## Description

AUTDER Car Battery Tester and Alternator Tester 12V/24V with LCD Display and LED Indication Automotive Battery Voltage Meter for Cars Trucks Motorcycles

## Features

- Reliable Battery Testing: The AUTDER AD-808 battery tester is designed to test both 12V and 24V batteries for a wide range of vehicles including cars, motorcycles, trucks, RVs, ATVs, SUVs, boats, yachts, mowers, and even golf carts. The accuracy of this car battery voltage meter is close to 0.01V, providing reliable test results.
- Alternator Charging System Analysis: In addition to determining if a vehicle battery needs replacement or a jump start, the AD-808 can also assess the status of the alternator output, preventing battery damage from overcharging or insufficient charging.
- Easy to Use: With its intuitive design, the AD-808 features three gear modes for testing the alternator, 12V battery, and 24V battery respectively. In the middle gear, the LCD screen displays real-time voltage while the LEDs indicate the alternator status. Switching to the 12V or 24V gear shows the real-time voltage on the LCD screen, and the LEDs indicate battery status.
- Protection Features: The AD-808 is equipped with reverse-hookup protection to prevent damage to the device in case of incorrect connections. Additionally, the voltage test range is 4-30V DC, and when the voltage is out of range, the screen displays 'LO' (30V), ensuring protection against over-voltage.
- Warranty and Service: Each package includes the AD-808 battery tester, alligator clamps, a cigarette lighter plug adapter cable, and a user manual. We provide a one-year warranty and 24-hour online support. If you have any questions, please don't hesitate to contact us.

## Questions & Answers

**Q: How do I test the alternator?  Hooked up to battery, got a voltage reading, started the car but it doesn't show anything on the alternator side**
A: Leave the tester on the battery, it should read at least 12v, start your car, if the reading didn't go up for at least 14v, you're alternator is not working....

**Q: What is the Cigarette lighter adapter for?**
A: to test the battery through the cigarette lighter of the car instead of raising the hood and clamping on the battery.

**Q: Will this also work on a 12v marine battery?**
A: Absolutely. It should register around 12.0-12.6 volts when the vehicle it turned off. 
If it registers a little higher when the vehicle is running, then that means your alternator is working perfectly fine. It’s a great tool to have. It’s good to check your battery every once in a while. It’s worth the money.

**Q: Can this tester be used with three batteries wired in parallel?**
A: If the battery voltage in parallel or series exceeds 3V, it can be measured
