- 🚗 [ 12V & 24V Car Battery r ]: AUTDER AD-808 automotive battery r works on all 12 Volt and 24 Volt batteries for vehicles, cars, motorcycles, trucks, RVs, ATVs, SUVs, boats, yachts, mowers, and even golf carts. The accuracy of the car battery voltmeter is close to 0.01V, such as 12.29V.
- 🔥 [ Alternator Charging System Analyzer ]: Except for providing a quick reading to determine if a vehicle battery needs a jump or replacing, It can also test the alternator output status to avoid damaging the battery because of overcharge or incomplete charge.
- 🎯 [ Easy Operation ]: We creatively designed three gears to test the alternator, 12V battery, and 24V battery respectively. When keeping the gear in the middle, the LCD screen displays the real-time voltage, the LEDs indicate the alternator status, When shifting to 12V or 24V gear, the LCD screen displays the real-time voltage and the LEDs indicate battery status.
- 👍[ Reverse-hookup & Over-voltage protection]: While connected reversed, the LCD screen will display the error code 'ERR' and the built-in buzzer will sound. The Digital Voltage test range is 4-30V DC, when the voltage is out of range, the screen will display 'LO'(＜4V) or ‘HI’ (＞30V).
- 🙂[ Package & After Sales Service]: 1*AD-808 Battery r, 1*Alligator Clamps, 1*Cigarette Lighter Plug Adapter Cable, 1*User Manual. We provide you with 1 year of warranty service and 24h on-line service, If you have any questions, please freely 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
