC). The device is suitable for batteries with a capacity within a range of 100 to 2000 CCA and supports a wide range of battery standards.

In addition to the standard battery test, the BT100 also performs a start test and a charge test. This not only analyzes the battery itself but also the performance of the vehicle's starting and charging system. The tester features built-in reverse polarity protection, preventing damage to the tester's electronics and the battery. The results are displayed on a clear and readable LCD screen.

Application and functionality:

The tester offers multiple diagnostic functions for a complete analysis of a vehicle's battery system.

  • Battery test: Analyzes the battery to determine the health status (SOH), charge status (SOC), internal resistance, and the actual CCA value.
  • Start test: Measures the starting voltage and start time to check the operation of the vehicle's starting system.
  • Charge test: Checks the operation of the charging system (alternator) by measuring the charging voltage under no-load and load conditions, including a charge ripple test.
  • Reverse polarity protection: Internal protection prevents damage if the clamps are connected incorrectly to the battery terminals.

Supported battery types:

The Topdon BT100 is compatible with the most common types of 12V lead-acid batteries.

  • Regular lead-acid (Flooded): Standard wet cell batteries.
  • AGM (Absorbent Glass Mat): Both flat plate and spiral variants.
  • GEL: Batteries where the electrolyte is in gel form.
  • EFB (Enhanced Flooded Battery): An improved version of the standard wet cell battery.

Supported battery standards:

The tester supports various international standards for battery classification.

  • CCA: Cold Cranking Amps
  • BCI: Battery Council International
  • CA: Cranking Amps
  • MCA: Marine Cranking Amps
  • JIS: Japan Industrial Standard
  • DIN: German Institute for Standardization
  • IEC: International Electrotechnical Commission
  • EN: European Standard
  • SAE: Society of Automotive Engineers
  • GB: Chinese National Standard

Test functions

Measures the condition, state of charge and cold start current of the battery. This shows whether the battery is still good or needs replacing.Battery test
Measures how far the voltage drops when the engine starts. This shows whether the starter motor draws too much current.Start test
Checks whether the alternator charges the battery properly. Useful if the battery keeps going flat.Charging system test
Measures disturbance in the charging voltage. This helps find a faulty diode in the alternator.Ripple voltage test
Shows the internal resistance of the battery. A high resistance indicates a worn battery.Internal resistance measurement
