Key Features:
- Supports 12V and 24V batteries.
- Tests various battery types: VRLA, GEL, AGM, EFB, STD (Regular Flooded).
- Measures Internal Resistance, Battery Voltage, CCA Value, Status of Charge (SOC), and Status of Health (SOH).
- Features reverse connection protection.
- Compact and portable design.
2. Setup and Connections
Before using the FBT200, ensure the battery terminals are clean and free of corrosion for accurate readings.
Connecting the Tester:
- Identify the positive (+) and negative (-) terminals on your vehicle battery.
- Connect the red positive (+) clamp of the FBT200 to the positive (+) battery terminal.
- Connect the black negative (-) clamp of the FBT200 to the negative (-) battery terminal.
- The tester will power on automatically once correctly connected to a battery with sufficient voltage (above 8V).

Controls and Display:

- Up Arrow: Previous item, or increase battery rating values.
- ESC (Escape): Cancel button.
- Down Arrow: Next item, or decrease battery rating values.
- ENTER: Confirm; Enter and proceed.
- RESET: Reset / Restart.
- Positive battery test clamp.
- Negative battery test clamp.
3. Operating Instructions
The FBT200 allows for quick and comprehensive battery analysis. Follow these steps to perform a test:
- Connect the Tester: As described in Section 2, connect the red clamp to the positive terminal and the black clamp to the negative terminal of the battery.
- Select Test Program: Use the Up/Down arrow buttons to navigate through the menu options.
- Input Battery Parameters: Select the correct battery type (VRLA, GEL, AGM, EFB, STD) and input the Cold Cranking Amp (CCA) value as marked on your battery label. Use the Up/Down arrows to adjust values and ENTER to confirm.
- View Test Results: The tester will display results within approximately 3 seconds.
Interpreting Results:
The FBT200 provides detailed information about your battery's condition:
- Internal Resistance (I.R): Indicates the battery's ability to deliver current. Lower values are better.
- Battery Voltage (VOLT): The current voltage of the battery.
- CCA Value (EDC): The measured Cold Cranking Amps, crucial for starting performance.
- Status of Charge (SOC): Percentage of charge remaining in the battery.
- Status of Health (SOH): Overall health percentage of the battery, indicating its remaining lifespan and performance capability.

4. Maintenance
To ensure the longevity and accuracy of your FBT200 battery tester, follow these maintenance guidelines:
- Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the tester in a dry environment, away from direct sunlight and extreme temperatures.
- Cable Care: Avoid bending or kinking the test cables excessively. Inspect clamps and cables regularly for damage.
5. Troubleshooting
Here are solutions to common issues encountered with the FBT200:
- No Display:
- Ensure the battery voltage is higher than 8V. The tester is powered by the battery being tested.
- Verify that the positive and negative clamps are connected correctly to the battery terminals. - Inaccurate Test Results:
- Confirm that the battery type and CCA values entered into the tester match the specifications on the battery label. Incorrect input parameters will lead to inaccurate readings. - FBT-200 Does Not Charge Batteries:
- The FBT200 is a battery analyzer and tester only; it does not have charging capabilities. - FBT-200 Does Not Have Internal Power:
- The device operates solely by drawing power from the battery it is testing. It does not contain an internal battery.
