【We Have Everything You Need】Each kit includes a BT172 battery tester, alligator clips, an adapter cable, and an instruction manual. We offer repair and technical support for ANENG electrical testers. Buy with confidence. 【BT172】The 12V generator and battery tester has three modes. In intermediate mode, the LCD screen displays the voltage, and the LED indicates the generator status. In 12V mode, the LCD screen displays the voltage, and the LED indicates the battery status. Note: red represents the positive terminal, and black represents the negative terminal. 【Reliable Car Battery Tester】The ANENG BT172 battery tester is designed to test 12V batteries in various vehicles, such as cars, motorcycles, trucks, RVs, ATVs, SUVs, boats, yachts, lawnmowers, and even golf carts. This car battery voltmeter offers accurate readings. of approximately 0.01V, ensuring reliable results. 【Generator Charging System Analysis】In addition to assessing whether the vehicle battery needs to be replaced or jump-started, the BT172 can also evaluate the generator's output status to prevent battery damage due to overcharging or undercharging. 【Protection】The BT172 features reverse polarity protection to prevent damage caused by incorrect connections. The test voltage range is 4-30V DC. If the voltage is outside the permissible range, the screen displays "LO" (<4V) or "HI" (>30V), thus preventing overvoltage. Suitable for 12V batteries, it allows for testing both in and out of the vehicle. Easy to use, compact, portable, and fast, it is widely used in the automotive industry.
