1. Introduction
The FOXSUR FTC-1206 is a versatile 2-in-1 device combining a 12V smart battery charger and a battery tester. It is designed to charge 12V lead-acid, AGM, GEL, EFB, Deep Cycle, WET, and LiFePO4 batteries ranging from 4AH to 120AH. The integrated battery tester utilizes advanced conductance testing technology to quickly and accurately measure the actual cold cranking amps (CCA) capability, state of health (SOH), and state of charge (SOC) of vehicle starting batteries. This helps in identifying battery issues efficiently for quick vehicle repair and maintenance.

6.2 General Care
- Keep the device clean and dry. Wipe with a soft, damp cloth if necessary.
- Store in a cool, dry place away from direct sunlight and extreme temperatures.
- Regularly inspect cables and clamps for any damage. Replace if worn or damaged.
7. Troubleshooting
7.1 Battery Tester Issues
- Q: Nothing is displayed on the screen.
A: Ensure your battery voltage is higher than 8V and the positive and negative clamps are connected correctly to the battery terminals. - Q: The test results are inaccurate.
A: Double-check that the battery parameters (AH for MOTO, CCA for CAR) you entered match the information on your battery's label. Incorrect input will lead to inaccurate results. - Q: Can the tester be used on 24V batteries?
A: The tester is designed for 12V batteries. For 24V series batteries, you must disconnect the series cable and test each 12V battery individually.
