Features:1. LCD display: clear display, fast response speed, long service life, accurate test value.2. Function: The battery power is continuously tested, not damaged the battery, and has anti -connection and overvoltage protection.3. High -quality materials: high -quality ABS materials, more durable, fixture is firm.4. Durable: equipped with large LED screens and heavy fixtures, and has a bee reminder function to make it more durable and reliable.12V battery tester function:1. Use the STM-32 chip to set the fast and stable operating speed of the hardware. 2. Use a high-precision amplifier and calibrate through a professional battery testing tool. The BST100 reading accuracy is as high as 99 %. 3. The range of CCA 100-2000, 3-220 AH is the best in the market. 4. The voltage of the industrial plan graphics battery is monitored in the same time, and the battery data can be analyzed more accurately. 5. The only battery results are displayed in percentage and instrument mode. 6. Test all cars to start lead -acid batteries, including ordinary lead -acid batteries, AGM tablets, AGM spiral batteries, and gel batteries. 7. Polarity reverse connection protection, reverse connection will not damage the tester or affect vehicles and vehicles and vehicles and batteries. 8. Test the battery directly through the power loss, without sufficient charging before testing. 9. Test standards include most battery standards worldwide, CCA, BCI, CA, MCA, JIS, DIN, IEC, IEC, EN, SAE, GB. Ten SLI], deep cycle and ocean) (AGM)) and gel EPB cellsDisadvantages of the load test method:(1) Only used for large capacitor batteries or energy storage batteries. Small capacitor batteries cannot load a large current of 40-80A within 2-3 seconds. (2) When the battery is large current through the battery, the polarization phenomenon will be generated from the internal electrode, which may cause the internal resistance of polarization. As a result, tests must be tested in a short time. Otherwise, there will be a big mistake in the internal resistance. (3) When a large current passes through the battery, the internal electrode is usually damaged.Product parameters:color: redmaterial: plasticBst100 support language:English, French, German, Russian, Spanish, ItalianThe packaging includes:Tester*1
