AUTDER AD-808 Car Battery Tester

12V/24V DIGITAL BATTERY TESTER

Model: AD-808

Function

Designed to test the 12V/24V battery voltage or the voltage of the charging system.
With LED display and LED battery status indicator.
The rubber body comes with a crocodile clip for connection.
Reverse connection error and over-pressure protection. Safe and easy to use.

Instructions For The Operation

Properly connect the battery clip to the battery post. The red clip is connected to the positive “+” of the battery and the black clip is connected to the negative “-” of the battery. If connected reversed, the LCD screen displays the error message “ERR” and the buzzer will sound, displaying the actual voltage of the battery under test correctly after 5 seconds, while the LED light will light up to indicate the battery’s real-time status.
If connected correctly, the LCD screen lights up and displays the voltage of the battery under test, while the LED light lights up to indicate the battery status.
The switch has a total of three gears (default in the middle gear), the LCD screen displays “12V” and “V” when dialed to 12V (right), while the LED light lights up to indicate a 12V battery voltage rating status light, and “24V” when dialed to 24V (left) and “V”, while the LED lights up to indicate a 24V battery voltage rating status light, and when dialed to the middle position (both clips are empty) display only the “V” and the real-time voltage value of the battery or generator, automatically identify the 12/24V battery, higher than 18V means the 24V battery system.
To test the alternator charging system, adjust the switch to the middle position, keep the tester connected to the battery post, and then start the engine. The output voltage will display on the LCD screen and the LED light on the right lights up to show the alternator status.

Refer to the LED-related instructions below:

FULL – The LED light comes on in FULL gear. Battery in normal condition (12.6-13.5V on a 12V battery).
MEDIUM – The LED light comes on in the MEDIUM gear. The battery voltage is slightly lower. Charge required.
LOW – The LED light comes on in LOW gear. The battery is low. Charge required, buzzer prompt.
EMPTY – The LED light comes on in EMPTY gear. The battery is completely powered out. Charge required, buzzer prompt.
DEAD – The LED light comes on in DEAD gear. The battery voltage is too low. The battery should have a battery problem. Check the battery by a professional battery engineer to see if it should be replaced.
REVERSE – The LED light comes on in REVERSE gear. The battery tester is connected in reverse to the battery post, the buzzer prompts.
GOOD – The LED light comes on in the GOOD gear. The alternator output voltage is CORRECT.
HIGH – The LED light comes on in the HIGH gear. The alternator output voltage is high. The normal output of the alternator voltage is 13.6-14.5V on a 12V battery.

WARNING!

Only for 12V/24V batteries or 12V/24V charging systems.
The voltage test range is 4-30V DC, and if the voltage is out of range, the screen will display “LO”: <4V or “HI”:> 30v.
Store the tester in a box after each use to protect the circuit.

The voltage test table is as follows:

12 Voltage range | 12.6-14.5V | 11.9-12.6V | 9.9-11.9V | ≤9.8V | battery voltage
Lamp name | HIGH (high voltage) | GOOD (normal) | DEAD (charge bad) | REVERSE (reverse)
24 Voltage range | ≥14.6V | 13.0-14.5V | ≤13.0V | Connected in reverse to test high-level power | Generated voltage

FEATURES

Dual Voltage Compatibility: The AD-808 can test both 12V and 24V batteries, so it can be used in a lot of different vehicles, like cars, trucks, bikes, and more.
LED monitor: It has an easy-to-read LED monitor that shows the alternator’s condition and the battery voltage.
Full, Medium, Low, Empty, and Dead battery states are clearly shown by the Battery Status Indicator, which helps users quickly figure out what’s wrong with the battery.
Alternator Testing: This feature checks the alternator’s performance to make sure it gives off the right power.
Reverse Polarity Protection: The tester and the car’s electrical system are protected against reverse polarity while they are being used.
Over-Pressure Protection: This feature keeps the tester and battery from getting damaged by too much power.
Built to last: The base is made of strong rubber and other high-quality materials so it can handle daily use in a variety of settings.
Crocodile Clips: It comes with strong crocodile clips that make the link to the battery wires safe and stable.
Small and Lightweight: The form is small and light, making it easy to store and move.
User-Friendly Operation: A simple design with clear directions makes it easy to use, even for people who aren’t very tech-savvy.
Real-Time Voltage Measurement: Gives voltage data in real time, so users can keep a close eye on the battery’s health.
Detection of Errors: Shows error signs like “ERR” for bad links, which helps users figure out problems quickly.
Automatic Identification: This feature figures out whether the battery is 12V or 24V on its own, which makes testing easier.
Buzzer Alerts: It has a loud buzzer that lets users know when there are backward connections or low batteries.
LED Backlight: The screen is brightened with LEDs so it’s easy to read in low light.
Wide Temperature Range: Made to work well in a lot of different temperatures, so it will work reliably in many different regions.
Safety: It meets the global safety standards for testing tools used in cars.
Easy Alternator Testing: A few easy steps can be used to test the charging system of the alternator and get quick results.
Long Cable Length: Comes with cords that are long enough to reach the battery connections without any trouble.
Energy-efficient: The device doesn’t drain the battery during tests because it doesn’t use a lot of power.
