The 12V/24V Car Battery Tester is a Battery Condition Tester and Alternator Charging System Analyzer, featuring an Automotive Voltmeter with an LCD Display and LED Indication. The voltage test range is 4-30V DC, and if the voltage is out of range, it will indicate "LO" (＜4V) or "HI" (＞30V).

The battery tester has three gear modes: 12V, 24V, and Middle Gear. In the middle gear, it can be used to connect to the battery without the vehicle running and read the battery status via the left side light. In the middle gear, it can also be used to connect to the alternator, start the car engine, and read the alternator status via the right side light, allowing for quick determination of the alternator's condition.

The AUTDER AD-808 battery tester is designed for testing 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 the car battery voltmeter is close to 0.01V, providing reliable results.

In addition to determining whether a vehicle battery needs replacement or a jump, the AD-808 can also test the status of the alternator output to prevent damage to the battery from overcharging or incomplete charge. The device comes equipped with reverse-hookup protection, preventing damage in case of an incorrect connection.

Each package includes the AD-808 battery tester, alligator clamps, a cigarette lighter plug adapter cable, and a user manual. We provide one year of warranty service and 24-hour online support. If you have any questions, please don't hesitate to contact us.
