It's a true three-in-one diagnostic tool, combining Battery Health Test, Cranking Test, and Charging System Test in one compact device, so you can quickly identify battery issues, starter faults, or alternator failures without switching tools 【Extra-Large 2.8" Color Display】Features a large 2.8" color display that provides crystal-clear graphics, real-time voltage waveforms, and intuitive icons for easy operation. Its compact size fits easily in your toolbox, while the vivid screen ensures readability even in bright garages or outdoor settings 【Wider Compatibility】Ideal for cars, trucks, motorcycles, RVs, boats, ATVs, and golf carts, this tester is trusted by mechanics, DIYers, and fleet owners. It operates reliably in temperatures from -4°F to 158°F (-20°C to 70°C), and includes a temperature compensation function to ensure accurate results even in cold weather, making it a reliable companion for winter battery checks and pre-trip diagnostics

Accurate Detection & Fast Results: Breathalyzer uses a new generation of high-precision nanosensors that can detect blood alcohol concentration (BAC) from 0.000% to 0.400% with an accuracy of three decimal places. Whether you are detecting trace amounts of alcohol or higher concentrations, you can quickly get reliable results in seconds. Three-Color Warning System: The alcohol breathalyzer uses an IPS high-definition display and an easy-to-read three-color warning system (Green: safe, Yellow: caution, Red: danger), which allows you to clearly understand your blood alcohol concentration (BAC) status at a glance even when you are unconscious. Smart Sobering Time Reminder: Insert the mouthpiece, press and hold the start button, press the button again when the screen lights up, and when the screen displays "BLOW", take a deep breath and blow for 5 seconds to quickly get the test result. The breathalyzer for alcohol will also intelligently estimate when BAC can drop to 0.00%, helping you scientifically control the awake time.

BATTERY TESTING: This handy tool helps you test battery condition and load, check starter motor draw (alternator test), and assists with charging system diagnosis. STARTER AND DEEP CYCLE BATTERIES: Test 12V and 6V starter or deep cycle batteries for cars, pickup trucks, SUVs, motorcycles, RVs, boats, ATVs, motorcycles. For vehicles with up to 1,000 cranking amps SAFETY FEATURES: Rubber insulated carrying handle and color-coded heavy duty alligator clamps to ensure user safety and reliability. Color coded display to quickly identify battery tester results.

[Great-Value Battery tester]: ANCEL BT310 is an all-in-one solution for 12V & 24V lead-acid and lithium batteries, eliminating the need to purchase multiple testers. It supports Flooded, AGM, GEL, and EFB battery types and works with cars, SUVs, light trucks, motorcycles, ATVs, lawn mowers, and boats. Easily diagnose battery health, cranking, and charging systems to maintain peak performance and avoid unexpected failures, even in winter [Professional-Grade Accuracy]: ANCEL battery tester delivers up to 99.98% testing accuracy with clear SOC, SOH, voltage, and internal resistance readings to assess true battery health. It also measures cranking voltage and time, plus charging system performance under load, no-load, and ripple conditions—helping identify whether issues come from the battery, starter, or alternator. It supports all major standards including CCA/BC/CA/MCA/JIS/DIN/IEC/EN/SAE/GB to avoid result variations across different battery ratings [Easy to Use & Understand]: Ready to use out of the box with no charging or technical knowledge required. Simply connect the clamps, select the battery type, and enter the CCA value (usually on the battery label) to start testing. Within seconds, the battery load tester displays one of 5 clear results: GOOD BATTERY, GOOD-RECHARGE, CHARGE & RETEST, REPLACE BATTERY, or BAD CELL-REPLACE, so you know exactly what action to take. The backlit LCD with adjustable contrast ensures clear visibility in bright sunlight or dark garages. (Note: The bottom port is for factory use only)
